“…Determination of flexural characteristic is important to overcome certain practical problem in measuring tensile characteristic of polymeric materials in brittle region. In particular, many polymer‐based products are used in applications where flexural properties are important, such as structural application, load‐bearing applications, automotive, piping, and others .Therefore, in this study, the flexural strength and flexural modulus of tested hybrid composites were measured as illustrated in Fig. .…”

The effects of hybrid fillers on thermal, mechanical, physical, and antimicrobial properties of ultrahigh-molecular-weight polyethylene-reinforced composites

The effects of hybrid filler of zinc oxide and chitosan (chitosan-ZnO) on thermal, flexural, antimicrobial, chemical resistance, and hardness properties of ultrahighmolecular-weight polyethylene (UHMWPE) composites with varying concentration of zinc oxide (ZnO) and further hybridized by chitosan (CS) were successfully studied. The composites were prepared using mechanical ball milling and followed by hot compression molding. The addition of ZnO to the UHMWPE matrix had lowered the melting temperature (T m ) of the composite but delayed its degradation temperature. Further investigation of dual filler incorporation was done by the addition of chitosan to the UHMWPE/ZnO composite and resulted in the reduction of UHMWPE crystallization. The flexural strength and modulus had a notably high improvement through ZnO addition up to 25 wt% as compared to neat UHMWPE. However, the addition of chitosan had resulted in lower flexural strength than that of 12 wt% ZnO UHMWPE composite but still higher than that of neat UHMWPE. It was experimentally proven that the incorporation of ZnO and chitosan particles within UHMWPE matrix had further enhanced the antimicrobial properties of neat UHMWPE. Chemical resistance was improved with higher ZnO content with a slight reduction of mass change after the incorporation of chitosan. The hardness value increased with ZnO addition but higher incorporation of chitosan had lowered the hardness value. These findings have significant implications for the commercial application of UHMWPE based products. It appears that these hybrid fillers (chitosan-ZnO)-reinforced UHMWPE composites exhibit superior overall properties than that of conventional neat UHMWPE. POLYM. COMPOS., 00:000-000, 2015.

“…For example, ultra-high molecular weight polyethylenes (UHMWPE) having a molecular weight (M w ) greater than 3 000 000 possess excellent abrasion resistance and impact strength, very low coefficient friction, good self-lubricants properties, as well as good resistance at low temperature [1][2][3][4][5][6][7][8]. Polyethylenes with broad or multi-model molecular weight distribution (MWD) can meet the requirement for good resin processability, since they show high workability due to the high molecular weight (HMW) fractions, and at the same time they provide excellent mechanical properties due to the low molecular weight (LMW) fractions [9,10].…”

“…A larger drill bit is used to countersink the bolt heads on the top piece of the imaging sample to provide a smooth top surface. UHMW-PE is an exceptionally high molecular weight thermoplastic that is extremely abrasion, impact and chemically resistant, the highest among plastics [54].…”

“…Due to its selflubrication and impact resistant properties, it has been originally used in the handling of bulk materials like grain, cement and gravel, as well as in the mining industry. UHMW can be used in dumping trucks, silos, large bins, conveyor systems, chutes, dry bearings, and so forth [54]. UHMW combined with other substances, such as oil, can be crafted into a fibrous form, which is found in bulletproof vests and protective gloves.…”

Terahertz reflection time-domain spectroscopy for imaging and identifying concealed interfaces in multilayered systems

This thesis reviews multiple forms of terahertz spectroscopy and imaging, and exploits a combination of aspects from the techniques involved to undertake a novel method. With the use of this method, subsurface interfaces within a practical, insulated system are spatially imaged and identified. Initially, transmission spectroscopy is used to select the insulating material of the system based on favourable dielectric properties, followed by the use of dove prism reflection spectroscopy to understand and qualitatively contrast the responses of the interfaces to reflecting terahertz pulses. After constructing a reflection imaging system, multiple interface materials concealed by insulation are successfully located and identified by coloured overlays in a 100 by 100 image. Further exploration of applications involving the proposed method is also discussed.
