Abstract

Hemp wood core (HWC) filled Si-containing epoxyurethane biocomposites, in which diane epoxy resin was replaced with epoxidized soybean oil (ESO), were obtained. It was shown that the tensile strength of ESO-containing polymer was higher, and the flexural strength was lower than those of original polymer. HWC was especially effective strengthening filler for modified epoxyurethanes, because in that case mechanical properties of composites were higher than those of unfilled polymer matrices. Particularly, flexural and tensile strength of unfilled epoxyurethane with maximum content of ESO were 8.1 and 6.8 MPa respectively, while in corresponding composite they reached 17.3 and 15.7 MPa.
麻木芯增强环氧聚氨酯生物复合材料的物理力学性能
以环氧大豆油(ESO)代替环氧树脂,制备了麻木芯(HWC)填充硅基环氧聚氨酯生物复合材料。结果表明,含eso聚合物的拉伸强度比原聚合物高,而弯曲强度比原聚合物低。HWC是改性环氧聚氨酯特别有效的增强填料,因为在这种情况下,复合材料的力学性能高于未填充的聚合物基体。其中,ESO含量最大的未填充环氧丙烷的抗弯强度和抗拉强度分别为8.1和6.8 MPa,而相应复合材料的抗弯强度和抗拉强度分别为17.3和15.7 MPa。
