Dry prepregs for ceramic matrix composites are described. The dry prepregs comprise a tow or fabric of ceramic fibers infiltrated with preceramic matrix comprising low levels of an aqueous solvent. The preceramic matrix contains an inorganic portion and a binder system. Binder systems comprising a binder and a plasticizer for the binder are described.

The present disclosure provides a resin blend containing a blend of a first phthalonitrile resin, a filler, and a bisphenol M diphthalonitrile ether resin. Suitable fillers include at least one of nanoparticles, microparticles, or fibers. The present disclosure also provides an article including a polymerization product of such a resin blend. The resin blends can be prepared at lower temperatures than phthalonitrile resin blends without a bisphenol M diphthalonitrile ether resin.
