“…In contrast, surface coating with carbon nanofibers (CNF) could be relatively cheap and scalable [7,9]. The approach was reported to result in the increasing yield strength of various epoxy composites in the range of 20 % to 50 % [4]. The present study aims at investigating the effect of fiber surface nanostructuring via CNF on the strength of polyethylene-based composites, which are widely used in Russia.…”

“…Among different types of additives, carbon and basalt fibers are the most popular. These fibers,being added to polymers, provide all the listed advantages at appropriate price and with a low weight of resulting composites [2][3][4]. Nevertheless, their potential is not fully discovered because of weak interaction between the fiber surface and the polymer matrix [5].…”

Abstract. Polymer composites are manufactured using pristine and surface modified fibers. Modification with carbon nanofibers (CNF),referred to as surface nanostructuring,isperformed by CCVDof ethylene on a nickel catalyst.The resultingmicrofibers have the surface area at least 2 times as high as initially. Fiber-reinforced composites have beentested for mechanical properties.Compared to the set with pristine fibers, the composites containing the modified carbon fibers show an increase in the yield strength in the range of 20 % to 25 %. The reinforcement mechanism is also investigated, with emphasis laid on the fiber/matrix interface.

“…In this context, the mechanical properties of high performance composites are dependent on several important microstructural properties [9,10]. It is well known that in carbon material reinforced polymer composites, local interactions between the fibre surface and the matrix at the vicinity of this fibre, can be transferred over longer distances thanks to the creation of an interphase area.…”

This work addresses the challenging fibre-matrix compatibilization and interface adhesion improvement of poly(etheretherketone) (PEEK) composites reinforced with pitch-based carbon fibre. An innovative and environmentally friendly method, inspired both by supramolecular "layer-by-layer" (LBL) assembly and by the composition of adhesive proteins in mussels was designed to modify the carbon fibre surface and improve the composites transverse properties by supramolecular interactions. The results proved that few sensitive carbon surfaces can be selectively modified by stable polyelectrolyte complexes and catechol amine polymer partners dispersed in water in such a way that a sizing treatment can be applied by techniques as simple as immersion or spraying procedure. It was shown that the combination of these solutions self-organized to form thin deposits containing compatibilization and/or crystallization promoter partners, thought transcrystallinity, onto carbon surface. This approach is an innovative and environmentally-friendly method which improves fibre-matrix interface quality in terms of compatibilization, adhesion and mechanical properties.

“…However, the essential mechanical characteristics of these composites such as toughness, longitudinal and transverse strength limited by the intrinsically poor interfacial adhesion between polymer materials and reinforcing CF surface. It is a long existing critical issue needed to be solving for ensuring the continued development of CF reinforced polymer composites for potential advanced composites applications [4][5][6][7][8][9].…”

Abstract.In the present investigation, we prepared two types of CF composites. The first prepared composite sample was CF/epoxy resin composite and the second was CF/epoxy resin / with a different weight ratio of magnetic iron oxide. Magnetic iron oxide was prepared by coprecipitation method, with particle sizes measured in range 25:35 nm. The resistance to penetration of high kinetic energy projectile of the prepared composite sample was measured and It was found that addition of 5% nano-particles of magnetic iron oxide to composite material sample decrease the residual velocity of projectile penetrating it by 9%.i.e increasing resistance of the sample to penetration of high kinetic energy projectile.it was found that the Resistance to penetration of sheet of composite material sampleC4 of weight=40.32kg to projectile 7.62×39 mm AP at distance 15m equivalent to resistance of steel sheet of weight =54.6 kg at distance 200m.Resistance to penetration of sheet of composite material sampleC4 to projectile 7.62×39 mm AP at distance 10m equivalent to the resistance of high-quality steel sheet(steel4340) of weight=47.85 kg at distance 25m.
