碳纤维（CF）的市场需求逐年增长。因此，由于碳纤维增强塑料（CFRP）废料的数量不断增加，碳纤维增强塑料制造商正试图通过更加关注生态和经济因素来开发和设计材料和产品。在本报告中，将具有不同力学性能的再生CF （rCF）品种进行混合，以确定rCF在未来结构材料中应用的可能性。研究了1、3、5、8和10 MPa的合适压缩成型压力。建议设置在5 ~ 8mpa之间。混合不同的rCF可以控制材料的力学性能，这对当前的rCF应用有价值。采用修正混合规则（ROM）来讨论抗弯模量和抗弯强度。给出了不同rCF下的ROM系数。
Market demand for carbon fiber (CF) increases annually. Therefore, owing to the growing amount of carbon fiber-reinforced plastic (CFRP) waste, CFRP manufacturers are attempting to develop and design materials and products by paying greater attention to ecological and economic factors. In this report, recycled CF (rCF) varieties with differing mechanical properties are mixed to determine the possibility of rCF application in future structural materials. 1, 3, 5, 8 and 10 MPa are investigated for proper compression molding pressure. The range of 5–8 MPa is recommended. Mixing different rCFs can control the mechanical properties of the material, which is valuable for current rCF applications. A modified rule of mixture (ROM) is used to discuss flexural modulus and flexural strength. The coefficients for ROM are given for different rCF.
