Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A method for reinforcing the strength of the interface between a polymer fiber and a polymer matrix is described. PET fibers were etched in an oxidative plasma to generate a surface nanopattern. Depending on the plasma treatment time, lamellae patterns with different geometries were obtained. The interfacial shear strength (IFSS) between the fiber and a epoxy matrix was measured for the different surface topographies. A twofold increase in the IFSS was obtained for lamellae with 100 nm thickness, 300 nm height, and separated by 400 nm valleys. Our results demonstrate the benefit of a surface pattern for reinforcing the interface between fibers and resin. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1v9z6ps1" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
