Influence of Flexographic Photopolymer-Plate Residue Incorporation on the Mechanical Properties of Glass-Fiber-Reinforced Polyester Composites

In this study, the effects of incorporating recycled photopolymer-plate residues from a packaging flexography process into polyester-glass fiber composites were examined. Ternary with an unsaturated polyester matrix elastomer particles evaluated using two types glass fibers: in forms fabric bidirectional fibers and blanket multidirectional fibers. The prepared by hand lay-up lamination different rubber contents (0, 2.5, 5, 10 wt% based on resin mass fraction), characterized for their void content, flexural impact strengths, dynamic mechanical properties. Primary results indicated that incorporation increased difficulty lamination, while promoting greater formation higher filler content. decreased resistance properties but did not reduce strength or storage modulus, indicating despite elastomeric composition, residue photopolymer plates showed reinforcing rather than toughening character.
