Abstract: A composite manufacture includes an extrudable thermoplastic matrix and a photochromic colorant, the photochromic colorant conferring to the composite a reversible strain-induced color change property. Methods include adding photochromic colorant to an extrudable thermoplastic polymer matrix to form a mixture, heating the mixture to form a composite, the photochromic colorant conferring to the composite a reversible strain-induced color change property. The composite manufactures can be used in cable coatings permitting visual detection of mechanical stresses in a wire based on the reversible strain-induced color change property.
