The optimum composite joint design is the one capable of distributing stresses over a wide area rather than to concentrate them at a point. Adhesively bonded joints can satisfy these requirements, however, most of the adhesives are brittle, and brittle failure is unavoidable. This was the motivation of developing what is called the SNAP joint. The snap joint technology developed by W. Brandt Goldworthy & Associates, Inc. The concept is based on similar joining technology used for connecting wooden parts (wood is considered as natural orthotropic composites). Also, this technique is very similar to techniques which were used a decade or so again for plastic.
