Claims24
A composite material comprising:
- a first conductive fibrous layer comprising a plurality of electrically conductive fibers;
- a second conductive fibrous layer comprising a plurality of electrically conductive fibers;
- a resin layer located between said first conductive fibrous layer and said second conductive fibrous layer and defining an average thickness therebetween, said resin layer comprising a polymeric resin and a plurality of electrically conductive particles;
- wherein at least 50% of said conductive particles have a diameter that is within 10 μm of the average thickness of said resin layer.

A composite material comprising:
- a first conductive fibrous layer comprising a plurality of electrically conductive fibers;
- a second conductive fibrous layer comprising a plurality of electrically conductive fibers;
- a resin layer located between said first conductive fibrous layer and said second conductive fibrous layer and defining an average thickness therebetween, said resin layer comprising a polymeric resin and a plurality of electrically conductive particles defining an average diameter;
- wherein said electrically conductive particles have an average diameter between 0.3 μm and 100 μm, and wherein said resin layer has a average thickness between 10.3 μm and 110 μm.
1 more element
A prepreg comprising:
- a conductive fibrous layer comprising a plurality of electrically conductive fibers;
- a resin layer located on at least one side of side conductive fibrous layer, said resin layer comprising a polymeric resin and a plurality of electrically conductive particles;
- wherein said resin layer is configured to join with a corresponding resin layer of an adjoining prepreg and thereby define an interleaf resin layer thickness;
- and
- wherein at least 50% of said conductive particles in said resin layer have a diameter that is within 10 μm of the interleaf resin layer thickness.
