摘　　要：相对于中碱玻璃纤维,无碱玻璃纤维由于成型温度高、硬化速度快、结构键能大等原因,而具有很高的拉伸强度,且耐老化性及耐温性性能好~[1],用于增强树脂砂轮后,砂轮的回转强度达到或超过国内国际标准;而中碱玻璃纤维由于其强度偏低,耐老化性能和耐温性能差,尤其当砂轮产品存放后其回转强度迅速下降,存在安全隐患,因此不能应用于砂轮增强。Compared with C-glass fiber, E-glass fiber has high tensile strength due to its high forming temperature,high hardening speed and high structural bond energy as well as high aging resistance and heat resistance. The rota- tional strength of resin-bonded grinding wheels reinforced with E-glass fiber can reach or exceed the domestic and international standards, while C-glass fiber can not be used for grinding wheels because of its low strength, poor ag- ing resistance and heat resistance, and paticularly the quick decrease of rotational strength after storage which cau- ses safety risks.

关 键 词：无碱玻璃纤维 中碱玻璃纤维 砂轮 回转强度.
