A Study on the Pultrusion Process of Thermosetting Composites Considering Thermally induced Deformation

열변형을 고려한 열경화성수지 복합재료의 펄트루젼 공정에 관한연구

A synthesized model of pultrusion process considering thermally induced deformatiion was established. The model was composed of liquid resin flow model thermo-chemical analysis and linear elastic analysis. in order to verify the above-mentioned models several experiments were performed. A laboratory scale pultrusion line was established and glass/polyester composites were fabricated. the experimental results were compared with the calculated ones. The model successfully could estimate degree of cure pulling force and amount of process-induced deformation.
