The invention discloses an exterior part plate and a preparation method thereof, an exterior part and a forming process thereof, and a vehicle, and belongs to the technical field of vehicles. The core layer in the exterior part plate provided by the invention comprises the fibers and the resin matrix, and the fibers and the resin matrix are compounded, so that the rigidity and the strength of the exterior part plate can be enhanced, the linear expansion coefficient of the plate can be reduced, and the performance of an exterior part is improved. The tensile strength of an outer part prepared from the outer part plate provided by the invention is 250-650 MPa, the tensile modulus is 10-25 GPa, and the bending modulus is 8-30 GPa, so that the rigidity and the strength of the outer part are well improved. Meanwhile, the linear expansion coefficient ranges from 7 * 10 <-6 > m/(m.k) to 25 * 10 <-6 > m/(m.k), so that the thermal dimensional stability of the outer part can be effectively controlled, and the fit clearance of the outer part is improved.
本申请公开了一种外观件板材及其制备方法、外观件及其成型工艺、车辆,属于车辆技术领域。本申请提供的外观件板材中的芯层包括纤维和树脂基体,将纤维与树脂基体复合,不仅可以增强外观件板材的刚强度,还可以降低板材的线膨胀系数,从而提高外观件的性能。其中,通过本申请提供的外观件板材制备的外观件的拉伸强度为250~650MPa,拉伸模量为10~25GPa,弯曲模量为8~30GPa,可见,外观件的刚强度得到良好提升。同时,线膨胀系数范围为7×10‑6~25×10‑6m/(m·k),这样可以有效控制外观件的热尺寸稳定性,提高外观件的配合间隙。
