一、前言由于玻璃纤维增强塑料(GRP)采用的是与温度相关性较大的塑料作为基体材料,因此,当它作为结构部件在比较高的温度下使用时,其力学性能是要降低的。为了进一步扩大玻璃纤维增强塑料作为结构的使用范围,必须了解玻璃纤维增强塑料对应于环境温度变化的力学性性能及其极限值。另外,对使用玻璃纤维增强塑料的结构设计来说,除了按传统设计把强度作为基础以外,还要求把刚性也考虑进去的更合理的设计。因此,采用高温性能优良的基体材料是很必要的,温度对通用的玻璃纤维增强塑料材料特性的影响,主要有疲劳特性、蠕变特性等基本性能。
I. INTRODUCTION Since glass fiber reinforced plastic (GRP) uses a plastic material that is highly dependent on temperature as a base material, its mechanical properties are reduced when it is used as a structural component at relatively high temperatures. In order to further expand the use of glass fiber reinforced plastic as a structure, it is necessary to understand the mechanical properties of glass fiber reinforced plastics corresponding to changes in ambient temperature and their limits. In addition, structural design using glass fiber reinforced plastic, in addition to the traditional design based on the strength, but also requires more reasonable design to take into account the rigidity. Therefore, the use of high-temperature performance of the matrix material is necessary, the temperature of the common glass fiber reinforced plastic material properties, mainly fatigue properties, creep properties and other basic properties.
