Many natural and synthetic polymers are attacked by ultraviolet radiation, and products using these materials may crack or disintegrate if they are not UV-stable. The problem is known as UV degradation, and is a common problem in products exposed to sunlight. Continuous exposure is a more serious problem than intermittent exposure, since
“Right now we are testing a newly patented fire-resistant, carbon-fiber fabric used to increase the load-carrying capacity of precast and reinforced concrete beams.” Another research initiative at CIMR is the testing of 7,000 psi precast American Association of State and Highway Transportation Officials (AASHTO) I- and T-beams reinforced with a patented ductile-hybrid CFRP fabric.
