Fiber reinforced plastic, FRP, is superior to metals in terms of specific strength, and formability. FRP is, however, more expensive than major metals. Glass fiber is relatively inexpensive compared to carbon and aramid fibers, so that GFRP is used for usual vessels. Unfortunately, the stiffness of GFRP is not high enough for large vessels. For these reasons, metals are still important materials especially for large structures. Large vessels are usually hybrid structures of GFRP and metals. In this paper, non-chemical reinforcing method for GFRP/metal co-cured joint is introduced. Projection is made on metal adherend mechanically by inserting metal hook-shaped pin. Joining strength increased using mechanical interlocking. The joining strength is evaluated by tensile test of single-lap joint specimen. As a result, tensile shear strength of joint with projection increased, and the life of joint became longer because mechanical interlocking of adherends remained after adhesive failure.
