Abstract: The present technology relates to composites, apparatuses, systems, and methods that are based on a photocurable composite useful for stabilizing, supporting, or otherwise healing an injured limb. The photocurable composite includes a light-curable resin and a filler material, where the light-curable resin includes about 50 vol % to about 99 vol % (based on the volume of the light-curable resin) of an acrylate-functionalized oligomer, wherein the backbone of the oligomer comprises a polyurethane, a polyether, a polyester, or a combination of any two or more thereof; about 1 vol % to about 50 vol % of a radical-reactive diluent; about 0.001 vol % to about 2 vol % of a photoinitiator; and optionally about 0.05 to about 25 vol % of a surface cure protection agent.
