本文讨论了高强度可生物降解的“绿色”交叉铺层织物增强复合材料的发展。以机织马尼拉麻纤维为增强体，淀粉基乳液型生物降解聚合物为基体，制备了复合材料。复合材料的机械性能已被评估为纤维含量（20至75质量%）的函数。实验结果表明，复合材料的弯曲强度和拉伸强度分别为104MPa和153MPa。拉伸模量、弯曲模量和弯曲强度均随纤维含量的增加而增加。然而，拉伸强度随着纤维含量增加直到50质量%，并且此后保持恒定。这种对纤维含量的依赖性是由于在热压过程中引入的纤维损伤引起的纤维强度的降低。
This paper discusses the development of high-strength biodegradable, “green”, cross-ply fabric-reinforced composites. The composites were made using woven Manila hemp fibers as the reinforcement and starch-based emulsion-type biodegradable polymer as the matrix. The mechanical properties of the composites have been evaluated as a function of fiber content (20 to 75mass%). The experimental results indicate that the composites show the flexural and tensile strength of 104MPa and 153MPa, respectively. Both of tensile and flexural modulus and flexural strength increased with increasing the fiber content. However, the tensile strength increased with the fiber content till 50mass% and remained constant thereafter. This dependence on the fiber content is due to the decrease in fiber strength caused by fiber damages introduced during hot-pressing.
