자전거 프레임 및 산업 부품과 같은 다양한 산업 분야에 PETG 열가소성 복합 재료를 적용하려면 제조 된 복합 재료의 내충격성, 내구성, 기계적 특성 및 3D 분석을 안정성 검증이 필수적이다. 본 연구에서는 비정질 수지 인 PETG 수지의 기계적 특성, 내구성 및 내충격성을 향상시키기 위해 다양한 질량분율의 POE(폴리올레핀 엘라스토머)를 보강하여 화합물 및 사출 성형 공정을 수행 하였다. POE질량분율에 따른 PETG 열가소성 복합재의 열적 및 기계적 특성 및 샤르피 충격 강도 등에 대한 분석을 수행 하였다. 열적 및 기계적 특성 분석 결과, POE 소재가 첨가 된 PETG 열가소성 복합재의 경우 열적 및 기계적 특성이 감소하는 경향이 있지만 내충격성이 우수한 경향을 나타내었고, POE첨가에 따른 3D 전산해석 결과, 파손여부 없이 우수한 안정성을 나타내었다.
Abstract
In order to apply thermoplastic composites using PETG resin to various industrial fields such as bicycle frames and industrial parts, it is necessary to verify the impact resistance, durability, mechanical properties and 3D analysis of the manufactured composite materials. To improve the mechanical properties, durability and impact resistance of PETG resin, an amorphous resin, in this study, compound and injection molding process were carried out enhanced various weight percent POE(polyolefin elastomer). The thermal and mechanical properties of the thermoplastic composites, and the charpy impact strength, The analysis was performed to evaluate the characteristics according to weight percent of POE. Charpy impact strength test was conducted to analyze the impact characteristics, and the fracture section was analyzed after the impact strength test. In the case of POE material-added thermoplastic composites, thermal and mechanical properties tend to decrease, but workability and impact resistance tend to be superior to those of PETG materials.
