Abstract
It is disclosed a composite material and a process for producing such a composite reinforced material, comprising the steps of arranging a plurality of layers of reinforcing fibres, impregnating said layers with a resin-based matrix, laminating said layers of reinforcing fibres by addition of pressure and/or heat, placing between said layers of reinforcing fibres an intermediate layer of polymer nanofibers, wherein said intermediate layer of polymer nanofibers is interleaved between said layers of reinforcing fibres by laying a membrane of polymer nanofibers adhering to a backing substrate before said lamination step, said membrane of polymer nanofibers being obtained by direct electrospinning on a backing substrate by a needleless technique, and wherein it is provided an anti-sinking feature before said lamination step, which prevents a early sinking of said membrane of polymer nanofibers into said resin-based matrix.
