Paragraph starter

The selection of cushioning materials for this design project was informed by research into advanced composites. For instance, a study by Tan et al. (2020) demonstrated that silicone rubber foam/SiO2 nanocomposites exhibit significantly superior fatigue buffering performance compared to expanded polyethylene, maintaining 99.0% height retention after 6.0 million compression cycles, a stark contrast to EPE's 54.5% retention after 0.29 million cycles. This indicates the potential for enhanced product protection and reduced material degradation over the product's lifecycle.
