1. An injection process for a combustible foam thermoset part, comprising:
providing a quantity of an azido bearing polymer;
providing a quantity of a propargyl bearing curing agent;
providing a mold defining a male cavity, a female cavity, and an injection port;
mixing together the azido bearing polymer and the propargyl bearing curing agent to form a curable thermoset composition;
adding a foaming agent to the curable composition; and
injecting the resulting mixture into the mold, thereby preparing a combustible foam thermoset part.
