The invention relates to a fireproof composite material deck which is composed of a foam sandwich and composite material skin layers arranged on the upper side and the lower side of the foam sandwich. The composite material skin layer comprises a fiber pouring layer and a hand lay-up layer. In implementation, the mode that the hand lay-up layer and the pouring layer are combined is adopted on the upper portion and the lower portion of the foam sandwich respectively, so that the upper surface and the lower surface of the composite material deck are both provided with efficient flame-retardant filler, the oxygen index of the composite material deck is larger than or equal to 36, and if the oxygen index is generally larger than or equal to 32, the composite material deck belongs to a flame-retardant material; and meanwhile, the ratio of the accelerant in the hand lay-up layer is relatively low, so that the pre-curing of the resin in the hand lay-up layer in the laying and pouring molding process can be effectively prevented, and the product quality is improved.
本发明涉及一种防火复合材料甲板,防火复合材料甲板由泡沫夹心和设在泡沫夹心上、下两侧的复合材料蒙皮层组成;复合材料蒙皮层包括纤维灌注层和手糊层。实施中,在泡沫夹心的上、下分别采用手糊层和灌注层相结合的方式,使得复合材料甲板的上、下表面都带有高效阻燃的填料,使得复合材料甲板的氧指数大于等于36,一般氧指数大于等于32就属于难燃材料,使得复合材料甲板遇火时拥有更好的阻燃性能,同时本发明的手糊层中促进剂比列较低,能有效防止铺设及灌注成型过程中手糊层树脂提前固化,提高了产品的质量。
