Abstract: front page image
(EN)Provided is a composite material structure that enables weight reduction, with consideration given to stress concentrations in areas around holes. A wing (1), which is the composite material structure, is a composite material made of fiber reinforced plastic extending in one direction and in which access holes (5) are formed. A lower outer plate (3) on the wing (1) is subjected to a tensile load in the longitudinal direction. The longitudinal tensile stiffness of peripheral regions (3a) of the access holes (5) is smaller than the longitudinal tensile stiffness of other regions (3b) surrounding the peripheral regions (3a).
(FR)L'invention porte sur une structure en matériau composite qui permet une réduction de poids, prenant en considération les concentrations de contraintes dans les zones autour de trous. Une aile (1), qui est la structure en matériau composite, est un matériau composite fait de matière plastique renforcée par des fibres s'étendant dans une direction et dans lequel des trous d'accès (5) sont formés. Une plaque externe inférieure (3) sur l'aile (1) est soumise à un effort de tension dans la direction longitudinale. La rigidité de tension longitudinale des régions périphériques (3a) des trous d'accès (5) est plus petite que la rigidité de tension longitudinale d'autres régions (3b) entourant les régions périphériques (3a).
(JA) 孔の周縁部の応力集中を考慮した上で、軽量化が可能とされた複合材構造体を提供する。複合材構造体である主翼(1)は、一方向に延在するとともにアクセスホール(5)が形成された繊維強化プラスチック製の複合材とされる。主翼(1)の下面外板(3)には、長手方向に引張り荷重が負荷される。アクセスホール(5)の周縁領域(3a)の長手方向における引張り剛性およびが、周縁領域(3a)を取り囲む他領域(3b)の長手方向における引張り剛性よりも小さい。
