摘　　要：采用自行设计的模具,对双层玻璃纤维增强聚丙烯(GFRTP)复合材料单向层合板进行了半球形非等温拉伸成型试验,结合显微观察等手段,就复合材料单向层合板预热温度、拉伸速率等对制件厚度分布、成型质量的影响进行了研究。结果表明,提高预热温度可导致制件变薄;提高拉伸速率可改善制件的表面质量,当拉伸速率超过150 mm/min时制件会产生拉裂和脱层的缺陷。A self-designed mold was used to conduct hemispherical non-isothermal deep drawing tests for the double-layer glass-fiber-reinforced polypropylene composite unidirectional laminates.The effects of preheating temperature and drawing speed of composite unidirectional laminates on the thickness distribution and forming quality of the part were investigated through microscopic observation and other methods.The results indicated that an increase in preheating temperature resulted in the formation of the thinner laminates.The surface quality of the laminates was improved with an increase in drawing speed.The laminates presented cracks and delamination defects with a drawing speed of over 150 mm/min.
