METHOD OF MAKING REINFORCED STRUCTURAL COMPOSITE ASSEMBLIES AND ASSEMBLY PRODUCED THEREBY ABSTRACT OF THE DISCLOSURE The present invention contemplates a method of making a hollow section fiber reinforced composite assembly useful as a structural component wherein a first rigid, fiber reinforced, EB (electron beam) curable-thermoplastic composite member is formed by liquid castable molding (LCM) thermoplastic-forming material about a fiber reinforcement and a second rigid, fiber reinforced, EB curable thermoplastic composite member is similarly formed. An EB-curable adhesive material is provided at an interface between the assembled composite members. The composite members are then partially fusion bonded (e.g. ultrasonic tack welded) together at regions of the interface devoid of adhesive to form a hollow section for subsequent curing. The hollow section is subjected to irradiation by high energy electrons effective to cure the adhesive material and the partially bonded first and second fiber rein- forced, EB curable-thermoplastic members to a thermoset condition useful in structural applications.
