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.

Reinforced Plastic

Carbon fiber reinforced plastic (CFRP) is a composite material in which carbon fibers are impregnated with resin to achieve both high strength and high rigidity. CFRP is an excellent material, but it is expensive in terms of materials, manufacturing costs, and capital investment, and it takes a lot of time to complete a product. In order to solve these problems, the demand for de-autoclaving has been increasing in recent years. If molding can be performed without autoclaving, it will be possible to reduce costs and improve productivity in terms of materials and capital investment costs.

Abstract The ultra-high-molecular-weight polyethylene reactor powders are widely used for the actively developing solvent-free method for producing high-strength high-modulus PE filaments, which includes the compaction and sintering of a powder followed by orientational hardening. To find an appropriate regime of the technological process, it is important to know how the nanostructure changes when transforming from a powder to a precursor for hardening. Nanocrystalline lamellae are characteristics of the powder structure. For the first time, the DSC technique was used to follow changes in the thickness distribution of lamellae in ultra-high-molecular-weight polyethylene reactor powder on its way to a precursor for orientation hardening. It was found that the percentage of thick (>15 nm) and thin (10 nm) lamellae in compacted samples and those sintered at temperatures lower than the melting temperature of PE (140°C) remains nearly the same. However, significant changes in the content of lamellae of different thicknesses were observed in the samples sintered at 145°C with subsequent cooling under different conditions. The influence of the lamellae thickness distribution in precursors on the mechanical characteristics of oriented filaments was discussed.

In this study two types of PAN-based continuous carbon fibers were compared: high-modulus UMT-430 and high-strength UMT-49. The dynamics of carbon fibers oxidation at a temperature of 600°C with an exposure from 1 to 6 hours was evaluated. It was found that high-strength fibers burn out faster than high-modulus. The surface of the fibers in the initial state and after annealing was investigated. Composite samples with an Al-6Mg alloy matrix, reinforced with these types of carbon fibers, were tested for three-point bending. It was found that the strength of the composite with high-modulus fiber was more than 2 times higher than strength of the composite with high-strength fiber. The samples fracture surfaces of Cf/Al composites after mechanical tests are investigated.

This article considers scientific and practical principles of concrete surfacing. As it was found, such production can be done by impregnating the surface of high-strength concrete with silica sol, measuring the surface energy of nanoparticles introduced. A technique was introduced for calculating surface energy of sols, so was the range of energy necessary to create concrete with a shock resistant surface, determined by measurement and calculation. The content contains possible reactions resulting in new phases in the concrete top during the impregnation with silica sol. Physical and mechanical characteristics of surfaced concrete were also outlined ad considered, so were the XRD data and electron microscopy data. Various types of energy used to surface concrete until high dynamic strength were compared. This article provides evidence that surface energy of sol nanoparticles can be considered as an independent alternative source.

This work presents a method of strengthening concrete structures based on textiles of high strength and mortars. The combination of textiles and mortars produces a new composite material with cementitious matrix. This material can be used for the reinforcement of concrete beams under bending loads. We tested several combinations of fibers: glass, Poliparafenil Benzobisoxazol (PBO), steel and carbon fibers with mortar and we used them to reinforce precast concrete beams. All the specimens were tested with a four-point load test. We discuss the performance of the specimens and we compare the ultimate results with the formulae from FRP codes.
