摘要 Four biobased thermosets were used as matrices for manufacturing natural fiber-reinforced biocomposites with high performance and biobased contents. The thermosets included acrylated epoxidized soybean oil (AESO), AESO with methacrylated isosorbide (MI) as a comonomer (MI-AESO), methacrylated AESO with MI (MI-MAESO), and MI resins. Bamboo fibers (BFs) and hemp fibers (HFs) were chosen as representatives for natural fibers in the biocomposites. The synergistic effects of fiber type and resin composition on the obtained composites were revealed through analyses of characteristics of the fibers and the resins as well as measurements of densities, flexural properties, dynamic mechanical properties, and water absorption of the composites. Results indicated that resin composition, chemical structure, and crosslinking density of the matrices were closely associated with the performance of the biobased thermosets and hence the resulting biocomposites. The HF-reinforced composites achieved much superior flexural strengths, flexural moduli, and water resistance than the BF-reinforced composites.
