I’m about to test some parts made from prepreg material and I’d like to produce our own prepreg similar to the method in David Algie’s now famous video. If I understand correctly, I can obtain a b-stage cure with our existing array of epoxies and vinyl ester resins simply by changing the catalyst??? Can anyone using this method of DIY prepreg production recommend a good epoxy and catalyst to use?
I am sorry but what David does is not prepreg. It is wetpreg. It is not bad, it is just not prepreg.
Prepreg resin will not flow at room temp.
Also the resins used in prepreg are not the same as used in wet layup.
Sorry. Can anyone recommend a good wetpreg epoxy system that will cure to a b-stage?
sicomin has some, no experience, but sicomin resins are top notch in general.
Sicomin SR 121 looks like it could be promising. Now I just need to find it in the US 
Has anyone here tried MAX HTE from Polymer Composites Inc?
haven’t try it myself.
but it certainly is interesting
