Abstract

A method of fabricating a fiber matrix composite structure including assembling a plurality of plies of fiber-reinforced polymer-matrix material on a mandrel; engaging an ultrasonic horn with the top surface of uppermost ply; and orienting the horn at an acute angle with respect to the top surface and energizing the horn to inducing a shear force in the plies to heat and consolidate the plies.
