Selective laser sintering (SLS), which is a additive rapid manufacturing technique, it is capable of producing the required product directly and automatically from a 3D computer model representation, have been selected to build implant and scaffold structures using composite materials consisting of a polymer and a bioactive ceramic. Hydroxyapatite (HA), a bioceramic that encourages bone apposit...

Recycling and reusing plastic waste are key options for ameliorating its negative effects on the environment economy. This paper proposes evolutionary polynomial regression (EPR) as a powerful technique to predict compressibility behavior of sand high-density polyethylene (HDPE) mixtures. In investigation, series large-scale oedometer experiments were conducted. The results coefficients lateral...

A novel wood flour (WF)-filled composite based on the microfibrillar high-density polyethylene (HDPE) and Nylon-6 co-blend, in which both in situ formed Nylon-6 microfibrils and WF acted as reinforcing elements, was successfully developed using a two-step extrusion method. At the 30wt.% WF loading level, WF-filled composite based on the microfibrillized HDPE/Nylon-6 blend exhibited higher stren...

Simultaneous thermogravimetry-mass spectrometry studies of a pyrolytic decomposition of mixtures of different plastic wastes/coking coal were carried out. The investigation was performed at temperatures up to 1000oC in a helium atmosphere under dynamic conditions at a heating rate of 25 oC/min. Five thermoplastics, commonly found in municipal wastes: low density polyethylene (LDPE), high densit...

Plastic Waste (PW) is one of the primary sources pollution, leading to drainage system blockages, thereby causing floods and road pavement damage. One major ways reduce pollution due plastic waste excessive exploitation natural resources through development HDPE. It also important damage structures by improving quality asphalt used during construction. Therefore, this research aims analyze effe...

The aim of this study is to investigate the kinetic characteristics high-density polyethylene (HDPE) waste pyrolysis process based on thermogravimetric analysis (TGA) and using a fixed bed pyrolytic reactor (FBPR) at different temperatures. In addition, influence material thickness yield distribution composition products was examined over temperature range 425–550°C. A higher wax fraction obtai...

The influence of different additives: high density polyethylene (HDPE), low density polyethylene (LDPE) and TiO2 nanoparticles on the polyethylene terephthalate (PET)–rubber nanocomposite interface was investigated. The composites obtained by compression moulding from tire rubber and PET bottles’ waste were partially heterogeneous and partially compatible, as confirmed by the FTIRmeasurements. ...

Composites based on high density polyethylene (HDPE), pine flour, and organic clay were made by melt compounding and then injection molding. The influence of clay on crystallization behavior, mechanical properties, water absorption, and thermal stability of HDPE/pine composites was investigated. The HDPE/pine composites containing exfoliated clay were made by a two-step melt compounding procedu...

The purpose of this study was to investigate the mechanical and thermal properties of high-density polyethylene (HDPE) composites reinforced by bamboo pulp fibers (BPF). Using a twin-screw extruder, polymer composites were fabricated using BPF and bamboo flour (BF) as the reinforcement and HDPE as the matrix. Tensile and flexural tests of the HDPE composites were performed to determine the mech...

This research paper proposes a sustainable and feasible technique to utilize seashell waste. The utilization of seashells offers economic environmental benefits because their abundant, renewable, cheap source calcium carbonate. will reduce the hazards waste generated environment landfilling that cause risk water sources public health. Moreover, synthesized bio − CaCO3 end-product cost polymer. ...
