Abstract
A study of the influence of UV radiation on the tensile properties of spider silk has shown that the shape of the stress-strain curves are not affected by 254 nm irradiation except for a significant decrease in the tensile strength and strain at breaking. This decrease has been found in both forcibly silked (FS) and maximum supercontracted (MS) fibers, despite the different initial alignments of the protein chains. Local damage was also induced by UV radiation. With this procedure it is possible to recover and analyse fracture surfaces. These show different granular microstructures which are characteristic of fibers spun from a solution.
