Substantially rigid panel of recyclable composite material and its process of production

摘要

The rigid panel (1), without a frame, comprises two reduced thickness walls (2,3) in a recyclable composite material. These walls are fixed to each other and between them are spaces (5). The composite material comprises a thermoplastic matrix of synthetic fibres reinforced with cellulose fibres. The two walls are made of the same material with the same or different Young's Modulus. The two walls have ribs (4) between them and are fixed directly to each other at the tops of these ribs. The structure can consist of a plane upper wall and a lower ribbed wall. The upper wall being intended to support loads.
