The invention discloses a large-thickness fiber reinforced composite material filled sandwich panel, and relates to the field of composite materials, and the large-thickness fiber reinforced composite material filled sandwich panel structurally comprises an upper layer panel, a lower layer panel, a middle rib plate and a filling material. According to the large-thickness fiber reinforced composite material filled sandwich panel for the ship, a traditional steel plate frame structure can be replaced, and the composite material plate can have high-strength compression resistance and bending resistance by optimizing the thickness of the rib plates, the thickness of the panel, the arc transition radius of the rib plates, the number of the clamping ribs and the bonding length of the rib plates and the panel; meanwhile, the excellent comprehensive performance of high modulus, high specific strength, light weight, high strength, wave transmission, vibration isolation, no magnetism, corrosion resistance and the like is achieved, and therefore the requirements for the strength and special functions of a main bearing structure of a ship are met.
本发明公开了一种大厚度纤维增强复合材料填充夹芯板,涉及复合材料领域,所述大厚度纤维增强复合材料填充夹芯板结构包括上层面板、下层面板、中间夹筋板和填充材料构成。本发明船舶用大厚度纤维增强复合材料填充夹芯板,可替代传统的钢制板架结构,通过优化筋板厚度、面板厚度、筋板圆弧过度半径、夹筋数量、筋板与面板粘接长度,能够使复合材料板具有高强度的抗压和抗弯能力,同时具有高模量、高比强度、轻质、高强、透波、隔振、无磁、耐腐蚀等优异的综合性能,从而满足船舶主要承载结构的强度及特殊功能要求。
