The invention relates to an underbody component (100) for a motor vehicle, such as an underbody protection device, in particular for a fuel tank or a power battery, which underbody component is designed as a flat plastic component and is composed of a plurality of fixedly connected plastic layers (10, 20, 30). According to the invention, the outer cover layer (20) of the base part (100) is formed from a multi-ply laminate, at least one inner ply (22, 23, 24) of the laminate being designed at least partially in a different color (F2) with respect to the outer ply (21) of the laminate such that a visible color contrast occurs at a damage point (B) in the event of a damage to the base part (100). The invention also relates to an alternative embodiment in which the core layer (30) is designed in a different color with respect to the at least one cover layer (10, 20).

    本发明涉及一种用于机动车的底部构件(100),如尤其是用于燃料箱或动力电池的底部保护装置,该底部构件被构造为面状的塑料构件并且由多个固定连接的塑料层(10、20、30)构成。底部部件(100)的外部的覆盖层(20)由多板层的层压板形成,其中,该层压板的至少一个内板层(22、23、24)相对于层压板的外板层(21)至少在局部被设计成不同的颜色(F2),使得在底部构件(100)损坏的情况下在损坏部位(B)处产生可见的颜色对比。本发明还涉及一种另选的实施方式,其中,芯层(30)相对于至少一个覆盖层(10、20)被设计成不同颜色。
