摘要
具有透明特性的PC材料可以用来替代汽车前后三角窗及后挡风玻璃。三角窗在原则上要求设计成壁厚一致,以避免色散和成像扭曲等问题;在模具设计上,浇口位置设计的合理性能有效避免应力集中现象;同时PC材料三角窗表面需要进行硬涂层处理,增强耐刮擦性能,并提高相应的耐候性。PC材料设计的三角窗,能有效降低重量,对汽车的轻量提供贡献,是未来发展的趋势。
With transparent PC material properties can be used to replace the front and rear quarter glass and rear window glass. In order to avoid dispersion and image distortion program, wall thickness should be consistent in design, The gate location design reasonable performance effectively avoid stress concentration phenomenon in mold design; At the same time in order to strengthen the scratch resistance and improve the corresponding weather ability, PC material quarter glass need to hard coating surface treatment. The engineering plastics PC of quarter glass is helpful the body lightweight and the tendency of future development.
