Effect of gravity on resin flow behavior by VARI process

摘要

The resin flow behavior in vacuum assisted resin infusion molding process (VARI) of foam sandwich materials was studied through visualization flow experiments. The experimental results show:Gravity of resin makes the mold filling time increase when θ changes from 0° to 90°, and mold filling time lengthens with the increase of θ; gravity shortens the filling time when θ changes from 0°to-90°, and mold filling time decreases with the increase of the absolute value of θ.
