The fast and thermal neutron attenuation properties through polymer composites based on high density polyethylene (HDPE) reinforced by micro-sized nano-sized Cadmium Oxide (CdO) particles with weight fractions of 10% 40% have been investigated. This study was carried out to present a new composite material HDPE filled CdO in the form micro nano be used as promising radiation shielding material....

Organic compounds such as benzene, toluene, ethyl benzene and o-, m-, and p-xylene from contaminated soil and groundwater may permeate through thermoplastic pipes which are used for the conveyance of drinking water in water distribution systems. In this study, permeation parameters of benzene in 25 mm (1 inch) standard inside dimension ratio (SIDR) 9 high density polyethylene (HDPE) pipes were ...

In this study, blends based on a high density polyethylene (HDPE) and chitosan (CS) were successfully prepared by melt processing, in a laboratory internal mixer. The CS biopolymer content effect (up to maximum of 40%), and, the addition of bentonite clay modified with quaternary ammonium salt (CTAB) impregnated chitosan as a compatibilizing agent, on the properties of the blends was analyzed b...

The objective of this study was to examine the effects of the hydroxyapatite (HA) reinforcement morphology and content on the fatigue behavior of HA reinforced high density polyethylene (HDPE). To this end, HDPE was reinforced with 20 and 40 vol% of either HA whiskers or an equiaxed HA powder, and tested in four-point bending fatigue under simulated physiological conditions. The fatigue life, m...

A question frequently asked about HDPEgeomembranes is “how long will they last?” After more than 30 years of experience with exposed (weathered) HDPE-geomembranes, the authors address the question from the designer’s view point. The engineer needs to know, if available test methods tell us how long the geomembrane will last, and which properties must be specified and what are the minimum accept...

The development of value-added products made from post-consumer plastic recyclates has become an important goal in the quest for a sustainable society. To attain such goal, tools with higher accuracy and wider scope are increasingly necessary. The present work describes the application of a Life Cycle Assessment (LCA)/Life Cycle Costing (LCC) integrated model, with inclusion of externalities (e...

Producing both hydrogen and high-value carbon nanotubes (CNTs) derived from waste plastics is reported here using a pyrolysis-reforming technology comprising a two-stage reaction system, in the presence of steam and a Ni-Mn-Al catalyst. The waste plastics consisted of plastics from a motor oil container (MOC), commercial waste high density polyethylene (HDPE) and regranulated HDPE waste contain...

The exploitation of natural fibers to reinforce polymers is a promising practice. Thus, biocomposites have gained increased attention in automotive, construction, and agricultural sectors, among others. present work reports the reinforcement recycled high-density polyethylene (r-HDPE) with hemp afford composite materials as sustainable analogues conventional wood/plastic (WPC) products. HDPE bo...

One of the main issues with Carbon Fiber Reinforced Thermoplastics (CFRTP) is poor impregnation quality matrix on carbon fiber due to high viscosity thermoplastic. Impregnation can significantly affect mechanical properties composite. This study aims compare abilities various types thermoplastic matrices fiber. The used in this are HDPE, PC, and PET. Three variations treatment were employed: fi...
