This paper presents an experimental study of fusion bonded polypropylene (PP)-glass composite joints in the context of small craft manufacture. The objective is to investigate the manufacture of lap and T-joints as a structural part of a small boat and study their properties, because a joining technique is a fundamental requirement of any boat construction technology. Results show that woven precursor materials are preferred for joint manufacturing, and that PP interlayers improve bond quality for both lap and T-joints. It was also found that this technique produces higher lap shear strength values than adhesives and resistance welding, and that pull-out strength values were comparable to those of thermosetting designs, demonstrating that fusion bonding is a suitable joining technique for thermoplastic composite craft. ©2010: The Royal Institution of Naval Architects.
