The replacement of the conventional mechanical joint using bolts, etc., with an adhesive joint, among methods for assembling parts, has been studied in terms of weight and cost reduction. One of the issues in replacement is the curing time of the adhesive. To address this issue, the principle of the rapid heating method using near-infrared radiation developed by Kubota Research Associates, Inc. was verified. In addition, a simulation tool which allows the estimation of the change of temperature of the adhesive layer by near-infrared heating was developed to facilitate the study of the applicability of the method.
