By Elnaz Esmizadeh, Marjan Tanzif, Hossein Bazgir, Atena Nazari, Ali vahidifar

Abstract: ABSTRACTIn the present study, adsorptive properties of polyaniline/xanthan gum nanocomposite were investigated for methylene blue (MB) dye in aqueous solution. The effects of different parameters, namely adsorption time, adsorbent dose, pH and initial dye concentration were on dye adsorption were investigated. The results revealed that a rise se in pH lead to a significant increase in adsorption efficiency. Optimum adsorption time and nanocomposite dose were obtained 60 min and 0.075 …

Studies on Mechanical, Thermal Properties, Characterization and UV-Accelerated Weathering of HIPS-PLA Blends using Glycerol as Compatibilizer

By S Soundararajan, B Dinesh

Abstract: AbstractHIPS (High Impact Polystyrene) was blended with PLA (poly lactic acid) in three formulations as 80:20, 65:35 and 50:50% (wt%) using a twin screw extruder and by using glycerol (4%) as compatibilizer. Test specimens were prepared by using an injection moulding machine and the mechanical, thermal and electrical properties were determined. The tensile strength first decreases and then increases with increasing percentage of PLA, but lower than that of both …

An Overview on Carbon Fibre Reinforced Polypropylene

By Sanketh Yeli, Srikaanth G V

Abstract: AbstractThis review article describes the methods of fabrication of composites using carbon fibre and polypropylene and improving the mechanical properties of composites. Recycled carbon fibre/polypropylene (reCF/PP) wrap-spun yarns were compared to the virgin carbon fibre. The aim is to enhance the tensile properties of the CFRPP/SRPP intralayer hybrid composites under tensile stresses; observations of different kinds of weave patterns and layups are resulted. Keywords: Recycled carbon fibre, polypropylene, carbon fibre …

Capability Database of Injection Molding Process—Requirements Study for Wider Suitability and Higher Accuracy

By Boorla S Murthy, Tobias Eifler, Jens Dines O. Jepsen, Thomas J. Howard

Abstract: AbstractGenerally, there is little disagreement that an early consideration of dimensional accuracies achieved in production is conducive to the success of development of injection molding products. While different process capability databases (PCDBs) provide guidance for a meaningful estimation of the expected part variation, the adoption of corresponding guidelines and (proprietary) software tools seems to be, however, limited in industrial practice so far. This research paper addresses the gap between the …

Mathematical Modeling of the Flexural Strength, Impact Energy and Water Absorption of a Pineapple Fibre-HDPE Composite using RSM Technique

By B. Dan-asabe, A. A. Galadi

Abstract: AbstractA pineapple fibre reinforced HDPE composite was developed. Response surface methodology (RSM) experimental design was employed using the latest Design Expert 10.0 software and the sample composites were produced by compounding using two-roll mill and subsequent thermoformimg in a hot pressing machine. Mathematical models of the flexural strength, impact energy and water absorption were developed and statistically validated. The model for the flexural strength fitted best with quadratic model while …

Effect of Different Fibers on Mechanical Properties of Polypropylene

By Srikaanth G. V, Sanketh Yeli

Abstract: AbstractComposites have created a niche in today’s world market. Polypropylene is the second largely used plastic in the world. Polypropylene in its pure form cannot be used in many applications. Reinforcements are made into the pure polypropylene in order to enhance its mechanical properties. In the present paper, a review has been made on the recent advances for the various reinforcements being made into the polypropylene. The effect of fiber …
