摘　　要：为了满足乒乓球体育器材对材料性能的高要求,对乒乓球体育器材用纤维增强塑料耐蚀强度进行测试研究,在不同环境状态下完成乒乓球体育器材用纤维增强塑料的质量变化率、强度保留率以及抗弯强度变化试验。试验结果表明:经过8%(质量分数)NaOH溶液浸泡后试件硬度的变化最大,经蒸馏水与4%(质量分数)NaC1溶液浸泡后硬度改变较小;8%(质量分数)NaOH溶液浸泡的已封边试样弯曲强度保持率最高,而该溶液浸泡的未封边试样弯曲强度保持率最低,达到25%;纤维增强塑料在室温状态下的耐碱性高于非室温状态,试样在放置14天左右时质量变化率、强度保留率以及抗弯强度变化最小,且封边后试样的耐蚀性能高于未封边的试样。由此可知,乒乓球体育器材用纤维增强塑料耐蚀强度强,耐碱性能高,封边处理可进一步提升其耐蚀性。In order to meet the high requirements of table tennis sports equipment for material performance,the corrosion resistance of fiber reinforced plastics for table tennis sports equipment was tested and studied.The weight change rate,strength retention rate and bending strength change test of fiber reinforced plastics for table tennis sports equipment were completed under different environmental conditions.The test results show that the hardness of the specimen changes most after soaking in 8%NaOH solution,and the hardness changes little after soaking in distilled water and 4%NaC1solution;The retention rate of the bending strength of the sealed edge specimens soaked in 8%NaOH solution was the highest,while the retention rate of the bending strength of the non sealed edge specimens soaked in this solution was the lowest,reaching 25%;The results show that the alkali resistance of FRP at room temperature is higher than that at non room temperature,and the weight change rate,strength retention rate and bending strength of the samples are the smallest when they are stored for about 14days,and the corrosion resistance of the samples after edge sealing is higher than that of the samples without edge sealing.It can be seen that the fiber reinforced plastic used for table tennis sports equipment has strong corrosion resistance and high alkali resistance,and the edge sealing treatment can further improve its corrosion resistance.
