Abstract
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.
