“…The loading rate was 2.14 MPa/s. The impact tests were carried out with a spring-controlled impact machine which has been described in detail earlier [12]. The tests were performed according to a three-point bending scheme with an impactor speed of 4.0 m/s (impact energy 13.0 J).…”

“…PSU is frequently used as a modifier for the epoxy matrix for CF reinforced composites [34][35][36]. In the 1990s, CF reinforced PSU was widely considered to be promising in medicine for arthoplastic applications, where composites filled with short [37] or unidirectional [38][39][40] CFs were mainly used in these investigations. In recent years, only few papers related to PSU based CF reinforced composites have appeared.…”

Carbon fabrics are widely used in polymer based composites. Nowadays, most of the advanced high-performance composites are based on thermosetting polymer matrices such as epoxy resin. Thermoplastics have received high attention as polymer matrices due to their low curing duration, high chemical resistance, high recyclability, and mass production capability in comparison with thermosetting polymers. In this paper, we suggest thermoplastic based composite materials reinforced with carbon fibers. Composites based on polysulfone reinforced with carbon fabrics using polymer solvent impregnation were studied. It is well known that despite the excellent mechanical properties, carbon fibers possess poor wettability and adhesion to polymers because of the fiber surface chemical inertness and smoothness. Therefore, to improve the fiber–matrix interfacial interaction, the surface modification of the carbon fibers by thermal oxidation was used. It was shown that the surface modification resulted in a noticeable change in the functional composition of the carbon fibers’ surface and increased the mechanical properties of the polysulfone based composites. Significant increase in composites mechanical properties and thermal stability as a result of carbon fiber surface modification was observed.

“…Quasi static tests were per formed using a universal testing machine of the Instron type at a low rate impact (at impact rates higher than 1 m/s but lower than 30 m/s [24,25]). This impact machine was a spring impact testing machine [26]. Both measuring complexes involved computer reading and processing of the results; in both com plexes, the same measuring apparatus was used.…”

Organic Fiber Reinforced Plastics (OFRP) based on aramid fibers are as a rule used in construc tions working under extremal conditions. In view of this, the possibility of increasing the resistance of OFRP to destruction by modifying matrices with thermoplastic polymers and carbon nanotubes (CNTs) offers much promise. In this work, we present the results obtained in a study of the properties of OFRP based on Rusar fibers and epoxy matrices containing either CNTs or a thermoplastic (PSK 1 polysulfone) or both these com ponents simultaneously. The data obtained substantiate the possibility of using epoxypolysulfone matrices for the preparation of wound composites. This modification noticeably increases crack and impact resistance of OFRP based on aramid fibers without decreasing the glass transition temperature, as when matrices are plas ticized by rubber and active diluents. The strongest effect of polysulfone introduced into an epoxy matrix is observed at a large (20 wt %) content of PSK 1. The modification of epoxypolysulfone matrices by CNTs also increases the shear strength of OFRP and almost does not change the fracture toughness and compression strength. The introduction of CNTs into epoxy matrices is less effective and can increase crack growth resis tance of OFRP by approximately 30% only at a large (1%) content of CNTs. Small CNT admixtures (0.3-0.6%) do not influence the fracture toughness. Possible mechanisms of the changes observed are considered. Fig. 4. Dependence of the fracture toughness G IR of OFRP based on a modified epoxy matrix on the amount of polysulfone PSK 1 or CNTs introduced into the matrix: (1) PSK 1 and (2) CNT.
