PROBLEM TO BE SOLVED: To provide a fastener system and a method, which improve electrical contact and conductivity with a composite structure such as a carbon fiber reinforced plastic (CFRP) structure.SOLUTION: A fastener 10 includes an elongated shaft 14 that has a first end 16 with a head portion, a second end 18 with a threaded portion 42, and a shaft body 20 therebetween. At least one feed channel extends from an opening 40 at the threaded portion 42 to pass through the shaft body and terminate proximal to the head portion 22. The shaft body radially expands upon pressure injection of a resin filler into the feed channel, when the fastener is installed in a corresponding fastener hole formed in a composite structure. Upon radially expanding, the outer surface of the shaft body contacts with an inner hole surface of the corresponding fastener hole, resulting in the fastener providing electrical contact with the composite structure and providing distribution of electric current.SELECTED DRAWING: Figure 1B

    【課題】炭素繊維強化型プラスチック(CFRP)構造物といった複合構造物との電気的接触及び伝導性を改善するファスナシステム、及び方法に関する。【解決手段】ファスナ10は、ヘッド部を有する第1端部16、ねじ部を有する第2端部18、及び、それらの端部の間のシャフト本体20を有する、細長いシャフト14を含む。少なくとも1つの供給チャネルが、ねじ部42にある開口40からシャフト本体を通って、ヘッド部22の近位で終端するように延在する。シャフト本体は、ファスナが複合構造物内に形成された対応するファスナ孔の中に取り付けられている場合、樹脂充填物が供給チャネル内に加圧注入される際に、径方向に拡張する。径方向に拡張する際に、シャフト本体の外表面は、対応するファスナ孔の内側孔表面に接触し、その結果、ファスナが、複合構造物との電気的接触を提供し、かつ、電流の分配を提供することになる。【選択図】図1B
