Composite material and element with electrical continuity insured through it, its manufacturing process and use on aircraft

摘要

The composite material includes conductive lining formed by sheets of a material that has an organic matrix with a critical hardening temperature. The matrix is reinforced with mineral or organic fibres. The sheets (7) are joined by overlapping their edges. A region at the sheet edge (8) carries a layer of a metal conducting material (6), which is brought into contact with the similar layer at the edge of the joining sheet. The conducting material has a fusion temperature significantly higher than the critical temperature of the organic matrix. A second metal region (1) at the edge of the sheets has a fusion temperature significantly lower than the other metal layer, so the sheets are joined by welding the lower fusion temperature metal.
