A rigid composite material comprising an organic fire retardant fibrous element, an intumescent material and a structure conferring amount of a cross- linkable resin is provided. When the composite material is exposed to conditions under which charring of the fire retardant fibrous element, intumescent and resin occurs, the charred surfaces of the fire retardant fibrous element, intumescent and resin to bond together. Methods of preparing the composite material are also provided. The materials can be used in load bearing applications and are able to act as fire barriers under conditions of heat and flame.
L'invention concerne un matériau composite rigide comprenant un élément fibreux retardant les flammes, une matière intumescente et une quantité de résine réticulable suffisante pour créer une structure. Lorsque le matériau composite est exposé aux conditions provoquant la carbonisation de l'élément fibreux retardant les flammes, de la matière intumescente et de la résine réticulable, les surfaces carbonisées de l'élément fibreux retardant les flammes, de la matière intumescente et de la résine réticulable se collent les unes aux autres. L'invention concerne aussi des procédés pour préparer le matériau composite. Ces matériaux peuvent s'utiliser dans des applications sous charge et, confrontés aux flammes et à la chaleur, peuvent agir comme une barrière contre les flammes.
