Abstract Fiberglass-reinforced plastics (FRP) composite materials for ships that are widely used marine-grade unsaturated polyester resin matrix and combimat fiber, a combination of chopped strand mat (CSM) woven roving (WR) fibers. Although less popular than marine CSM–WR, biaxial warp-knitted glass fabrics have the potential to be applied as fiber laminates ship hull materials. A comparative ...

Abstract— A classical plane problem of the theory elasticity about a crack in stretched orthotropic elastic unbounded is considered, which leads to singular solution for stresses vicinity edge. The relations generalized elasticity, including small scale parameter, are given. equations higher order than and allow eliminating singularity solution. parameter determined experimentally. results obta...

Ellen Lackey, “Combined Effects of Moisture, Temperature, and Load on Pultruded Composites,” Technical Papers B CFA Composites 2002, CDROM, 2002. (Selected as Best Pultrusion Paper and Co-winner for Best Overall Paper for Composites ‘02) Brief Abstract: The objective of this study was to thoroughly document the effects of heat, moisture, and loading conditions on the properties of a polyester p...

The plate of a pultruded fiber-reinforced polymer or fiber-reinforced plastic (FRP) profile produced via a pultrusion process is likely to undergo local buckling and cracking along the fiber direction under an external load. In this study, we constructed a pultruded glass-fiber-reinforced polymer-light wood composite (PGWC) profile to explore its mechanical performance. A rectangular cross-sect...

The behavior of tapered graded-index polymer optical fibers is analyzed computationally for different refractive indices of the surrounding medium. This serves to clarify the main parameters affecting their possible performance as refractive-index sensors and extends an existing study of similar structures in glass fibers. The ray-tracing method is employed, its specific implementation is expla...
