The invention discloses a fiber-reinforced resin-based composite board, a composite board component and a preparation method.The fiber-reinforced resin-based composite board comprises a first preformed body and a second preformed body, and the first preformed body and the second preformed body are matched to form a hollow structure with a cavity; the first preformed body and the second preformed body are formed by laying fiber prepregs layer by layer in different directions, so that fibers in the first preformed body and the second preformed body are distributed in different directions. According to the fiber-reinforced resin-based composite board prepared by adopting a two-step method, the porosity in the composite board can be greatly reduced, the fibers are in a straightened arrangement state, and the bearing performance or mechanical performance of the fiber-reinforced resin-based composite board is superior to that of a laminated board, a plate rib structure composite board and a pultrusion hollow structure composite board under the same thickness. The problem that in the prior art, bearing capacity, light weight and sound insulation performance of a plate, especially a vehicle body plate are difficult to consider at the same time is solved.
本发明公开了一种纤维增强树脂基复合板、复合板材构件及制备方法,纤维增强树脂基复合板包括第一预成型体和第二预成型体,所述第一预成型体和所述第二预成型体配合形成具有腔体的中空结构,所述第一预成型体和所述第二预成型体为纤维预浸料朝不同方向层层铺设而成,使得所述第一预成型体和所述第二预成型体中的纤维沿不同方向分布。本发明采用两步法制备的纤维增强树脂基复合板可大大降低复合板中的孔隙率,且纤维处于伸直排列状态,同等厚度下其承载性能或力学性能优于层合板、板筋结构复合板和拉挤成型空心结构复合板。本发明解决了现有技术中板材尤其是车体板材承载力、轻量化和隔声性能难以同时兼顾的问题。
