This document outlines a study on the design and analysis of self-healing sandwich composites. It discusses different approaches to self-healing including capsule-based, vascular-based, and intrinsic methods. E-glass fiber and PVC foam were selected as the facing and core materials, with epoxy resin and a self-healing polyurethane resin used to bond the layers. Specimens were fabricated and tested for flexural rigidity, impact resistance, and water absorption. Results showed the self-healing composites had better impact resistance but lower flexural rigidity compared to epoxy composites, and exhibited less water absorption. The study aims to analyze these materials for applications in aircraft panels and
