1. A co-curable UV/visible light-resistant composite material assembly consisting of:
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 fiberglass single ply layer, said co-curable UV/visible light-resistant fiberglass single ply layer comprising a co-curable UV/visible light-resistant fiberglass layer first side and a co-curable UV/visible light-resistant fiberglass layer second side;
wherein the co-curable UV/visible light-resistant fiberglass single ply layer has a UV/visible light transmittance value ranging from about 0% to about 20% UV/visible light transmittance for UV/visible light wavelengths ranging from about 200 nm to about 800 nm when the co-curable UV/visible light-resistant fiberglass single ply layer comprises an average thickness ranging from about 2 mils to about 6 mils;
wherein the co-curable composite material substrate second side is in direct contact with the co-curable UV/visible light-resistant fiberglass single ply layer first side to form the co-curable UV/visible light-resistant composite material assembly, said co-curable composite material substrate is co-curable with the co-curable UV/visible light-resistant fiberglass single ply layer at a temperature ranging from about 250° F. to about 370° F.;
wherein the co-curable UV/visible light-resistant fiberglass single ply layer immediately contacts and completely covers the co-curable composite material substrate second side;
wherein the co-curable UV/visible light-resistant fiberglass single ply layer is solely responsible for imparting UV/visible light-resistance to the co-curable UV/visible light-resistant composite material assembly; and
wherein the co-curable UV/visible light-resistant composite material assembly does not contain an additional UV/visible light-resistant material beyond the co-curable UV/visible light-resistant fiberglass single ply layer.
