<P>PROBLEM TO BE SOLVED: To provide a composite material structure that reinforces areas around holes against stress concentrations and also enables weight reduction. <P>SOLUTION: A wing 1 has a box structure. A lower outer plate 3 on the wing 1 is provided with: a center section 3b, made of metal, which extends in one direction and in which access holes 5 are formed; and a front section 3a and a rear section 3c, both made of fiber reinforced plastic, which extend in the one direction and are connected to both sides of the center section 3b respectively. The metal used for the center section 3b is preferably a titanium alloy or an aluminum alloy. <P>COPYRIGHT: (C)2012,JPO&INPIT |
