Unidirectional Infusion Problems

Hi All,

I am having trouble wetting out UD carbon in an infusion job.

Temp: 22C
pressure diff; 981mBar
resin; VE671
layer 1,3,5 200 CF twill
layer 1 & 4 UD 200 carbon
peelply and mesh flow medium

The resin traveles along the UD (i.e. down the grain)

Has anyone seen this problem or have any suggestions?

thanks

tom

Carbon UD is a pig to infuse. Most of them that are succesful do not use a flow mesh, to slow down the resinflow. Some infuse at 90 degrees relative to the carbon UD, which also might be a solution for you. In that case the resin front is parallel to the carbon UD.

Thanks for your suggestions herman, will let you know how i get on. tom
