Plastic composite component formed of at least two layers (12, 14, 16), wherein a first layer consisting at least in part of a heat-curing synthetic resin and a second layer consisting at least in part of an elastomer are joined by an application of energy, such as a joint heat treatment or a radiation with UV light, in a single processing step, and wherein the elastomer layer contains at least 0.5 pph (parts per hundred/parts of the cross-linking agent per hundred parts of rubber) of at least one cross-linking agent from the group of peroxides, amines and/or bisphenols, wherein the plastic composite component is formed of a thin hard plastics outer layer, at least one elastomer layer adjoining the former on the inside, and at least one metal and/or plastics carrier layer adjoining said elastomer layer on the inside and made of a fiber-reinforced plastic, a carbon fiber reinforced plastic or a glass fiber reinforced plastic, and is arranged as an impact protection part • on the front edge of a wing, an airfoil or a tail unit of an aircraft, or • on the front edge (in the direction of rotation) of a rotor blade of a helicopter or a wind wheel, or • on a bodywork component of a vehicle, such as a bumper or a bonnet, or • on a component of a vehicle subjected to swirling objects, such as an underbody protection part of a road vehicle or rail vehicle, a chassis strut, a steering gear, a driveshaft or cardan shaft, a pedal bearing of a mountain bike provided in particular with a carbon frame, or • on an inner cladding of a land-, water-, air- or spacecraft, or • on the inner face of a cavity of land-, water-, air- or spacecrafts, which cavity is accessible for maintenance purposes, for protection against damage caused by falling tools, or • on the surfaces facing the cargo of open or closed transport spaces, such as cargo holds of transporters and lorries or containers, or • on the front hull region or the bilge region of a watercraft, such as a sports boat, a speedboat or a kayak, or • on highly loaded effective areas of sports equipment, such as the blade area of ice hockey sticks, the base contact faces of Nordic walking sticks or ski sticks or the paddle blades of canoe or kayak paddles or at least partly forms the latter, characterized in that the plastics outer layer is formed of polyethylene, in particular ultra high molecular weight polyethylene (UHMW-PE), high molecular weight polyethylene (HMW-PE) or polytetrafluoroethylene (PTFE). • on the front edge of a wing, an airfoil or a tail unit of an aircraft, or • on the front edge (in the direction of rotation) of a rotor blade of a helicopter or a wind wheel, or • on a bodywork component of a vehicle, such as a bumper or a bonnet, or • on a component of a vehicle subjected to swirling objects, such as an underbody protection part of a road vehicle or rail vehicle, a chassis strut, a steering gear, a driveshaft or cardan shaft, a pedal bearing of a mountain bike provided in particular with a carbon frame, or • on an inner cladding of a land-, water-, air- or spacecraft, or • on the inner face of a cavity of land-, water-, air- or spacecrafts, which cavity is accessible for maintenance purposes, for protection against damage caused by falling tools, or • on the surfaces facing the cargo of open or closed transport spaces, such as cargo holds of transporters and lorries or containers, or • on the front hull region or the bilge region of a watercraft, such as a sports boat, a speedboat or a kayak, or • on highly loaded effective areas of sports equipment, such as the blade area of ice hockey sticks, the base contact faces of Nordic walking sticks or ski sticks or the paddle blades of canoe or kayak paddles
