Abstract:

Ultra-high molecular weight polyethylene-based self-reinforced composite materials were studied. Surface of the ultra-high molecular weight polyethylene fibers was modified by direct fluorination and nitric acid treatment. Structure and mechanical properties of self-reinforced ultra-high molecular weight polyethylene depending on the content and type of modified fibers were studied. It was shown that self-reinforcing of ultra-high molecular weight polyethylene allows to obtain materials with improved strength–elastic properties. Tensile strength and Young’s modulus of the self-reinforced composite materials are more than three times higher than that of the unfilled ultra-high molecular weight polyethylene.

Abstract:

Ultra-high molecular weight polyethylene has a low X-ray attenuation, hence, the performance of the polyethylene implants used for joint replacements cannot be directly investigated using X-ray-based imaging techniques. In this study, the X-ray attenuation of polyethylene was increased by diffusing an FDA-approved oil-based contrast agent (Lipiodol ultra fluid) into the surface of the samples, and the suitability of this novel radiopaque ultra-high molecular weight polyethylene for clinical applications was examined. Different levels of radiopacity were created by controlling the diffusion parameters, and the level of radiopacity was quantified from computed tomography scans and reported in Hounsfield units. The physical, chemical and tensile properties of the radiopaque ultra-high molecular weight polyethylene were examined and compared to untreated and thermally treated controls. The results of this study confirmed that for the samples treated at 115°C or less the diffusion of the contrast agent did not significantly alter the crystallinity ( p = 0.7) or melting point ( p = 0.4) of the polyethylene. Concomitantly, the tensile properties were not significantly different from the control samples ( p > 0.05 for all properties). In conclusion, the radiopaque ultra-high molecular weight polyethylene treated for less than 18 h at a temperature of 115°C or below is a promising candidate for joint replacement applications as it can be identified in a standard X-ray while retaining the tensile properties of clinically used radiolucent ultra-high molecular weight polyethylene.

Abstract:

Abstract Ultra-high molecular weight polyethylene is a kind of popular engineering material because of its unique properties stemming from high molecular weights. Nowadays, the preparations and applications of this type of material are widely researched. This review mainly focuses on the preparation of ultra-high molecular weight polyethylene using three types of typical catalysts (heterogeneous Ziegler-Natta catalysts, Fujita’s catalysts and α-Diimine Nickel (II) catalysts) and applications in two significant areas (bulletproof membranes and lithium-ion batteries). Ziegler-Natta catalysts and Fujita’s catalysts favor the synthesis of linear ultra-high molecular weight polyethylene, but α-Diimine Nickel (II) catalysis favors β-hydride elimination which leads to branched products. Changes in steric, composition, activators, temperature and pressure will affect the tendency towards different mechanisms and influence structures and properties of final products.

Abstract:

A great deal of research and development work has been recently conducted on natural fiber-reinforced polymer matrix composite for its abundancy, low density, excellent damping characteristic, and good mechanical properties. However, the low strength of natural fiber composite has limited its use to only low stress applications. The purpose of this work is to develop a natural fiber hybrid material with both enhanced strength and failure strain using a novel approach and study the effect of the processing temperature on its microstructure and performance. High-strength ultra-high molecular weight polyethylene fabrics are co-molded onto the surfaces of a kenaf fiber high-density polyethylene-based composite material by single-step compression molding. The status of the ultra-high molecular weight polyethylene fabrics at different processing temperatures is investigated using microscopic analysis. The tensile strength and impact strength of the hybrid material are evaluated. It is found that its tensile strength is increased by more than 90% with only 8% ultra-high molecular weight polyethylene fiber reinforcement added and its low density is maintained.

A study of the compatibilization of polyamide (PA)/ultra high molecular weight polyethylene (UHMWPE) blends by reactive processing has been initiated. Attention has been focused on the effect of compatibilization on the morphology and the mechanical and thermal behaviour of the resulting blend systems. A triblock copolymer, functionalized with maleic anhydride, has been found to have a profound effect on the properties of the blends. Compatibilized PA/UHMWPE blends combining the desirable properties of the two basic polymers will offer considerable development potential.

Abstract:

Wear tests were carried out on reciprocating pin-on-plate machines which had pins loaded at 10 N and 40 N. The materials tested were irradiated cross-linked polyethylene sliding against itself, irradiated ultra-high molecular weight polyethylene sliding against itself and non-irradiated ultra-high molecular weight polyethylene sliding against itself. After 153.5 km of sliding, the non-irradiated ultrahigh molecular weight polyethylene plates and pins showed mean wear factors under 10 N loads, or a nominal contact stress of 0.51 MPa, of 84.0 × 10−6 mm3/N m for the plates and 81.3 × 10−6 mm3/N m for the pins. Under 40 N loads, or a nominal contact stress of 2.04 MPa, the non-irradiated ultra-high molecular weight polyethylene pins sheared at 22.3 km. At the last measurement point prior to this failure, 19.1 km, wear factors of 158 × 10−6mm3/N m for the plates and 85.0 × 10−6 mm3/N m for the pins had been measured. After 152.8 km, the irradiated ultra-high molecular weight polyethylene plates and pins showed mean wear factors under 10 N loads of 59.8 × 10−6 mm3/N m for the plates and 31.1 × 10−6 mm3/N m for the pins. In contrast, after 150.2 km, a mean wear factor of 0.72 × 10−6 mm3/N m was found for the irradiated cross-linked polyethylene plates compared with 0.053 × 10−6 mm3/N m for the irradiated cross-linked polyethylene pins.

Abstract:

This study introduced trimethylolpropane trimethacrylate into ultra-high molecular weight polyethylene fibers through supercritical CO2 pretreatment before the fibers were irradiated under an electron beam. Significant differences, emerging in the ultra-high molecular weight polyethylene fibers’ gel content, mechanical properties, and creep property according to their different irradiation doses, were studied through one-way analysis of variance. Regression equations were established between the irradiation dose and the gel content, breaking strength, elongation at break, and creep rate by regression analysis. A reasonable irradiation dosage range was determined after a verification experiment and the impact trends were analyzed; additionally, the sensitized irradiation crosslinking mechanism of ultra-high molecular weight polyethylene fibers was preliminarily examined. Then the surface morphology, chemical structures, thermal properties, and crystal properties of treated ultra-high molecular weight polyethylene fibers were measured. The results showed that as the irradiation dose increased, the gel content first rose and then declined; the breaking strength decreased continuously; the elongation at break increased at first and then decreased; and the creep rate originally fell and then rose before finally declining slowly. Electron beam irradiation had a significant etching effect on the fibers’ surface, and both the melting point and crystallinity decreased slightly.

Abstract:

Ultra high molecular weight polyethylene (UHMWPE) is widely used in many orthopedic applications because of its good mechanical properties and excellent biocompatability. Mechanical properties are related to its ultra-high molecular weight, but the presence of defects in morphology will cause a decrease in these properties. The aim of this study was to characterize the microstructure and microchemistry of so-called “fusion defects”, observed by optical transmission microscopy, using SEM along with EDXS analysis. The fractured surface of UHMWPE was also studied.Defects similar to those found in commercially prepared UHMWPE were detected in the hot-pressed and extruded samples prepared at U-Mass Lowell using GUR 412. They consist of holes or cavities and sometimes appear to be circular in shape and are composed of variously sized small holes. The size of the defects is around 100 μm in diameter which is similar to the particle size of the raw powders.

Abstract:

Ultra-high molecular weight polyethylene (UHMWPE) is a polyethylene with a very long chain, which provides excellent features, however it makes the processing difficult due to high melt viscosity. Many studies intend to found out means to make its processing easier. Recently, the high-energy mechanical milling has been used for polymeric materials and it was detected that physical and chemical changes occur during milling. In such case, powder of UHMWPE was milled in three types of mills: SPEX, attritor e planetary, in different times of milling. The polymer was characterized by SEM and XRD. Thus, it was observed that the material processed in attritor mill showed larger phase transformation from orthorhombic to monoclinic. This is most likely due to the smaller milling temperature of attritor mill when compared with the other two mills and the high shear force generated during milling.

Abstract:

The paper investigates the influence of the content of Al-Ni alloy quenched from the molten state on the abrasive wear rate of ultra-high-molecular-weight polyethylene on rigidly attached abrasive particles. Studies have shown that the addition of 5–30 mass% of the quenched aluminum alloy to ultra-high-molecular-weight polyethylene reduces the rate of abrasive wear by ~50%. The improvement of this indicator is due to the high values of microhardness, dislocations density, and microstresses of rapidly quenched Al-Ni alloys.

Abstract:

Modern polymeric materials have a lower coefficient of friction with sufficient strength and wear resistance, which allows them to be used for the manufacture of working parts. This paper presents the results of laboratory studies of the traction resistance of the working part of a tillage machine with a polymer coating of ultra-high molecular weight polyethylene. (Research purpose) The research purpose is determining the power indicatorsof the working parts of tillage machines using a polymer coating on their surface. (Materials and methods) Experiments were carried out on laboratory measuring equipment to study the working parts of the modernized working part of the tillage machine, equipped with a coating of ultra-high molecular weight polyethylene with varying speed and depth of tillage. The relative humidity of the soil during the study remained in the range of 62-63 percent. The fastening of the polymer material was carried out mechanically. (Results and discussion) It was found that the values of the traction resistance of the working part coated with ultra-high molecular weight polyethylene are lower by 13 and 16 percent at speeds of 1.39 and 1.94 meters per second, respectively. A significant decrease in soil adhesion to the polymer coating was observed in comparison with the metal surface. (Conclusions) The results of the study showed that the traction resistance of the soil, as well as adhesive, in contact with the coating of ultra-high molecular weight polyethylene is lower than that of steel. The highest percentage of change in traction force was observed at a speed of 1.94 meters per second and a processing depth of 0.26 meters. Further research in this field can significantly increase the effectiveness of the use of ultra-high molecular weight polyethylene coating in reducing traction resistance and reduce the energy consumption of the tillage process.

Abstract:

Carbon nanotubes (CNT) have been shown to enhance the engineering properties of plastic fibers in ballistic-resistant garments enabling the garments to withstand very high impact forces while remaining to be lightweight. Previous study shows that by reinforcing ultra high molecular weight polyethylene (UHMWPE) fibers with a small amount of carbon nanotubes, the fibers are simultaneously toughened and strengthened. In this paper, we study the mechanical properties of carbon nanotube reinforced ultra high molecular weight polyethylene (UHMWPE) by using micromechanics-based Mori-Tanaka model. Results show that the addition of small amount of carbon nanotubes as reinforcement can substantially improve the mechanical properties of the UHMWPE fibers.
