Method of filling voids around countersunk fastener heads

A method for a structure 120 having a countersunk fastener head 112 includes forcing an aliphatic urethane surfacer 430 into a void 124 around the fastener head. The method is applicable to an aircraft 200 comprising a composite skin 420 and a plurality of fasteners 410 having heads 412 countersunk...

Zusammenfassung:	A method for a structure 120 having a countersunk fastener head 112 includes forcing an aliphatic urethane surfacer 430 into a void 124 around the fastener head. The method is applicable to an aircraft 200 comprising a composite skin 420 and a plurality of fasteners 410 having heads 412 countersunk in an exterior surface of the skin 420.
