Abstract
To form a prebonded composite structure, a laminate composite is prepared by positioning a first layer of heat-activated adhesive between a first fabric layer and a second side of a pad and a second fabric layer is positioned adjacent a second side of the pad. The laminate composite is heated to produce a heated laminate composite and the heated laminate composite is positioned between an upper mold and a lower mold. The laminate composite is compressed between the upper and lower molds, thereby compressing the first layer of heat-activated adhesive between the pad and the first fabric layer. In one application, dielectric heat is applied to the laminate composite during the step of compressing the laminate composite.

A method of manufacturing a prebonded composite structure, the method comprising the steps of:
- preparing a laminate composite, the step of preparing a laminate composite comprising the sub-steps of:
- (i) positioning a first layer of heat-activated adhesive between a first fabric layer and a first side of a pad;
- and
- (ii) positioning a second fabric layer adjacent a second side of the pad;
- heating the laminate composite to produce a heated laminate composite;
- bonding the pad to the first fabric layer;
- and
- bonding the pad to the second fabric layer by permitting flow of the first layer of heat-activated adhesive through the pad.
