OPTIMIZATION OF THE PULTRUSION PROCESS PARAMETERS OF CFRP PLATES
-
摘要: 利用Taguchi方法,研究多个拉挤工艺参数(如模具温度、拉挤速率等)、树脂种类及纤维含量等对制备的碳纤维增强树脂基复合材料(CFRP)板材力学性能的影响,并利用优化的拉挤工艺参数,制备高力学性能的CFRP板材。结果表明:纤维含量、环氧树脂种类、牵引速率和模具温度是影响CFRP拉挤板材力学性能的主要因素,而后固化温度、纤维张力的影响较小,胶槽温度的影响可以忽略不计。Abstract: The pultrusion process parameters having influence on the mechanical properties of CFRP plates based on Taguchi method and the optimal pultrusion process parameters for producing CFRP plates with high mechanical properties are studied.The results show that fiber content, epoxy resin types, draw rate and mold temperature are the main factors influencing the mechanical properties of CFRP plates, post-curing temperature and fiber tension have less influence, the influence of glue tank temperature can be neglected.
