Light-weight sandwich composites can be tailored to satisfy many specific application requirements and are inevitable for modern structures where reduced weight is extremely critical. However, these structures are highly vulnerable to debonding at the skin-core interface. The skin-core adhesion is an extremely crucial part of a sandwich structure; mostly responsible for transferring load and maintaining integrity between the components. Keeping this into consideration, the effectiveness of a straightforward but productive technique of using an additional adhesive layer between the face-sheet and core for improving the damage resistance of sandwich structures is investigated. Contribution of a reinforced skin-core interface via adhesive bonding on the impact and post-impact performances, i.e., the maximum load and energy dissipation capacities and failure modes of the sandwich composites were experimentally investigated. Application of additional adhesive at the skin-core interface while manufacturing CFRP/end-grain balsawood sandwich composite demonstrated improved structural performance with no significant variation in density nor requiring additional complex manufacturing procedures. Experimental methods such as low-energy impact, compression-after-impact (CAI), and core compression tests were utilized to illustrate the influence of the interface enforcement. Experimental results indicate that interface adhesive application reinforces the structure's impact tolerance and improves post-impact response. Controlled skin-core debonding primarily attributes to the improved features.
