汽车涂层飞石冲击测试及评价方法研究

Research of Auto Coating Chips Resistance Test & Evaluation System

文章介绍了目前国际上检测汽车涂层耐飞石冲击性能的两种常用试验和评价体系,并对比了其主要区别。然后进一步通过实验研究了实验样品角度、试验温度及石子用量对试验结果的影响。最后比较了各个主机厂汽车涂层飞石冲击试验的区别,分析了各个标准的优缺点,并对试验标准的制定提出了建议。

The two major auto coating chips resistance test ＆ evaluation systems are introduced and compared. Further, the specimen angle, test temperature ＆ the test stones volume are investigated by examinations. At last, the advantage ＆ disadvantage of different OEM＇s chips resistance test ＆ evaluation method is analyzed. Then, the advice of auto coating chips resistance standard is brought forward.
