The invention provides a composite sandwich panel as well as a preparation method and application thereof. The preparation method of the composite sandwich panel comprises the following steps: heatinga glass fiber reinforced plastic plate at different upper and lower surface heating temperatures; stacking the heated glass fiber reinforced plastic plate, a polystyrene foam plate and the heated glass fiber reinforced plastic plate in sequence to obtain a combined material; and carrying out compression molding on the obtained combined material to obtain the composite sandwich plate. The preparation method disclosed by the invention is simple to operate, environment-friendly, low in cost and high in production efficiency, is beneficial to industrial large-scale production, and has a relatively good industrial application prospect.
本发明提供了一种复合夹层板及其制备方法和用途,所述复合夹层板的制备方法包括:将玻璃纤维增强塑料板进行加热,上下表面加热温度不同;按照加热后的玻璃纤维增强塑料板、聚苯乙烯泡沫板和加热后的玻璃纤维增强塑料板的顺序依次叠放,得到组合材料;将得到的组合材料进行模压成型,得到复合夹层板。本发明所述制备方法操作简单,环境友好,成本低,生产效率高,有利于工业化规模生产,具有较好的工业应用前景。
