摘要/Abstract

摘要： 采用真空辅助成型技术(VARI)制备不饱和聚酯为基体的苎麻/玻璃纤维混杂增强复合材料。通过改变层间混杂的铺层方式以及改变两种纤维的相对含量对比其力学性能,从而得到以上两种因素对力学性能的影响方式。结果表明,在相同的混杂比下,层间夹芯混杂(玻璃纤维在壳层,苎麻纤维在芯层)铺层的力学性能优于层间夹芯混杂(玻璃纤维在芯层,苎麻纤维在壳层)铺层,而层间交替混杂铺层的力学性能介于两者之间;在相同的铺层方式下,苎麻纤维相对含量与复合材料力学性能存在负相关关系,其中与拉伸性能呈现线性(一次函数)关系,与弯曲性能呈现三次函数关系。

Abstract: Unsaturated polyester-based composites reinforced with ramie fiber and glass fiber was prepared by Vacuum Assisted Resin Infusion (VARI) process. Different kinds of hybrid composites were studied. It was found that the sandwich structure which glass fiber as shell and ramie fiber as core (GRUP) has better mechanical properties than the sandwich structure which ramie fiber as shell and glass fiber as core (RGUP) in the same hybrid ratio. And, the mechanical properties of the interplay hybrid composite (IPUP) are between the two kinds of composites. Different hybrid ratios under the same sandwich structure were studied. It was found that the content of ramie fiber and the mechanical properties are negatively related. The relationship between the content of ramie fiber and the tensile strength as well as the tensile modulus follows a linear function, while the flexural strength and modulus are complied a cubic curve with the content of ramie fiber.

Key words: hybrid composites, unsaturated polyester, ramie fiber, mechanical property
