1. A method for forming composite articles comprising thermoset silicon-containing polymers, comprising:
(a) providing a first composition comprising a first thermoset silicon-containing polymer;
(b) providing a thermoplastic composition;
(c) printing, using an additive manufacturing device:
(i) a first at least partial layer of the first composition comprising the first thermoset silicon-containing polymer using an additive manufacturing device; and
(ii) an at least partial reinforcing layer comprising the thermoplastic composition, wherein the first at least partial layer of the first composition comprising the first thermoset silicon-containing polymer and the at least partial reinforcing layer are printed either to be within the same layer or in successive layers.
