What is Development of a Reinforced Styrene-free Unsaturated Polyester Composite Based on Bamboo Fibers about?

Bamboo fibers (BFs) are abundant but underutilized as reinforcing fibers in wood plastic composites (WPCs). BFs were investigated as reinforcing fibers for unsaturated polyester (UPE) composites (BF-UPE). The UPE was prepared from condensation polymerization of propylene glycol (PG), isophthalic acid (IPA) and maleic anhydride (MA). Acrylated epoxidized soybean oil (AESO) was used instead of styrene which is usually applied as a diluent in most of the commercial UPE resins. The properties of BF-UPE were compared with those of kenaf fibers-UPE (KF-UPE). BF-AESO-UPE composites had tensile strengths (TSs), which were comparable to those of BF-styrene-UPE composites, while their flexural strength (FS) and impact strength (IS) were higher than those of BF-styrene-UPE composites. The glass transition temperature (T g ) of BF-AESO-UPE composites was lower than that of BF-styrene-UPE composites. BF-AESO-UPE composites had lower TS than KF-AESO-UPE composites, while their FS was comparable to that of KF-AESO-UPE composites.
