Résumé :
In this work, henequen and ixlte plant fibers were carbonized in a horizontal quartz tube furnace. Several carbonized and non-carbonized fiber fabric configurations were impregnated with a bio-based epoxy resin through the infuseon process. The infrared spectra revealed characteristic bands of styrene instead of organic compounds, representing that the carbonization procedure was adequate to carbonize the plant fibers. The porosity volume ratio for the non-carbonized henequen laminates showed the highest number of voids >1.9%, and the rest of the composites had a similar void density between 1.2–1.7%. The storage modulus of the non-carbonized and carbonized henequen laminates resulted in 2268.5 MPa and 2092.1 MPa, respectively. The storage modulus of the carbonized ixtle laminates was 1541.4 MPa, which is 37.8% higher than the non-carbonized ixtle laminates and 12% higher than henequen composites. The laminates were subject to thermal shock cycling, and tomography scans revealed no alterations on the porosity level or in the cracks after the cycling procedure. Thermal shock cycling promoted the post-curing effect by increasing the glass transition temperature. The viscoelastic results showed a variation in the storage modulus when the carbonized fiber fabrics were located between natural fiber fabrics, which was attributed to more excellent compaction during the infusion process. Variations in the viscoelastic behavior were observed between the different types of natural fibers, which influenced the mechanical properties.

Résumé :
Ixtle is the name given to the hard fibers de rived from agave plants (Agave spp.: Agavaceae). Ixtle has been used in the Mexican State of Oaxaca since pre-Columbian times, mainly by zapatee and mixtec communities, in order to fulfill their basic needs such as dress and the elaborations of items for agricultural use, chiefly strings and leashes. Several species are used: Agave angustifolia Haw., A. americana L. var. americana,A. americana L. var. oaxacensis Gentry, A. angustiarum Trel., and A. kerchovei Lem. The ixtle fibers are obtained using fresh or dry leaves, employing different methods that vary depending on the water availability. The described methods are enriado, majado or machucado, oven treatment and dry extraction of the fibers. The different methods used in the extraction of the fibers trans late in their quality. The enriado method produces fibers with the best quality for the products described above. The spin of the fibers for making the ropes includes the torno or rueca (a spinning wheel) of European origin, and the tarabilla, a pre-Columbian instrument.

Résumé :
The effect of two commercialin vivotransport methods (cardboard boxes and ixtle sacks) on the physiological condition of Japanese oyster (Crassostrea gigas) was evaluated. Total carbohydrates, glycogen, adenosine 5′-triphosphate (ATP) and related products, adenylate energy charge (AEC), and pH of transported oysters in simulated conditions were determined. The results showed that the ATP initial concentration was low from the beginning of the experiment, and AEC decreased in both transport methods. With respect to the total carbohydrates and glycogen, the samples maintained in cardboard box and ixtle sack decreased during transport, respectively. Similarly, significant changes in pH were observed for both methods. Our results showed that physiologically the bestin vivotransporting method for Japanese oyster is in cardboard boxes.

Résumé :
The purpose of this study is to analyze the main components of a typical Lechuguilla Ixtle shredder machine, present in most of theejidos dedicated to this activity in the northeast of Mexico, and to determine the opportunities for redesign its main parts, also thesound and vibration levels for evaluate their magnitude and determine the severity and impact. To achieve this objective, the DFXmethodology was applied to Lechuguilla Ixtle shredder machine knowing the main parts that are susceptible to redesign, this typicalmachine was also compared against a bench test, carried out in a workshop with a lower power motor, with which were made testsfor noise and vibration, in both cases the analyzes are perform out with the same intention of achieving an improvement in itsefficiency. The results of the DFX methodology, as opportunities for redesign are: the safety of operation, the input and outputmechanisms, speed working when defibrating two Cogollos, lightening the structure, motor capacity depending on the design of thedefibration roller, and the form of maintenance and inspection. Finally, in the analysis of noise and vibrations, there areopportunities for improvement in the design of the machinery drum, placing a guard (cover) that helps to reduce noise levels, andreviewing the alignment of the axes the machinery so as not generate vibration outside the allowable ranges

Résumé :
This work deals with the manufacture and mechanical characterization of natural-fiber-reinforced biobased epoxy resins. Biolaminates are attractive to various industries because they are low-density, biodegradable, and lightweight materials. Natural fibers such as Ixtle, Henequen, and Jute were used as reinforcing fabrics for two biobased epoxy resins from Sicomin®. The manufacture of the biolaminates was carried out through the vacuum-assisted resin infusion process. The mechanical characterization revealed the Jute biolaminates present the highest stiffness and strength, whereas the Henequen biolaminates show high strain values. The rigid and semirigid biolaminates obtained in this work could drive new applications targeting industries that require lightweight and low-cost sustainable composites.

Résumé :
This article presents an ethnographic description of the artisanal production of maguey fiber in Indigenous hñähñu localities of the Mezquital Valley in the state of Hidalgo, Mexico. From an ethnobotanical perspective, that considers the physical characteristics of the fibers, a description is provided of the selection and extraction process, the preparation of the leaves before the defibration process, the defibration process itself, and the subsequent treatment of the ixtle (maguey fiber), as well as the carding techniques. Results show that both the selection process (species, variant, age of the leaf, and its central or marginal location) and the preparation of the fiber itself are variable but firmly rooted in local traditional ecological knowledge that corresponds with the required physical characteristics of length (cm), thickness (µm), linear density (dtex), tensile strength (N), and color of the fibers for textile production.

Résumé :
Abstract In the present work the carbon footprint for a material developed in the Faculty of Architecture, Design and Urbanism of the Autonomous University of Tamaulipas (UAT) constituted by argillaceous earth, aloe juice and fiber of ixtle with utility like the inner coating of walls in buildings was determined. The objective of this paper is the calculation of the contribution of carbon dioxide (CO2) by the plant, considering the stoichiometry of CO2 absorption accompanied by the determination at the laboratory level. It was found that the use of organic materials in mortar mixtures, when they are produced manually by the person who will use them, and that is common in cases of self-construction, can generate approximately −0.45 kg of CO2 equivalent for each kilogram of plant produced for the preparation of mixtures. In addition, the equivalent CO2 was calculated for the elaboration of a cubic meter of useful mixture as a wall covering obtaining a value below the equivalent 14 kg of CO2.

Résumé :
Reinforced polymeric composites with natural fibers have garnered significant interest in recent years due to the need for biomass utilization and the requirements of various industries, such as automotive and construction. Among these natural fibers, Agave lechuguilla fiber, commonly known as ixtle (FIx) or Tampico fiber, exhibits important characteristics such as length, high strength, and durability. However, there is limited literature on its conditioning, functionalization, and utilization as a reinforcing material in polymeric composites (CP). This study presents the optimization of the alkali-silane treatment of FIx, identifying the most suitable reaction conditions to enhance their thermal stability, tensile strength, and silane coupling agent (ACSi) grafting on the fiber surface. The chemical treatment with ACSi proved highly effective, resulting in a significant grafting content, which was confirmed through FTIR and SEM–EDS analyses. The high level of functionalization did not compromise the mechanical performance of the fibers, suggesting that functionalized FIx holds great potential as a reinforcing material in CP. These findings open new paths for the sustainable use of Agave lechuguilla fibers, contributing to the development of environmentally friendly and high-performance polymeric composites in various industrial applications.

Résumé :
Theories of writing are one of the fundamental ways by which Indigenous peoples have been labeled as "uncivilized." In these discussions, writing becomes synonymous with history, literacy, and often times Truth. As such, scholars studying Nahua codices and Andean khipu sometimes juxtapose the two because together they present a break in an evolutionary theory of writing systems that links alphabetic script with the construction of "complex civilizations." Contemporary scholars tend to offer an "inclusive" approach to the study of Latin American histories through challenging exclusive definitions of writing. These definitions are always informed and limited by language-the extent to which these "writing" systems represent language. However, recentering discussions of writing and language on what Gregory Cajete has called Native Science shifts the discussion to matters of ecology in a way that intersects with current scholarship in bicocultural diversity studies regarding the link between language, culture, and biodiversity. Because of the ways in which language configures rhetoric and writing studies, a shift in understanding how language emerges bears great impact on how we understand not only the histories tied to codices and khipu but also how they function as epistemologies. In my dissertation, I build a model of relationality using Indigenous and decolonial methodologies alongside the Nahua concept of in ixtli in yollotl (a wise face/a wise heart) and embodied rhetorics. The model I construct here offers a path for understanding "traditional" knowledges as fluid and mobile. I specifically look at the relationship between land, bodies, language, and Native Science functions on the reciprocal relationship between those three components in making meaning. I then extend this argument to show how the complex web of relations that we might call biocultural diversity produces and is produced by "things" like images from codices and khipu that in turn help to (re)produce biocultural diversity. Thing theory, in emerging material culture studies, argues for the agency of cultural artifacts in the making of various realities. These "things" always-already bear a relationship to bodies and "nature." Thing theory, then, can challenge us to see artifacts like khipu and Nahua images as language artifacts and help us connect Nahua images and khipu to language outside of a text-based model. Ultimately, I argue that Native Science asks us to see language as a practice connected to biocultural diversity.

Résumé :
Today, there is a growing need for alternative construction technologies that allow, among other things, to reduce of plastic waste and energy consumption during the life cycle of buildings. In this context, this article presents the partial results of a research project whose objective is to develop an innovative solution for plasterboard with plastic aggregates such as pet and Ixtle natural fibers. This solution is based on a plasterboard made with a mixture of eco-efficient composite materials. The composite material used in the production of the plates or panels results from the combination of two industrial by-products: commercial plaster; crushed or laminated pet, and natural “ixtle” textile fibers resulting from the “carving” process of the maguey leaves. In addition to the raw materials, the innovation of the solution also results from new future proposals for experimentation with different recycling materials. In this work, details of the process of elaboration of the plates and both the optimization of the composition of the material and the construction technology are provided, within the long strategies, the tests and validation of the mixtures will be carried out for the elaboration of plates from the point of view of mechanical, thermal and acoustic behavior, which from the results obtained can be concluded in the feasibility that meets all the structural stability requirements suitable for this type of construction element.
