hi

im loking at the pros and cons of pre preg as it cost more to bye but you don't need to bye the resin so does it work out the same price? obviously ill need to make an oven and vac pump but just wondering how it all works out




so give me your views on pre preg against resin infusion




cheers Rob 

It's just very hard to use and cut, more so when it's dry and you are preparing the laminate (pre preg Kevlar is easier). Unless you have a really specific reason for needing it then I always avoid it.

Once cured it will cut ok but leave you with a furry edge, if it comes through the surface of your parts with sanding then you get more fur and more painting issues too.

When I do use it I try to use very little of it and make sure it is not in your moulded outer layer, best put further into the laminate somewhere, for when you want a real resistance to punctures or tears etc.

PITA.
