Continuous fiber enhanced thermoplastic foaming plate for passenger coach roof and preparation method thereof

The invention provides a continuous fiber enhanced thermoplastic foaming plate for a passenger coach roof. The foaming plate comprises a surface layer with a decorative pattern, a foaming core layer and a continuous fiber enhanced thermoplastic composite sheet material. The continuous fiber enhanced thermoplastic foaming plate provided by the invention has the beneficial effects that the product has the advantages of high mechanical strength, light weight, good heat-resisting performance, low VOC (Volatile Organic Compounds) and the like; disadvantages of the roof in a passenger coach that theweight is heavy, the thermal deformation is serious, the rigidity is poor and the like are effectively solved. Meanwhile, the product meets the requirements of low cost, environment protection, lightweight, recyclability and the like. 种客车顶板用连续纤维增强热塑性发泡板，该发泡板包括具有花纹的面层、发泡芯层、连续纤维增强热塑性复合片材。本发明有益的效果是：产品具有机械强度高、重量轻、耐热性能好、低VOC等优点，有效解决了客车内顶板存在的重量高、热变形严重、刚性差等诸多不足。同时产品兼顾成本、环保、轻量化、可回收等要求。
