초록

프리폼 성형은 섬유 직조물을 이용한 RTM 성형에 있어서 매우 중요한 부분을 차지하고 있다. 탄소 섬유 직조물의 프리폼의 변형은 소재의 강도에 영향을 미치며, 그 중 전단 잠김 각도를 넘어서는 힘이 작용하게 되면 제품에 주름이 발생되어 RTM공정 시 불량발생의 원인이 된다. 그러므로 본 연구에서는 탄소섬유직조물의 전단변형 허용치를 정량화하고 실제 직조물의 성형과 수치모사를 이용하여 성형 특성을 검증하고자 한다. 그 결과 섬유 방향의 설정에 따른 주름의 특성을 확인하고 그 결과를 평가하였다. 앞에 언급한 물성 측정 결과들을 이용하여 수치해석을 수행하였고, 이 결과를 실험 결과와 비교 분석하였다.

Preforming is crucial in resin transfer molding process using woven fabric. When shear deformation exceeds the locking angle, wrinkles are generated in the preform, which causes defects in the RTM process. Therefore, in this study, the allowable shear deformation limit of carbon fiber woven fabrics is quantified and the molding characteristics are verified using the actual fabric forming. As a result, the characteristics of creases according to the layer setups have been examined and the results have been discussed. Numerical analyses have been also performed using measured shear properties. These results have been compared with the experimental results.
