Hello, 

I am looking for 6-10 oz/200g/m2 glass fiber prepreg (woven and UD) but all the ones I've found online are much higher in weight. Is prepreg not available in such low weight? I would be very grateful if any one can point me in the right direction.

Regards,
Aisha

Thanks Steve! The kompozitsan link looks like it is what i want but it doesnt mention the resin or the curing temperature, etc. have u used this before?

No, just a simple Google search :-)

     Often pre-pregs are listed by their total weight including resin, rather than just the fibre weight as dry fabrics are sold. So a 285g pre-preg is likely to be a 200g fabric unless stated otherwise.
Hanaldo - 7 Years Ago
             Easy composites weights are for the fabric only. All the prepregs I have bought have been listed as fabric weight so I have to add around 40% to the listed weight to calculate total weight.
Steve Broad - 7 Years Ago
     Yeh they dont all do it, which is where it gets confusing. The fiberglass pre-pregs I buy are listed as total weight, so thought it worth mentioning.
Hanaldo - 7 Years Ago
             Yeah, I was somewhat disappointed when I first found out that the posted weights didn't include the resin and I had to add 40% :-( Total weight seems the obviously figure to use, but I understand tha...

     Can anyone please shed some light on how u go about figuring the curing temp of the epoxy in the prepreg? Big companies usually mention them but some suppliers dont. For example the link below doesnt...
student00 - 7 Years Ago
     There is no way to figure it out, you need to contact the supplier.
Hanaldo - 7 Years Ago
             This is in no way a criticism, but it depends on the use the material is being put and the surface finish required. If the part being made is strength critical then, yes, you need the resin...

     There isn't such a thing as a "autoclave" resin system. Thou resin can be applied to carbon to make it OOA material,it's the same resin Most systems are the same an as Steve said experiment "Most"...
f1rob - 7 Years Ago
             I meant carbon fibre composite designed for autoclave :-) If the resins are the same, what is the difference between OOA and Autoclave composites? In order to use the autoclave composite I had to...
Steve Broad - 7 Years Ago
                 OOA just has the resin applied a different way "Traditional" pre preg goes through a resin bath,the cloth is totally saturated an then it goes through essentially a giant mangle. That squeezes out a....
f1rob - 7 Years Ago
                     So, let's see if I have got this :-) Prepreg is the original and required an Autoclave so is simply called prepreg. OOA was developed as an alternative so needs the OOA tag to differentiate it from....
Steve Broad - 7 Years Ago
     For a fair while back in the old days most curing was done in oven,not a autoclave in sight. Lot of invention then with cures,release film,breather ect to get a good part All the parts we are doing a...
f1rob - 7 Years Ago
             So, there is quite a lot of BS floating about. That's a fair squeeze, 6 times atmospheric :-) How much extra does that compress the material compared to 15psi?
Steve Broad - 7 Years Ago
     To be fair not that much more. Put a vernier on a piece of uncurred umaterial an that's the thickness you will get cured,be it 15psi or 90 Just loose a little bit on a ply stack with multiple layers....

             So, crucial for very high end stuff but not for the rest of us.
