摘要

针对977-2/IMS 预浸料在热压罐零吸胶工艺下采用H 型方式成型的Ⅰ型零件，分别采用标准固化制度及阶梯加压制度进行了树脂压力在线测试，基于测试结果，分析了树脂压力与罐压的等效性及硬模传压的均匀性，提出了实际零件硬模传压的测试制度参考。结果表明：单侧硬模传压区域的树脂压力在稳定后与罐压一致，验证了预浸料在热压罐零吸胶工艺下树脂压力与铺层压力的等效性；双侧硬模传压区域的树脂压力存在载荷平衡的过程，稳定后不同区域的树脂压力均匀并与罐压一致；与阶梯加压制度相比，标准固化制度下树脂压力在测试初期存在一定波动，稳定后两种工艺制度下的树脂压力一致，这为热分布差异相对较大零件的树脂压力测试提供了方法参考。

Abstract

For Ⅰ shape parts made by 977-2/IMS prepreg using H type molding in autoclave zero-bleeding process

resin pressure has been tested by using online standard curing cycle and step pressurization cycle respectively. The equivalence of resin pressure and autoclave pressure is investigated and the uniformity of pressure transfer with rigid mold is analyzed according to the resin pressure test results. The results indicate that the resin pressure is consistent with autoclave pressure in one side rigid mold area after stabilization. The equivalence of resin pressure and layer pressure in autoclave zero- bleeding process is verified. The resin pressure has a load balance procedure in two-side rigid mold. The resin pressure is even in different area and is consistent with the autoclave pressure. Compared with step pressurization cycle

the resin pressure has some fluctuations of the standard curing cycle in the initial stage of the test. However

the resin pressures under the two process cycles are the same after stabilization. It provides a reference for the resin pressure test of parts whose thermal distribution is relevant large different.
