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 ...
With structural glued laminated bamboo as study object,we used two-component epoxy to study the pull-out strength of glued in rod,and tested the specimens in pull-pull configuration. We also studied the influence of edge distances,glue thickness and the slenderness ratio on pull-out strength. ...
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 ionic strength (salt concentration), choice of detergent, and pH of the lysis buffer may affect the immunoprecipitation efficiency as well as the integrity of the target antigen. Some common lysis buffers...
Results indicate that the gritimpregnated epoxy coating can provide bond strength similar to or greater than that of uncoated strand when the grit density is properly controlled. Although pullout specimen tests do not produce results identical to previously published values of bond stresses in the ...
4.3.3.2Pullout strength Thestrengthof bonding layer is subjected to both horizontal shear strength and vertical pullout strength. As the tack coat of overlayer onbridge deckor pavement, epoxy emulsifiedasphaltshould showstrong adhesionto avert the failure caused by the insufficientpullout resistance. ...
Pull-out strength of axially loaded steel rods bonded in glulam parallel to the grain Mater Struct (2006) R. Tomasi et al. Ductile end connections for glulam beams Structural Engineering International: J International Association for Bridge and Structural Engineering (IABSE) (2008) There are more ...
Moreover, the effects of the glass surface condition and the presence of a basalt mat layer within the adhesive thickness were evaluated. The mechanical performances were related with the occurred failure mechanisms. Epoxy-based joints showed higher strength and durability than the polyurethane based ...
In this study, copper-based leadframe sheets were oxidized in a brown-oxide and/or a black-oxide forming solution to improve the adhesion strength between the copper and the epoxy resin. The effects of the formation of oxides on the adhesion strength of leadframe to EMC were studied using ...
1.Moreover,the interfacial shearing strengths between PBO fiber and epoxy resin before and after the treatment were finally measured by the single-fiber pull-out test.采用氩气等离子体结合偶联剂技术对聚对苯撑苯并二噁唑(PBO)纤维进行表面改性,用SEM,XPS和液滴形状法对改性前后纤维表面的形态结构、组成...
