T型壁板RFI缝合复合材料的屈曲性能

Buckling performance of T-shape RFI stitched composites panel

在实验研究BS3-94-10型环氧树脂膜流变学性能、叠层预制件厚度方向压实性能、RFI缝合随炉试件层间剪切和弯曲性能的基础上,优化设计了树脂膜融渗及缝合工艺参数,并制备了高性能T型壁板RFI复合材料制件。缝合前后T型壁板屈曲性能测试结果表明,缝合可显著提高T型壁板的屈曲性能。

An experimental study of the rheology behavior of BS3-94-10 type epoxy resin film, the compactibility of the pre-fabricated laminate and the inter-laminate shearing and bending properties of the coupon of RFI stitched composite were carried out, and the optimal technical parameters of resin film infusion and stitching process were designed. On this basis, high performance T-shape composites panels were fabricated. The buckling performance of the T-shape composites panels before and after stitching was tested. The results show that stitching can significantly improve their buckling performances.
