摘要整理
近年来，环境问题促使全球工程领域（包括高分子工程和复合材料制造）采取可持续发展措施并践行循环经济。织物增强热塑性复合材料（FRTPs）作为更环保的解决方案得到推荐。同时，利用回收碳纤维（rCF）等回收增强相也引起广泛关注。本研究旨在评估丙烯酸基热塑性复合材料（采用Arkema公司Elium®树脂）的性能。采用真空辅助树脂传递模塑工艺，分别以原生织造碳纤维（vCF）和非织造回收碳纤维（rCF）织物作为增强体制备复合材料。优化的基体配方表现出5 GPa的弯曲模量和78 MPa的弯曲强度。采用织造原生碳纤维制备的复合材料弯曲模量和强度分别达到36 GPa和620 MPa。非织造织物的研究具有特殊意义，因为该纤维网由来自热固性复合材料报废件（EoL）的回收碳纤维组成。结果令人满意，弯曲模量达到8 GPa，弯曲强度为113 MPa。预期通过优化模塑工艺参数和条件可进一步改进性能。
