“…Young's modulus and strength at break, comparable to those of petroleum-derived materials [14]. An interesting way of developing new flax-based composites has been to add polysaccharides from the seeds by impregnation method as a matrix to obtain "wholly flax" biocomposites [15,16]. The flaxseed polysaccharides are water-soluble complex polymers with a highly branched structure [17] able to stress transfer into the composite with a maximal value of Young's modulus (E) and tensile strength () for a 20% mucilage loading (w/w).…”

In the present work, an innovative range of foams, based on flax gum-filled epoxy resin was developed, reinforced or not by flax fibers. Foams and composites with different gum and epoxy resin contents were produced and characterized for mechanical and thermal performances. To enhance the organic flax gum filler's cross-linking, we exploited the oxidized components' reactivity with the amine hardener (isophorone diamine). We compared the materials obtained with those derived from the native components. Flax gum and fibers were primarily characterized by chemical analysis, NMR, and FTIR to evaluate the mild oxidation of native materials. The formation of chemical bonds between oxidized polymer chains, epoxy resin, and hardener has been evidenced by FTIR, and the materials were then studied by SEM, X-ray computed micro-tomography (CT), and submitted to mechanical and thermal tests. The relevance of oxidation treatment was highlighted, through a significant increase in density and mechanical performances (+36% and +81%, respectively for the 100% flax gum material). The positive effect of flax fibers on homogeneity evidenced through micro-CT analysis was also clearly addressed. This set of promising results paves the way for future development of fully flax-based insulation composite materials.

“…This plant leaves a large amount of waste from its pruning process, composed mainly of nopal cladodes. Therefore, this study focuses on the cladode’s two main components: the mucilage and the cladode fiber. , The mucilage is a gel-like substance found within nopal pads, which is rich in polysaccharides, and the cladode fiber is the remaining material of the nopal cladodes after the mucilage extraction. The mucilage exhibits unique chemical properties that can enhance the functionality of natural fibers …”
