軟質エポキシフォームを用いた柔軟性プロテクターの開発

抄録

Foamed resin materials have been widely used as cushioning materials for protective equipment for sports and daily life. In order to apply to the protective equipment, flexible epoxy foams having extremely high strain rate dependency of compressive properties was fabricated by reducing the crosslink density of the resin. Compression tests in wide range of strain rate were performed to evaluate strain rate effects on compressive property of the foams. The experimental results revealed that the fabricated soft epoxy foams have excellent flexibility in low strain rate and high compressive stress in high strain rate, independent of the foam density. Furthermore, the application of the epoxy foam to protectors was examined.
