WebApr 1, 2004 · The load slip curves highlight some of the fundamental differences between steel and FRP materials. This paper reports in detail on the influence of various parameters that affect bond strength and development such as the embedment length, type, shape, surface characteristics, and diameter of the bar as well as concrete strength. WebJul 23, 2003 · When considering polymer adhesion it is important to recognise that the bulk mechanical properties of the polymer control the type of interfacial forces required for good adhesion. High adhesion can only be obtained if the interface can sustain sufficient stress to induce dissipative forms of deformation, such as flow, yield or crazing, in the polymer.
