摘　　要：研究了大尺寸复合材料水滴形截面异型构件的成型工艺。在达西定律的基础上采用实验法测得了玻璃纤维织物渗透率,建立了树脂浸润过程的仿真模型。采用仿真软件对典型构件一体成型充模过程进行仿真分析,分别对中心点注射、中心线注射、单边注射和多线程接力注射方案进行探讨,仿真结果表明,多线程接力注射方案可有效缩短充模时间,满足树脂适用期内完成充模的要求,并达到100%充模率。采用多线程接力注射方案制备了典型构件样机,实际充模时间与理论计算相差约10%,对生产实践具有指导性意义。This paper studied the manufacture of the FRP rudder skin.The permeability test and resin gel test of glass fiber fabric were carried out;the filling process of composite rudder surface was simulated by PAM-RTM software.The central point injection,central line injection,single side injection and multi-thread relay injection were discussed,the simulation results show that,the multi-thread relay injection scheme can satisfy the requirement of filling the mold in the resin using time,and achieve 100%filling rate.The prototype of composite rudder was fabricated by multi-thread relay injection.The actual filling time was about 10%different from the theoretical calculation.
