CA 2416570

A composite comprising a structural component and a matrix component, the structural component comprising structural fibres and a toughening additive comprising non structural fibres of a first thermoplastic material and the matrix component comprising a second thermoplastic material. The structural component is a fabric formed from the structural fibres and the non structural thermoplastic fibres, the fabric comprising non structural thermoplastic fibres which are in fibre form in the final composite. The first and second thermoplastic materials differ as to their molecular weight or are dissimilar.

L'invention se rapporte à un composite comportant un composant structurel et un composant matriciel, ledit composant structurel comprenant des fibres structurelles et un additif de renforcement comprenant des fibres non structurelles d'une première matière thermoplastique, et le composant matriciel comprenant une seconde matière thermoplastique. Le composant structurel est un tissu formé à partir des fibres structurelles et des fibres thermoplastiques non structurelles, ledit tissu comportant des fibres thermoplastiques non structurelles qui se présentent sous la forme de fibre dans le composite final. Les première et seconde matières thermoplastiques possèdent un poids moléculaire différent ou peuvent être de nature différente.
