Composites Manufacturing Laboratory

Our composites manufacturing lab is located on the first floor of the Science Engineering Research Facility (SERF) in rooms 153 (manufacturing) and 138 (autoclave).

The majority of our composites manufacturing involves graphite/epoxy prepreg (graphite fibers preimpregnated with epoxy matrix). We have a walk-in freezer to store the prepreg until it is ready to be used, a manufacturing lab to cut the prepreg and lay up the composite, and a hot-press and autoclaves for curing.

The prepreg composite, which is stored in the walk-in-freezer, is first cut in the manufacturing lab.

Sample composite lay-up

Single unidirectional prepreg ply

Peel Ply - gives surface its finish
Release Film - doesn't adhere to epoxy, thus allowing for removal of part
Breather - allows vacuum to reach entire part

Typical bagging sequence used before the composite can be placed within the autoclave.

The composite pieces are then cured in one of the Autoclaves.
