Title:
落雷防護相互接続を有する多層複合材構造体及び外板留め具から雷電流をそらす方法
Document Type and Number:
Japanese Patent JP6941422
Kind Code:
B2
Abstract:
A multilayer composite structure (52) with integrated fastener- to-conductive layer surface lightning protection interconnection employs a conductive layer (72) with an inner surface (61) and a plurality of chamfered recesses (68) forming countersinks (74) in an outer surface (59). A carbon-fiber reinforced plastic (CFRP) composite layer is disposed on the inner surface (61) of the conductive layer (72) and conforms to the surface shape. A plurality of holes (70) extend through the plurality of chamfered recesses (68) in the conductive layer (72) and the adjoining CFRP composite layer in a manner such that the conductive layer (72) defines a countersink portion extending into the openings of the plurality of holes (70). The chamfered recesses (68) in the conductive layer (72) provides an electrically conductive surface area that contacts conductive countersunk fasteners installed within the plurality of holes (70) to enable current sharing between groups of neighboring fasteners (78).
