    Photoelastic evaluation of fiber surface-treatments on the interfacial performance of a polyester fiber/epoxy model composite
    (Elsevier, 2011-08-01) Flores-Johnson, EA; Vázquez-Rodríguez, JM; Herrera-Franco, PJ; González-Chi, PI
    The interfacial adhesion between a polyester fiber and an epoxy matrix was improved by chemical and topological modifications of the fiber surface. The maximum interfacial shear strength was measured using photoelasticity to assess the interfacial performance in pull-out single-fiber composite specimens. An increase of the interfacial shear strength was observed when plasma-treated or surface-modified fibers were used: also, as the applied load to the free fiber was increased, the fiber treatment caused a reduction of the debonded area at the fiber-matrix interface.
