1. A co-curable composite material fuselage assembly comprising:
a co-curable composite material substrate, said co-curable composite material substrate comprising a co-curable composite material substrate first side and a co-curable composite material substrate second side;
a co-curable UV/visible light-resistant coating layer, said co-curable UV-resistant coating layer comprising a co-curable UV/visible light-resistant coating layer first side and a co-curable UV/visible light-resistant coating layer second side, only said co-curable UV/visible light-resistant coating layer configured to be in immediate contact with at least one of the co-curable composite material substrate first side and the co-cured composite material substrate second side, said co-curable UV/visible light-resistant coating layer consisting of a single ply layer co-curable UV/visible light-resistant coating layer, said co-curable UV/visible light-resistant coating layer exclusively imparting 100% of a degree of UV/visible light protection imparted to the co-curable composite material substrate by the co-curable UV/visible light-resistant coating layer, said co-curable UV/visible light-resistant coating layer comprising at least one of fiberglass fibers, carbon fibers, polyester fibers, aramid fibers, boron fibers, quartz, and combinations thereof;
wherein the co-curable UV/visible light-resistant coating layer has a UV/visible light transmittance value of 0% to about 20% for UV/visible light wavelengths ranging from about 200 nm to about 800 nm when the co-curable UV/visible light-resistant coating layer comprises an average thickness ranging from about 2 mils to about 6 mils;
wherein the co-curable composite material substrate in combination with the co-curable UV/visible light-resistant coating layer is configured to form a co-curable composite material fuselage assembly;
wherein the co-curable composite material substrate is co-curable with the co-curable UV/visible light-resistant coating layer at a temperature ranging from about 250° F. to about 410° F. to form a co-cured composite material fuselage assembly in a co-cured state;
wherein the co-curable composite material substrate second side is in direct contact with the co-curable UV/visible light-resistant coating layer first side;
wherein the co-curable UV/visible light-resistant coating layer completely covers the co-curable composite material substrate second side; and
wherein the co-curable composite material substrate assembly does not contain an additional UV/visible light-resistant layer.
