Abstract

本发明涉及一种碳纤维异形结构件的成型方法，具体步骤包括：C型截面层压框的制备为由上模和下模合模形成C型截面的框型模具；C型截面对应框型模具环形模腔；在环形模腔中铺贴预浸料并固化形成C型截面层压框；复合钢网结构制备为在钢网周缘铺贴预浸料，形成预浸料包边的复合钢网结构，之后进行固化；将固化后的C型截面层压框与复合钢网结构粘结为一体，并进行热固成型得到复合材料异形结构件。本发明解决了厚壁窄腔管梁类复合材料构件铺贴时预浸料架桥，欠压，难以铺贴平整的问题，保证了产品的表面质量。

Description

一种碳纤维异形结构件的成型方法
技术领域
本发明属于复合材料成型技术，特别涉及碳纤维异形结构件的成型方法。
背景技术
钢网类复合材料构件通常通过一次性整体挡块成型。挡块之间为刚性接触，难以放置到位，无法满足零件的尺寸和位置度要求；零件在预压实时，压力无法传递到挡块下部，致使成型后的零件表面质量凹凸不平,难以满足零件外观质量要求，同时成型后的零件通常会有欠压、脱粘现象。钢网具有一定的刚性,复合材料在铺贴过程复合材料贴合之后容易再次被铜网撑开出现架桥现象。
发明内容
本发明的目的是：提出一种保证悬空框架式碳纤维类复合材料构件铺贴可操作性和外观质量的成型方法。
本发明的技术方案是：提供一种复合材料异形结构件的成型方法，包括C型截面层压框的制备和复合钢网结构制备；具体步骤如下：
C型截面层压框的制备为由上模和下模合模形成C型截面的框型模具；C型截面对应框型模具环形模腔；在环形模腔中铺贴预浸料并固化形成C型截面层压框；
复合钢网结构制备为在钢网周缘铺贴预浸料，形成预浸料包边的复合钢网结构，之后进行固化；
将固化后的C型截面层压框与复合钢网结构粘结为一体，并进行热固成型得到复合材料异形结构件。
进一步的，所述的预浸料为碳纤维预浸料或玻璃纤维预浸料。
进一步的，所述的C型截面层压框的制备和复合钢网结构制备为同时进行。
进一步的，所述的钢网为过滤网。
附图说明
图1为异形结构件的结构示意图；
具体实施方式
提供一种复合材料异形结构件的成型方法，包括C型截面层压框的制备和复合钢网结构制备；具体步骤如下：
C型截面层压框的制备为由上模和下模合模形成C型截面的框型模具；C型截面对应框型模具环形模腔；在环形模腔中铺贴预浸料并固化形成C型截面层压框；
复合钢网结构制备为在钢网周缘铺贴预浸料，形成预浸料包边的复合钢网结构，之后进行固化；
