四种生物基热固性材料被用作制造具有高性能和生物基含量的天然纤维增强生物复合材料的基体。热固性材料包括丙烯酸酯化环氧大豆油（AESO）、具有甲基丙烯酸酯化异山梨醇（MI）作为共聚单体的AESO（MI-AESO）、具有MI的甲基丙烯酸酯化AESO（MI-MAESO）和MI树脂。竹纤维（BFs）和大麻纤维（HFs）被选为生物复合材料中天然纤维的代表。通过对纤维和树脂的特性分析以及对复合材料的密度、弯曲性能、动态力学性能和吸水率的测量，揭示了纤维类型和树脂组成对复合材料的协同效应。结果表明，树脂的组成，化学结构和基质的交联密度与生物基热固性材料的性能密切相关，因此产生的生物复合材料。HF增强复合材料实现了更上级的弯曲强度，弯曲模量，和耐水性比BF增强复合材料。
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.
