M40/5228复合材料力学性能研究

Study on Mechanical Properties of the M40/5228 Composites

用湿法缠绕技术制作了Ｍ４０／５２２８预浸料， 对热压罐固化的Ｍ４０／５２２８复合材料的室温、高温干态和湿态力学性能进行了研究， 用扫描电镜 （ＳＥＭ） 对复合材料的界面进行了表征。与Ｍ４０／４２１１复合材料相比， Ｍ４０／５２２８复合材料的各项力学性能均有很大程度的提高。Ｍ４０／５２２８复合材料具有优异的耐湿热性能， 在１３０℃干态和湿态下， 其弯曲强度。

The mechanical properties of M40/5228 composites were investigated under the several conditions The interface of the composites was characterized by SEM Compared with M40/4211 composites, M40/5228 composites possesses more excellent mechanical properties M40/5228 composites has excellent hygrothermal property, while the retention of the flexural properties and shear property is higher than other several composites under the conditions of dry and wet at 130℃
