EVALUATION OF THE IMPREGNATION CHARACTERISTICS OF CARBON FIBER-REINFORCED COMPOSITES USING POLYPROPYLENE GEL-FILM.

Soo Jin Ham (Chonbuk National University) Seung A Song (Chonbuk National University) Seong Su Kim (Chonbuk National University)

 

In this study, we fabricated CFRPP by using a high speed resin transfer molding (RTM) with PP gel-film whose flow direction is through-thickness for the preform to solve the low impregnating property of the CFRPP.

FLOW BEHAVIOR OF COMPLEX SHAPED HYBRID CFRTP DURING COMPRESSION MOLDING

Daiki Kobayashi (University of Tokyo) Yi Wan (University of Tokyo) Hanchul Lee (University of Tokyo) Taro Nakamura (University of Tokyo) Haowen Wei (University of Tokyo) Jun Takahashi (University of Tokyo) Isamu Ohsawa (University of Tokyo)

 

The flowability of hybrid CFRTP was investigated by using rib formation mold. The fiber distribution of the plate part under the charging port of ribs was relatively kept successfully and the flexural rigidity was improved by hybridization.
