Metallic inserts are one kind of aerospace fasteners, which are usually installed in metallic components by using an interference fit. However, when metallic inserts are installed in the CFRP laminates by using the traditional installing method, delamination and low efficiencies are troublesome. Therefore, excellent quality and cost-effective installing of metallic inserts into the CFRP laminates remains a challenge. In this paper, a series of experiments were carried out to study the installing-holes distances parameter optimization for metallic inserts bonded into CFRP laminates.
