Mechanical Strength of Bamboo Fiber Biocomposites Within a Biorefinery Concept

open in viewerA new approach to fiber pretreatment for a bamboo fiber-reinforced composite (BFRC) was utilized and its resultant biocomposites’ strengths were analyzed via tensile and flexural mechanical testing. Co-solvent enhanced lignocellulosic fractionation (CELF) is a biomass pretreatment process that separates cellulose from lignin and hemicellulose in a way that preserves the lignin and hemicellulose rather than destroying them. This allows for further valorization of these components and proves to be a more sustainable pretreatment process for BFRC fabrication. In an effort to make a more sustainable biocomposite, the team found that there was no statistically significant data to prove that incorporation of CELF-treated fibers was more effective than raw bamboo fibers, concluding that CELF-treated fibers performed no worse than the bamboo fiber and epoxy counterparts. Tensile and flexural results were converted to specific strengths and compared to a common building material, 304 stainless steel. The CELF fiber composites’ maximum tensile strength performed at 43.8% of 304 steel, and the maximum flexural strength was found to be 261.1% of 304 steel. It was found that limitations to the strengths of the biocomposite samples arose from random, discontinuous fiber alignment and incomplete degasification of the epoxy resin. Incorporation of a bio-based epoxy in an effort to promote greater sustainability of a biocomposite is suggested for future improvement upon the bamboo fiber reinforced composites fabricated in this study.
