Crosslinking polyamide oligomers are mixed with comparable, noncrosslinking, polyamide polymers to provide solvent-resistant blends that are particularly suited for aerospace uses. Generally, the blend comprises an equimolar mixture of the linear or multidimensional oligomer and a polymer having substantially an identical backbone and substantially the same average formula weight as the oligomer. Prepregs and composites of the blends can easily be prepared. |
