Carbon Fiber Prepreg

Prepreg moves resin control upstream: fiber and resin are combined under the supplier’s process control, so the moulder inherits a fixed resin content and a defined shelf life instead of mixing by hand. The trade is logistics — frozen storage, out-life clocks and cure cycles that must be respected. This collection covers prepreg systems, storage and handling, cure methods and out-of-autoclave qualification.
