Methods of fabricating composite articles and related articles and structures
Composite articles of manufacture and methods of making the same are provided herein. In one embodiment, a composite article includes a fiberglass component having a color of pantone 376C. Subjecting the fiberglass component to various environmental conditions result in the fiberglass component exhibiting a color of pantone 376C. Thus, the fiberglass component does not fade and become lighter or hazy in appearance, but takes on an appearance of deeper hue and/or saturation, providing longer life of the appearance of the fiberglass component.
1. A ladder comprising:
a pair of rails; and
a plurality of rungs extending between, and coupled to, the pair of rails;
wherein at least one rail of the pair of rails includes a fiberglass material having a color of pantone 376C;
wherein the fiberglass material is configured to change to a color of pantone 383C after exposure to ultraviolet light.
2. The ladder of claim 1 , wherein the fiberglass material includes a polyurethane resin.
3. The ladder of claim 2 , wherein the polyurethane resin comprises polyol and isocyanate.
4. The ladder of claim 1 , wherein the at least one fiberglass component exhibits a minimum absorbance of light at a wavelength of approximately 536 nm.
5. The ladder of claim 1 , wherein the at least one fiberglass material is configured to change to the color of pantone 383C after exposure to about 1000 hours of ultraviolet light.
6. A ladder comprising:
a rail;
a plurality of rungs coupled with the rail;
wherein at least one of the rail and a rung of the plurality of rungs comprises a fiberglass material having a minimum absorbance of light having a wavelength of about 536 nm;
wherein upon exposure to ultraviolet light, the minimum absorbance is configured to shift to about 558 nm or to about 560 nm.
7. The ladder of claim 6 , wherein the fiberglass material includes a polyurethane resin.
8. The ladder of claim 7 , wherein the polyurethane resin comprises polyol and isocyanate.
9. The ladder of claim 6 , wherein absorbance of light in the ultraviolet spectrum of the at least one fiberglass material decreases upon shifting of the minimum absorbance.
10. The ladder of claim 9 , wherein the decrease in the absorbance occurs at or about a wavelength of light of 236 nm or 238 nm.
11. The ladder of claim 9 , wherein the ultraviolet spectrum includes light having a wavelength of about 300 nanometers or less.
