Abstract

In this study, epoxy-modified acrylate was synthesized. The synthesized acrylate was added to the composition for sheet molding compound (SMC) in the range of 5 phr to 15 phr. The prepared SMC prepreg was molded at high temperature and pressure to produce a glass fiber reinforced composite. Physical properties such as tensile and impact strength of the composite were measured, respectively. Experimental data show that the composite with 5 phr of synthesized acrylate has 20% improved tensile strength and 12% improved impact strength than that of the reference sample.

본 연구에서는 에폭시 수지를 개질 한 변성 아크릴레이트를 합성하였으며, 이를 기존의 유리 섬유 복합소재에 사용하는 SMC 조성물에 5 phr - 15 phr을 첨가하여 SMC 소재를 제조하였다. SMC 프리프레그를 고온고압 (150 ℃, 10 bar)에서 컴프레션 몰딩방법으로 성형하여 유리섬유 복합소재를 제조하였으며, 제조된 복합소재를 가공하여 인장강도, 충격강도 등의 기계적 물성을 연구하였다. 실험 결과 합성된 변성 아크릴레이트를 5 phr을 포함하는 복합소재가 합성 아크릴레이트를 포함하지 않는 binder 샘플보다 인장강도는 약 20%, 충격강도는 약 12% 향상함을 보였으며, 이는 합성 아크릴레이트가 폴리에스터와 반응할 수 있는 4개의 아크릴 기를 가짐으로써 가교반응을 강하게 하면서 기계적 강도가 향상됨을 확인하였다.
