ABSTRACT:
A hole (12) in a panel (10) of composite material is cut by a router or the like to dress it into a rounded hole (12'). A cavity is routed or otherwise formed in the panel (10) to extend across the dressed hole (12') in the direction of maximum tension loads in the panel (10). An insert (16) is secured in the cavity (18). The insert (16) and the cavity (18) have matching plan forms and each has a relatively narrow central portion and enlarged end portions (42, 44). The end portions (42, 44) of the insert interlock with end portions of the cavity (18) such that tension loads will be carried by the insert (16) from a region of the wall (10) on one side of the hole (12') across the hole (12') to a region of the wall (10) on the opposite side of the hole (12').
