Experimental Study for the Impact Characteristics of Expanded EPP/EPS Foams

Abstract

In the present study, quasi-static tests and impact tests were performed for investigating the mechanical behaviour of EPP (Expanded polypropylene) and EPS (Expanded polystyrene). Four different density cylindrical type specimens were prepared for EPP and EPS and 0.001 s-1 and 0.1 s-1 of strain rate conditions for quasi-static tests and 100 J, 200 J and 300 J of incident energy conditions for the instrumented impact tests were considered. 초 록: 본 연구에서는 발포 폴리프로필렌(Expanded polypropylene)과 발포 폴리스티렌(Expanded polystyrene)의 준 정적 시험(Quasi-static test) 및 계장화 충격 시험(Instrumented impact test)을 수행하였다.
