Previous works have established the response and failure behaviour of hybrid (CFRP-GFRP) laminates when subjected to a wide range destabilising loads. However, date no focused on plates with cut-outs under shear loading quantified influence selective laminate shapes hybridisation their post-buckling response. Herein, plate collapse novel X-braced twill woven containing large circular cut-out (d...

–The paper presents the results of a study on the performance of Glass Fibre Reinforced Polymer (GFRP) wrapped high strength concrete columns under uni-axial compression. The columns had slenderness ratios of 8, 16, 24 and 32. Three types of wrap materials (Chopped Strand Mat GFRP, Uni-Directional Cloth GFRP and Woven Roving GFRP) were used with 3 mm and 5 mm thicknesses. The columns were teste...

OBJECTIVE In our previous study, glass-fiber-reinforced plastics (GFRPs) made from polycarbonate and glass fibers were prepared for esthetic orthodontic wires using pultrusion. These laboratory GFRP wires are more transparent than the commercially available nickel-titanium wire; however, an investigation of the color stability of GFRP during orthodontic treatment is needed. Accordingly, in the ...

The study of the mechanical interaction among the host, interface, and a device embedded within a laminated composite is important. Embedding micro-sensors in composite laminates produces material discontinuity around the inclusions. This in turn produces stress concentrations at or near the inclusions. Both 2D plane strain and 3D FEM models are developed to analyze the stress/strain state surr...

Advanced composites are not without a trade-off. Their increased designability brings an increase in the complexity of their internal geometry and, as a result, possible modes of failure. When two or more isotropic materials are combined in a composite, the isotropic failure modes may also combine. In a laminate, matrix delamination, cracking and crazing, and voids and porosity, will often comb...

15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. Project Title: Long-Term Performance of GFRP Reinforcement URL: http://tti.tamu.edu/documents/0-6069-1.pdf 16. Abstract Significant research has been performed on glass fiber-reinforced polymer (GFRP) concrete reinforcement. This research has shown that GF...

The penetration of a 30CrMnMo ultra-high molecular weight polyethylene armor by a high-speed fragment was investigated via experiments and simulations. Analysis of the projectile revealed that the nose (of the projectile) is in the non-equilibrium state at the initial stage of penetration, and the low-speed regions undergo plastic deformation. Subsequently, the nose-tail velocities of the proje...

Glass fiber reinforced polymer (GFRP) composite pipes are mostly used in transmission lines of submarine oil, natural gas, and chemical fluids. The alterations mechanical characteristics applications great importance to the lifespan material. Some important properties materials density hardness value. In this study, changes values GFRP which were unexposed seawater exposed for 1, 2 3 months inv...
