The invention discloses a thermoplastic composite board and application thereof.The thermoplastic composite board comprises a laying layer structure formed by hot-pressing and compositing a reinforcing layer and a blocking layer, and the reinforcing layer is made of a one-way prepreg sheet formed by pressing and forming one-way continuous fibers after being subjected to melt impregnation through thermoplastic resin; and the barrier layer is made of a modified polyolefin resin film and/or a multiphase resin film. The barrier layer made of the modified polyolefin resin film and/or the multi-phase resin film is adopted to replace aluminum foil to prepare the thermoplastic composite board, the material cost is reduced, the interfacial compatibility between the barrier layer and the resin layer is good, the difference of thermal expansion coefficients is small, glue is not needed for bonding, direct press-fit forming can be achieved, and the interlayer peel strength of the composite board is obviously improved.
本发明公开了一种热塑性复合板及其应用,所述热塑性复合板包括由增强层和阻隔层热压复合而成的铺层结构,所述增强层是由单向连续纤维经过热塑性树脂熔融浸渍后再压制成型的单向预浸片制成,所述阻隔层由改性聚烯烃树脂膜和/或多相树脂膜制成。本发明采用由改性聚烯烃树脂膜和/或多相树脂膜制成的阻隔层替代铝箔制备热塑性复合板,降低了材料成本,阻隔层与树脂层之间的界面相容性好,热膨胀系数差异小,无需使用胶水粘接,可直接压合成型,复合板的层间剥离强度明显提高。
