玻璃钢/复合材料属于粘弹性材料,在室温条件下就存在蠕变现象。为研究这类材料的粘弹性特性和提供受长期静载作用产品的设计数据,需研究材料的蠕变性能。正如常规力学测试那样,玻璃钢/复合材料的蠕变也分为拉伸、压缩、弯曲、剪切和复合抗力试验。要研究材料的蠕变性能,首先遇到的问题是试验设备的建立,进行该课题研究所需的试验机数量比较多,甚至要数十台,其费用之大可想而知。在国外有现成的蠕变机,也有自行设计的
FRP / composite materials are viscoelastic material, there is creep phenomenon at room temperature. To study the viscoelastic properties of such materials and to provide design data for products that are subject to long-term static loading, the material’s creep properties need to be investigated. As with conventional mechanical testing, FRP / composite creep is also divided into tensile, compressive, flexural, shear and composite resistance tests. To study the creep properties of materials, the first problem encountered is the establishment of test equipment, the number of test machines required for the study of this subject is relatively large, or even dozens of units, the cost can be imagined. There are ready-made creep machines abroad, but also have their own design
