the effect of impact modifier on creep behavior of wood flour- recycled polypropylene composites has been evaluated in this work. for this purpose, impact modifier (ethylene vinyl acetate) and recycled polypropylene were mixed with wood flour (50/50% w/w) as well as the impact modifier (0, 3%, 6% and 9%) by a counter-rotating twin-screw extruder to manufacture the wood flour- recycled polypropy...

in this investigation, the mechanical properties of the blends of blown bitumen110/10, heavy vacuum slops (h.v.s), bitumen 60/70 penetration grade and isotactic polypropylene (ipp) were studied for the first time. our results showed that modulus varies non-linearly and at certain asphaltenes contents a peak appears. considering these phenomena it is revealed that in the absence of ipp, interact...

This work investigates the feasibility of using recycled high density polyethylene (rHDPE), recycled polypropylene (rPP) and old newsprint fiber (ONP) to manufacture fiber reinforced composites. The boards were made through air-forming and hot press. The effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...

In this work, post-consumer polypropylene and wood flour from Pinus elliottii were used to produce wood plastic composites. The effect of polypropylene grafted with itaconic acid used as a coupling agent on mechanical properties, thermal stability and morphology of the composites was investigated and compared with the composite developed with polypropylene grafted with maleic anhydride, commonl...

in this research, old magazine (omg) recycled fiber and glass fiber (gf) were mixed at different levels of 10%, 20%, 30% and 40% (based on weight) with two levels of 50% and 60% polypropylene (pp) and then the produced composites evaluated compared to those from net polypropylene. on the basis of obtained results from normalization equations in different treatments done, two treatments has been...

The industrial wastes fly ash (FA) and polypropylene (PP) were used to develop novel green composites using a renewable, cheap coupling agent i.e. stearic acid. The fly ash (FA) particles were coated with stearic acid (SA) in different weight % like 0, 1, 2, 3 and 5. The SA coated fly ash particles were incorporated as filler in recycled polypropylene (RPP) matrix which was obtained from post-c...
