Abstract

This study developed the in-situ stamp-forming process using the multi-axis robotic arm to fabricate thermal composite parts. Optimal fabrication parameters with the multi-axis robotic arm were determined using finite element analysis and these parameters were further refined through the practical manufacturing process. A comparison between the manufactured parts and finite element analysis results was conducted regarding thickness uniformity and wrinkle distribution to confirm the validity of the finite element analysis. Additionally, to evaluate the formability of the manufactured composite parts, measurements of crystallinity and porosity were taken. Consequently, this study establishes the feasibility of the In-situ stamp-forming consolidation using a robotic arm and verifies the potential for producing composite parts through this process


본 연구에서는 다관절 로봇 암을 활용한 열 성형 공정을 통해 열가소성 복합재 부품을 개발하였다. 유한요소해석을 기반으로 로봇 암이 적용된 고속 열 성형 공정의 최적 공정 변수를 도출하였고, 이를 기반으로 실제 제작 공정을 통해 공정 변수를 구체화하였다. 제작된 부품과 유한요소해석 간의 두께 균일성, 주름 분포를 비교하였고, 이를 통해 유한요소해석의 타당성을 입증하였다. 또한, 제작된 복합재 부품의 성형성을 평가하기 위해 결정화도와 기공률을 측정하였고, 그 결과 우수한 성형성을 보인 것으로 평가하였다. 이에 따라 본 연구는 로봇 암 기반의 고속 열 성형 공정을 통한 공정 확립과 이를 통한 복합재 구조의 제작 가능성을 확인하였다
