ABSrRAcr: Material properties of composites prOOuced from ruycled plastics and ruycled ~ fiber were compared. A blend of high -density polyethylene aIKi polystyrene was used as a simulated mixed plastic. Stift'ness was generally improved by the addition of fiber, as expected, but brittleness also increased. Pre-treatment of the ~ fiUer with phenol-fonna1~ resins did not significantly a~t materi...

A polyethylene/wood-fiber composite loaded with nano-ZnO was prepared by a facile hot-press method and was used for the photocatalytic degradation of organic compounds as well as for microwave absorption. ZnO nanoparticles with an average size of 29 nm and polyethylene (PE) powders were dispersed on the wood fibers' surface through a viscous cationic polyacrylamide (CPAM) solution. The reflecti...

In this investigation an elastic stress analysis is carried out a woven steel fiber reinforced thermoplastic cantilever beam loaded uniformly at the upper surface. The composite beam material consists of low density polyethylene as a thermoplastic (LDFE, f.2.12) and woven steel fibers. Granules of the polyethylene are put into the moulds and they are heated up to 160°C by using electrical resis...

the use of agriculture residues as filler in composites is increasing due to their strength, abundance and low cost. soya stalks show promising renewable natural fiber. in polyethylene composites the physical and mechanical properties (flexural resistance, tensile, impacted absorbed energy, water uptake and thickness swelling) was examined at different composites. the results showed that, the m...

OBJECTIVE The aim of this study was to compare and elucidate the differences in damage mechanisms and response of fiber-reinforced dental resin composites based on three different brands under flexural loading. The types of reinforcement consisted of a unidirectional E-glass prepreg (Splint-It from Jeneric/Petron Inc.), an ultrahigh molecular weight polyethylene fiber based biaxial braid (Conne...

Abstract: The Quasi-static mechanical properties of hybrid fiber (steel fiber and Polyvinyl alcohol (PVA) fiber) reinforced cementitious composites (HFRCC(SP)) were investigated by compressive and tensile experiments. The compressive strength, peak strain, elastic modulus and tensile strength are studied as compared with that of engineered cementitious composite (ECC). Study results indicate th...

AIM Aim of this in vitro study was to evaluate the resistance to fracture of vertically fractured and reattached fragments bonded with fiber-reinforced composites. MATERIALS AND METHODS Root canals of 45 teeth were prepared, and the teeth were intentionally fractured into two separate fragments. Control groups (n = 15 each) consisted unfractured teeth with instrumented and obturated. Fracture...
