This study focuses on the detailed characterization of modified polyurethane foams, emphasizing their quasi-static compression behaviour and microstructural properties, to evaluate their potential application in shock-absorbing systems. Through systematic synthesis, we produced various formulations of polyurethane foams. We subjected them to comprehensive quasi-static compression tests to understand their deformation and energy absorption characteristics under controlled loading conditions. Concurrently, microstructural analyses were conducted to elucidate the relationship between the cellular architecture of the foams and their mechanical responses. Although the foams were not directly integrated into shock absorbers, the findings lay a foundational understanding of how their structural and compositional variations influence performance metrics crucial for shock absorption applications. This research contributes to the broader knowledge base required for the future design and optimization of polyurethane foam-based shock absorbers, highlighting critical areas for further investigation and development.
