Crushable washers proposed for use in protecting composite-material (matrix/fiber) panels against overloads applied by nut-and-bolt fasteners. Intended for use at drilled holes, where strengths of composite panels reduced by exposure of ends of fibers. Washer consists of metal skin filled with microcapsules of epoxy resin and hardener. Alternatively, filled with fibers collapsing under given load. Crushing action simultaneously fractures microcapsules (if used), releasing components of epoxy. These components mix and fill bolthole and fiber-reinforcement interstices. Epoxy then hardens, locking fasteners in place.
