Effect of Temperature on Mechanical Properties of Epoxy Resin Matrix Composite Foams
空心玻璃微珠/环氧树脂(HGM/EP)作为保温隔热材料,在极端温度下的服役状态非常重要.采用注模成型法制备了HGM/EP复合材料,分别在20、40、60、80℃温度下对不同HGM填充量的复合材料进行准静态压缩实验,测定了压缩强度、弹性模量等力学参数,并结合SEM对其破坏形貌与机理进行分析.结果表明:适当添加HGM可以提高HGM/EP复合材料的力学性能.当HGM填充量为50%时,HGM/EP的压缩强度最大为46.3 MPa.HGM填充量为70%时,…查看全部>>
Hollow glass microsphere/epoxy resin(HGM/EP),as a thermal insulation material,is very important in the service state under extreme temperatures.HGM/EP composites were prepared by injection molding method.Quasi-static compression experiments were carried out at 20,40,60,80℃respectively for composites with different HGM filling amount.Mechanical parameters such as compressive strength and elastic modulus were determined,and the failure morphology and mechanism…查看全部>>
