PURPOSE:To obtain a composite body having good connecting strength and airtightness by disposing an organic alkoxisilane compound condensation product on the connecting part having a thermoplastic resin tubular body and a metallic tubular body being shrink-fitted thereto. CONSTITUTION:In the case of resinification of metallic components for automobiles and home electric appliances, in the connecting techniques of a resin pipe and a metallic pipe, the thermoplastic resin tubular body 1 as a resin pipe is heated through heating within an oven in order to expand the inner wall of the resin tubular body 1 in its diameter. In the next place, a metallic tubular body 1 as a metallic pipe is inserted in the resin tubular body 1, which is applied with an organic alkoxisilane compound on the connecting surface and has an outer diameter approximately equal to the inner diameter of the resin tubular body 1 at an ordinary temperature. In this manner, the alkoxisilane compound is heated by the resin tubular body 1 so as to bring about hydrolysis and condensation reaction, with the result that an organic alkoxisilane compound condensation body 3 having a three-dimensional crosslinked structure is produced therebetween so that both of them 1, 2 are firmly connected. |
