Physical and Mechanical Properties of Iron Powder Filled Polystyrene Composites

Abstract

This article reports on an experimental study of the physical and mechanical properties of Polystyrene (PS) and Fe-PS polymer composites containing 5, 10, and 15 vol.% of Fe powder. After mixing Fe powder and PS in a twin-screw extruder, an injection-molding machine was used to prepare unfilled PS and Fe-PS polymer composite samples. After that, the material properties were experimentally determined for each sample. The investigated material properties included the modulus of elasticity, yield and tensile strength, % elongation, Izod impact strength (notched), hardness (Shore D), melt flow index (MFI), heat deflection temperature (HDT), Vicat softening point, and glass transition temperature (T g ). The results indicated that, compared to the unfilled PS, an addition of Fe into PS decreases the yield and tensile strength, % elongation, and Izod impact strength. Furthermore, it was determined that the Fe particles increase the modulus of elasticity, hardness, MFI, Vicat softening point, and HDT values.

Optical and electrical properties of polystyrene composites containing ultrafine iron particles

“…Costa et al 14 reported that the large difference between conductivities of iron particles and PS promotes defect charges in the interfaces, which are loosely bound and are responsible for the electrical conductivity behavior at lower concentrations. Taşdemir and Gulsoy 15 reported that the physical properties are affected by adding the iron particles to the PS matrix. Recently, Elimat et al 16 studied the effect of iron particle sizes on the thermal conductivity of PS composites and found large enhancement in the thermal conduction.…”

Effect Of Steel Scale On The Physical Properties of Acrtlonitrile Butadiene Styrene (ABS) Copolymer

“…Yani artan konsantrasyon ile birlikte malzemenin erime entalpisi artmış böylelikle bozunma entalpisi yükselmiştir. Çalışmamıza benzer şekilde Gülsoy ve Taşdemir (Gülsoy ve Taşdemir, 2006); polipropilen matris içerisine demir tozu ilavesiyle kompozitlerin fiziksel özelliklerini incelediği çalışmasında artan demir miktarı ile HDT ve vicat sıcaklıklarının arttığını gözlemlemiştir. Şekil 4C'de verilen nem testi sonuçları incelendiğinde; tufal ilavesiyle nem oranını azaldığı dolayısıyla neme karşı direnç kazandığı görülmektedir.…”
