ABSTRACT:
A process for the preparation of fiber-reinforced flat bodies containing a hardenable binder is described, wherein a core layer containing the prepared, unhardened (liquid) binder is placed between a cover layer and a backing layer; in order to provide this three layer body with its own internal cohesion even in the unhardened condition and to improve the mechanical properties of the body in the hardened state, the three layers, at least one of the outer ones of which consists of fibers capable of active fiber bonding, are needle bonded together prior to the hardening of the binder, so that the layers will hold together in the deformable state, whereupon the binder is hardened, while the fibers provide the body with an elasticity different from that of the hardened core layer. Prior to hardening, the composite body may be provided with orifices or slits, without the loss of the mass of the core layer from the body. The mass of the core layer is held by holding fibers, introduced during the needle bonding process and connecting the cover layer with the backing layer through the core layer.
