Hey Mike -

Glad you are back - sounds like you had a cool trip.

The image shows what S glass looks like next to E glass. Both came from JR Sweet and the only difference between the two styles is the glass type. Wet out of both went the same and was complete and there was no resin starvation. The only explanation that makes sense to me is the small difference between the index of refraction for S glass and E glass. I think part of what you see is the interference pattern created by having two layers. Since the two layers are not perfectly aligned, the visual effect is enhanced in some regions and reduced in others.

Just what is this triaxial stuff you have mentioned. The only commercial triaxials (three different fiber orientations) I'm familiar with are stitched, and heavy.
