摘　　要：　介绍了碳纤维增强塑料(CFRP)异形杆的一种新的成型方法,采用了聚全氟乙丙烯(FEP)热收缩管封装技术,使CFRP杆件的外表面光亮圆滑,实现了近似无余量成型,同时通过铺层设计和成型工艺控制,使支撑杆轴向线膨胀系数达到1 2×10-6K-1,满足了设计小于1 5×10-6K-1的要求,大大提高了支撑杆的尺寸稳定性。The new moulding technology of CFRP profiled pole was introduced.The surface of CFRP pole was bright and smooth and approximately no remainder moulding was achieved by using FEP heat\|shrinkable tube encapsulation technology.The axial line expand coefficient of knighthead reached to 1.2×10-6K-1,which met the design demand by means of lay\|up designing and moulding technique control.The dimension stability of knighthead was greatly improved.
