Provided is a preform member bonding method, in a RTM process, for bonding a preform member and another member (a preform member or a hardened member) together with an adhesive. The preform member bonding method includes: beforehand obtaining data on a range of a level of progress in hardening of the adhesive which allows the adhesive to penetrate the preform member, and data on a range of the level of progress in the hardening of the adhesive which decreases bonding strength of the adhesive; and controlling the level of progress in the hardening of the adhesive by heat-treating the adhesive based on these data, before the preform member comes into contact with the adhesive.

The preform member bonding method according to claim 1, wherein the level of progress in the hardening of the adhesive is examined by carrying out an evaluation test on how much the adhesive is sucked into the preform member at a time when the preform member comes into contact with the adhesive, and a peeling test on the adhesive at a time when resin and the adhesive are completely hardened in the RTM process.
