Claims

3. THE METHOD FOR ADHESIVELY JOINING TOGETHER CONTIGUOUS THERMOSETTING RESIN IMPREGNATED FILAMENT REINFORCED MEMBERS COMPRISING:

(A) APPLYING TO AT LEAST ONE SURFACE OF ONE OF THE MEMBERS A HEAT CURABLE ADHESIVE;

(B) PLACING THE ADHESIVE COATED SURFAE OF ONE SAID MEMBER IN MATING SURFACE RELATION WITH ANOTHER SAID MEMBER;

(C) PLACING UPON THE SURFACE OF ONE SAID MEMBER AT A LOCATION OVERLYING SAID ADHESIVE A LENGTH OF COMBUSTIBLE FUEL ELEMENT WHICH GENERALLY CONFORMS TO THE CONTOUR OF SAID SURFACE;

(D) TEMPORARILY SECURING IN SUCH POSITION SAID FUEL ELEMENT;

AND (E) IGNITING SAID FUEL ELEMENT WHEREBY THE SAME BURNS PROGRESSIVELY AND GENERATES HEAT THAT IS TRANSMITTED TO SAID ADHESIVE TO ACCELERATE ITS CURING.
