Study to Improve Reliability Control Technology of Adhesive Bonding in Composite Structures: Systematic Evaluation of Bonding Process Factors to Determine Their Degrees of Influence
Adhesively bonded composite structures can transfer loads efficiently and are expected to contribute to reducing assembly costs. However, the current status of reliability given to this joining method by the certification authorities such as the Civil Aviation Bureau is low. In this report, the process factors that can affect the adhesive strength were extracted, and their degrees of influence were evaluated quantitatively. The results can be used as the foundations for devising an appropriate bonding process, which is considered to help greatly improve the reliability of adhesive bonding.
