The invention discloses a compounded automobile cab sleeping berth plate and a preparation method, and belongs to the technical field of automobile manufacturing and polymer composite materials. The sleeping berth plate is a composite material formed by hot pressing or cold pressing of honeycombs and prepregs, metal blocks or wood blocks are pre-buried in places needing screw fastening and punching, and after cutting, fireproof edge sealing strips are used for edge sealing on the end faces to form the product. The bending strength of the product can reach 70 MPa, the bending force can reach 1500 N, the bending elastic modulus can reach 5000 N/mm<2>, and the bearing pressure can reach 7000 N. The whole weight of the sleeping berth plate is only 1/3 of that of a common sleeping berth plate,and the sleeping berth plate has the advantages of light weight, high strength, fire resistance, flame retardance, sound insulation, noise reduction, damping and the like, and is simple in preparationmethod and high in production efficiency.

    本发明一种复合而成的汽车驾驶室卧铺板及制备方法,属于汽车制造、高分子复合材料技术领域;该卧铺板是由蜂窝和预浸料经热压或冷压而成型的复合材料,在需要螺丝紧固和打孔的地方预埋金属块或木块,再经裁切后,在端面用防火封边条进行封边而形成产品。该产品的弯曲强度可达70兆帕,弯曲力可达1500N,弯曲弹性模量可达5000N/mm2,承压力可达7000N。而整体重量只是普通卧铺板的1/3,该产品除了质量轻,强度高,还具有防火阻燃、隔音降噪、阻尼减震等优点,制备方法简单,生产效率高。
