Glass Fiber Composite Prepreg
Who makes qualified prepreg in this fiber and resin system, and what is the out-time?
What it is
Reinforcement pre-impregnated with a controlled fraction of partially cured resin, supplied frozen and with a finite out-time and shelf life. The dominant input for aerospace primary structure.
- Typical dimensions
- Tape from 0.125 to 12 inch width; broadgoods to roughly 60 inch width.
- Also known as
- pre-impregnated, tape, slit tape, broadgoods, thermoset prepreg, thermoplastic tape
Suppliers
Grouped by what they actually are. A mill and a distributor answer different needs.

Production methods
The same form, purchased as tolling on your own material.
Prepregging 3
Impregnating reinforcement with a controlled resin fraction and partially advancing the cure, then slitting and packaging under refrigeration. Qualification is per material system and per line.
