The invention discloses a variable-density thermoplastic composite material sandwich structure as well as a preparation method and application thereof, and belongs to the technical field of composite materials. The thermoplastic composite sandwich structure comprises panels and a variable-density sandwich layer located between the panels, continuous fiber fabric reinforced thermoplastic resin plates are used as the panels, expanded long fiber reinforced thermoplastic resin sheets are used as the variable-density sandwich layer, and the thermoplastic composite sandwich structure is obtained through hot-pressing curing and then cold-pressing shaping under the heating and pressurizing conditions. The thermoplastic composite material sandwich structure disclosed by the invention has the characteristics of light weight, variable density, safety and environmental protection, and can be applied to occasions such as automobile interiors, bus roofs or notebook computer rear covers.

    本发明公开了一种可变密度的热塑性复合材料夹芯结构及其制备方法和应用,属于复合材料技术领域。该热塑性复合材料夹芯结构包括面板和位于面板之间的可变密度夹芯层,以连续纤维织物增强热塑性树脂板材作为面板,以膨胀化的长纤维增强热塑性树脂片材作为可变密度夹芯层,在加热加压的条件下热压固化后冷压定型得到。本发明的热塑性复合材料夹芯结构具有轻量化、可变密度和安全环保的特性,可用于汽车内饰、公交车顶板或笔记本电脑后盖等场合。
