PROPreg is a prepreg that processes like the best of our aerospace prepregs. This carbon fiber + resin system is designed to imitate the properties, tack and match the superb out-life afforded by costlier prepregs but at an approachable price point. In some cases, our PROPreg might even beat a "qualified aerospace" prepreg!
You can use our prepregs any number of ways including, but not limited to, autoclave, press, vacuum, and compaction tapes. Since most shops do not have access to an autoclave or heated press, the latter two options are mostly used for smaller operations. Due to this prepreg’s specific uni-directional fiber orientation, you would use this prepreg in designs that need increased strength and stiffness in one direction. The fiber gives you medium stiffness, medium strength and maximum versatility.
Prepregs have special policies related to returns and shipping. Please review them here prior to order.
