PURPOSE:To manufacture a resin composite pipe and a resin composite pipe joint for which a bonding agent to be able to retain large bonding strength under the severe conditions can be used and on which the release of bonded faces is not generated. CONSTITUTION:A thermoplastic resin pipe 2A of a thermoplastic resin pipe joint is used as a core material and a fiber reinforced thermosetting resin layer 4 is formed on the outer peripheral face of said core material through a bonding agent layer 3, and polyol as a base and isocyanate as a crosslinking agent are blended for the bonding agent layer 3. Unsaturated polyester resin is also added therein, and the blending ratio of polyol, isocyanate and unsaturated polyester resin is 1-10 pts.wt. of isocyanate and 2-10 pts.wt. of unsaturated polyester resin to 10 pts.wt. of polyol. |
