the load transfer mechanisms of cable bolts differ from those for normal rebar bolts. the cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. the tendon strength can be evaluated by the tensi...

This paper is on modeling and measuring fiber-bridging constitutive law of Engineered Cementitious Composites (ECC), a high performance fiber-reinforced cementitious composite featuring high tensile ductility. Fiber-bridging constitutive law plays an important role in the multiple cracking behavior of ECC. Therefore, proper control of fiberbridging behavior through tailoring material microstruc...

The purpose of this study was to evaluate the bond strength at the post/resin-cement interface with 3 different surface treatments of glass fiber posts and with 2 different luting resin cements. Sixty glass fiber posts (RelyX Fiber Post) were randomly divided into 3 groups (n = 20) and were luted with a dual-polymerizing self-adhesive universal resin cement (RelyX Unicem) and with a dual-polyme...

Spinal disorders cover a broad spectrum of pathologies and are among the most prevalent medical conditions. The management these health issues was noted to be increasingly based on surgical interventions. fixation devices often employed improve surgery outcomes, increasing spinal stability, restoring structural integrity, ensuring functionality. However, currently used tools fabricated from mat...

This study aimed to develop an extrusion and pultrusion system for producing carbon fiber-filled thermoplastic pellets. The extruder delivers a plastic melt impregnation die in sufficient volume is pulled out along with the fibers. fibers pass sideways stretched condition through spreader pins attached pool, which can then be wetted optimally. wetting effect was also improved by immersing fiber...
