The structure of layer for incorporation in a composite structure reinforced with continuous fiber, composite structure, and methods for preparing a layer of reinforcement for use in a composite structure, and a composite material.
The structure of layer for incorporation in a composite structure reinforced with continuous fiber, composite structure, and methods for preparing a layer of reinforcement for use in a composite structure, and a composite material.
A secondary ply structure suitable for incorporation into a continuous fiber reinforced composite structure comprising a matrix material and a plurality of fiber ply reinforcing structures, a continuous fiber reinforced composite material so formed, and a method for the fabrication of the same are described. The secondary ply comprises a carrier sheet for example in the form of a ply of primary fibers and carries a two dimensional planar array of secondary fibers extending outwardly of the plane of the sheet into a third dimension in generally aligned manner and disposed across at least a major part of the surface thereof in generally aligned manner to provide out of plane reinforcement in the consolidated structure.
