硅橡胶热膨胀法成型复合材料制件的研究

Study on the Silicon Thermal Expansion Method to Prepare Composite Parts

探讨了硅橡胶热膨胀法成型复合材料制件的原理及工艺特点。首先测试了硅橡胶的热老化稳定性,通过最简单的平板式试验件验证了该工艺方法,进一步在不同的工艺间隙下制得了不同质量的复合材料盒段。结果表明,工艺间隙决定复合材料制件的质量,而且工艺间隙具有可调性。

The principle and process of the silicon rubber thermal expansion method to prepare composite part were studied. Firstly, the thermal ageing stability of silicon rubber was tested, then flat composite panel, which was the simplest structure, was produced by this technology. Composite boxes of different quality were manufactured at different process gap. It was found that the quality of composite panel was determined by the process gap, which could be adjusted by trial to get composite part meeting requirement.
