Abstract

Abstract: The VARI process simulation of panel with hat-shaped stringer is carried out by PAM-RTM software. During the simulation, effect of the distribution position and quantity of injection ports and vent ports in typical areas such as panel skins and stringers, gravity of resin and vent port close sequence were analyzed respectively. The simulation results show that the possibility of defect appearance tends to be the lowest, when flow channel is designed in following way: ① The injection ports are distributed at panel skin edge and the vent ports at top of stringer. ② The vent ports close sequentially from the edge of the panel to the central area. Through the simulation results which were verified by the panel manufacturing with VARI and quality inspection results, the optimal resin flow and tooling design was finally obtained.

Key words: simulation, composite panel with hat-shaped stringer, VARI process, injection, vent
