The tensile pull-outstrength of the composite rebar embedded in concrete was measured and compared tosteel rebar. Fiberglass/epoxy is less likely to corrode than steel rebar, ensuring moresustainable concrete structures in infrastructure applications.The 0.5" diameter composite rebar was produced by ...
Pullout, sliding and immediate fracture modes are observed; the fracture mechanisms depend on the CNT–epoxy interface strength and fiber strength, and ... BX Bie,JH Han,L Lu,... - 《Composites Part A Applied Science & Manufacturing》 被引量: 12发表: 2015年 Pull-out simulations of interfa...
Pull-off strength is a measure of the adhesive strength of a coating based on a pull-off test. The test involves adhering a dolly to the surface to be tested and pulling the dolly away from the surface, perpendicular to the surface. The pull-off strength is the result of this test base...
The pull-out strength was found to be almost directly proportional to the surface area of the bond line. Dependence between pull-out strength and anchoring length, slenderness ratio and diameter of the rod were examined. The influence of the wood density on the pull-out strength was verified....
As existing research on the pullout behavior of metallic anchors is partially relevant to FRP anchors, this paper first presents a review of current pullout strength models for metallic anchors. These models are then assessed with experimental data of FRP anchors and modified and recalibrated where...
Parametric study of factors affecting the pull-out strength of steel rods bonded into precast concrete panels This paper deals with the effect of bond thickness, embedment length and type of epoxy adhesive formulation on the adhesion of steel anchors to concrete. T... A Çolak - 《...
. In the present work, pullout tests were used to evaluate the interfacial shear stress of malva fiber in epoxy matrix composites. A small critical length was found for the malva fiber embedded in epoxy, which corresponds to a relatively weak fiber/matrix bond and lower interfacial strength....
multiple rods and rod spacing. A novel approach that involved end-profiling of the bond area was also investigated. It was found that epoxy adhesives out-performed all other types investigated, and pull-out strengths can be significantly improved through careful selection and optimisation of the jo...
