Abstract
Curable compositions comprising an epoxy mixture comprising a) an epoxy mixture comprising i) a first epoxy component comprising epoxy phenol novolac oligomers having a content of 2-functional monomers of less than 10 weight percent based on the total weight of the first epoxy component and having an epoxide equivalent weight in the range of 170 to 200; and ii) a second epoxy component comprising an epoxy resin having monomers with an average functionality of at least 2 and b) a hardener, are disclosed. The curable compositions can be used to prepare prepregs for hot-melt applications.
