FIBROUS STRUCTURE COMPRISING A LOADED BINDING AGENT

摘要

The invention relates to a flat reinforcing fibrous structure which is permeable to thermosetting resins, said structure comprising fibres and a particle load which are interconnected by a binding agent, the binding agent, fibres and particles being homogeneously distributed over the thickness of the structure. The inventive structure comprises between 80 and 98.7 wt. % of fibres, between 1 and 20 wt. % of binding agent, and between 0.3 and 10 wt. % of particle load. The structure can be impregnated by a resin for producing a composite material. The presence of the particles in the binding agent improves the degassing speed and facilitates the impregnation.
