缝合制备有机硅复合材料及其弯曲性能研究
Fabrication and bending property of stitched silicone composite
摘要
Abstract
The influence of stitched process on the flexural strength of vycor fiber/silicone composites was studied. It is showed that the flexural strength of composite fabricated by two processes is nearly identical at room temperature. The property of composite fabricated by stitched process is obviously higher than that of the unstitched one after treated at 500℃ for 10 min. Instead, the property of composite fabricated by stitched process is lower than that of the unstitched one after treated at 700℃ for 10 min. The results show that the stitched process can effectively prevent the delamination of composites below 500℃. But the property of composites becomes worse with the degradation of PBO fibers at higher temperature. The flexural strength of composite is lower than that of unstitched ones at 700℃.ess关键词
