<p>A process is disclosed for joining an in particular non-textile cellular structure to at least one textile top layer and a textile bottom layer by means of a yarn system, so as to form a sandwich structure. The yarn system is generated by knitting. A honeycombed structure with substantially vertical walls is used as cellular structure. The coating layers designed as multiaxial structures are joined in a single dry operation to the honeycombed structure, forming a flexible, easy to handle mat-like structure that may be transformed in a subsequent step of the process into a hard, highly stiff sandwich material.</p> |
