prepreg supply

Anyone know of a supplier who would sell 15-20 yards of prepreg. Nothing special, sports equipment grade, 4x4 twill prefered, 2x2 ok.

I’ve got a ton of prepreg in the shop right now, but getting it to you would be the difficult part.
Are you prepared to pay for shipping it at 10*? Do you have proper a proper storage freezer? Might be tough to justify for such a small amount.

Prepreg must be kept below freezing temperature? Just asking not trying to be a smart alec.:slight_smile:

Yes. It needs to be transported and stored below freezing temp. We let it sit to thaw out before unrolling and cutting.

It also depends on the out-life of the fabric/resin. Some is shipped with dry ice, some doesn’t need it, especially in the winter.

AVT in Indianapolis sells it in small quantities.

Getting it isn’t the issue. People may not realize the other things needed to use prepreg.
It’s not a matter of simply deciding to use dry fabric and infuse, or use prepreg.
How about curing? Autoclave or oven? Is the tooling suitable for prepreg?

Hold on a minute! The origional question was where to get it. Where’s Clasic Bike when you need him, he’d tell you all you need is CSM, a bucket and a brush!

Haha, true. I’d love to see the parts he’s selling. If it works for him, then great. But the buyers must not know about composites.
I can’t imagine showing Boeing a part made with CSM and asking if they’ll buy it!

it depends on the prepreg system, but what happens when the prepreg is not in frozen state its working life slowly goes down, depending on the prepreg system it could be good for a couple days at room temp to up to a month or more. and when I say working life, I generally mean its tackyness and ease of use, and not so much the physical properties it might loose if any, once again depending on the prepreg resin system. The prepreg I was using would easily stay out it roomtemp for up to a month and cure with the same properties, but after a month it would be difficult to apply the first layer to the mold surface. and if you want to ship prepreg, ship it with dry ice

I know that the stuff isn’t the easiest to deal with. I’m working with small parts and prepreg should be much easier to work with in the actual making of the parts.
