Physical And Mechanical Characteristics

The present study investigates the influence of carbon fibers of «Belum» brand on the performance properties of polymer composites based on ultrahigh-molecular weight polyethylene. It was established that the composite complex with the content of carbon fibers in the amount of 5 wt.% has the optimum complex of properties. The rate of mass wear is reduced by 3.3 times while maintaining the physical and mechanical characteristics at the level of the original polymer. It was established that the creep of PCM with the composition of UHMWPE + 5 wt.% Belum is 2 times less than the initial polymer. Also, the properties of the developed material based on UHMWPE were compared with unfilled and modified polytetrafluoroethylene (PTFE). It is shown that the creep of UHMWPE is less than the creep of PTFE by 12.5 times. The creep of the composite based on UHMWPE is less than the creep of the composite based on PTFE 13 times.

Ultrahigh Molecular Weight

Low-density polyethylene single-polymer composites (SPCs) reinforced with sandwiched ultrahigh-molecular-weight polyethylene woven fabric were prepared by insert injection molding. The process combines aesthetic and processing advantages. A processing temperature window (135–155°C) of a very short cycle time (less than 30 s) could be realized. The mechanical properties and morphologies of the samples were evaluated. The results suggested that the polyethylene SPCs were prepared successfully with concurrent increases in flexural strength (∼57%), tensile strength (∼164%), and impact strength (∼69%). The effects of different processing parameters including the nozzle temperature, injection pressure, injection speed, and the holding time were discussed. Numerical simulation results were used in the analysis.

Properties Of Composites

The present study investigates the influence of carbon fibers of LO-1-12N/40 brand and modified carbon fibers of "Belum" brand on performance properties and structure of polymer composite materials based on UHMWPE of Gur-4150 grade. It has been established that introduction of both modified carbon fibers and LO-1-12N/40 carbon fiber in an amount of from 1 to 10 wt.% into the polymer matrix does not lead to significant changes in stress-strain properties of composites compared to the starting polymer. It is shown that the wear resistance of the obtained materials is significantly increased when filling with 5 wt.% carbon fibers of "Belum" brand. The rate of mass wear of polymer composite materials is reduced by 3.3 times; the friction coefficient of PCM is lowered by 3.5 times relative to the starting polymer.
