A composite deck assembly includes a baseplate and a top plate secured to the baseplate. The baseplate is formed form a first composite matrix comprising strands of reinforcing fibers oriented in first direction and a polymer resin. The baseplate includes a plurality of ribs and a plurality of laterally extending open channels disposed between the ribs. The top plate is formed from a second composite matrix of reinforcing fibers in a polymer resin, and is secured, optionally releasably, to the baseplate so as to generally enclose at least a portion of the channels. All the reinforcing fibers in the baseplate may be limited to being either the strands oriented in the first direction or matted reinforcing fibers having a random orientation. At least one of the base section and the top plate may be translucent. The open channel configuration simplifies manufacture and lowers cost.

L'invention concerne un ensemble plancher composite comportant une assise et une plaque supérieure fixée à ladite assise. Cette dernière est à base d'une première matrice composite comprenant des brins de fibres de renforcement orientés dans une première direction et d'une résine polymère. L'assise comporte notamment plusieurs nervures et plusieurs canaux ouverts s'étendant latéralement, placés entre lesdites nervures. La plaque supérieure, à base d'une seconde matrice composite de fibres de renforcement en une résine polymère, est fixée, éventuellement libérable, à l'assise de façon à envelopper généralement au moins une partie desdits canaux. Toutes les fibres de renforcement de l'assise peuvent se limiter à des brins orientés dans la première direction, ou être tassées et orientées de manière aléatoire. Au moins soit la section de base, soit la plaque supérieure peut être translucide. La conception de canaux ouverts simplifie la fabrication et en réduit les coûts.
