So let’s say I have this wonderful 20pound roll of AS-4 unidirectional pre-preg tape.
Anyone want to play with some?
Disclaimer: It’s polyetherimide.
I’d give it a try. Need to make some strong tubes. Is it epoxy compatible?
i’d like to try some. are there instructions with it?
Does it require a heated press to mold?
KnottyBuoyz, no it isn’t. It’s a thermoplastic pre-preg. It’s like a stiff plastic sheet. (well, obviously only in the fiber direction)
Everyone else. Yes, i would include some plastic instructions, and yes it needs heat of some sort.
