“…While the mean elongation at break of GFRT (1.5 %) and FFRT (1.3 %) is quite similar, the CFRT features a more brittle behavior with only 0.8 % elongation at break. For the FFRT as well as CFRT fibre volume fractions (FVF) of 42 % and 34 %, respectively could be achieved and the resulting mechanical properties are in good accordance with those found in similar works [4,5]. The GFRT displays a FVF of 33 % and the resulting Young's modulus is notably lower than in comparable literature [6] where, however, a powder impregnation was applied.…”

Carbon fibers (CFs) have high service temperature, strength, and stiffness, and low weight. They are widely used as reinforcing materials in advanced polymer composites. The role of the polymer matrix in the composites is to provide bulk to the composite laminate and transfer load between the fibers. The interface between the CF and the resin matrix plays a critical role in controlling the overall properties of the composites. This paper aims to review the synthesis, properties, and applications of polymer matrices, such as thermosetting and thermoplastic resins.

“…This study focuses on an engineering polymer, with a high potential, i.e., polyamide 6. Most literature studies present polyamide 6 composites reinforced with short fibers (carbon, glass or aramid) processed by melt extrusion [9][10][11][12] , a few studies present fabric-reinforced polyamide 6 composites [13][14] , because of the technological processing difficulties arising from fabric-impregnation issues generated by the molten polymer and fiber wet out. 15 Moreover, the data concerning the optimum solution viscosity range and the optimum polymer/solvent ratio when using the solvent-impregnation method is very briefly discussed, although its importance is underlined [16][17][18] , as the rheological properties of the matrix are important for establishing the composite's processing parameters.…”

This paper presents the production of carbon-fiber-fabric-reinforced laminated composites based on a polyamide 6 matrix using a multiple-stages technique that involves polymer dissolution in formic acid followed by fabric impregnation and high-temperature pressing. The polyamide/solvent ratio's influence on the interface and mechanical properties is discussed, analyzing three PA6 weight contents of (10, 20, and 30) % in a formic acid solvent. The mechanical behavior of the obtained laminated composites is evaluated using tensile and 3-point bending tests and the fracture cross-section is analyzed using microscopy investigation techniques in order to evaluate the fiber-matrix interface and the composite fracture mechanism. The results show that the best mechanical performance is obtained when using a solution of 20 % mass fraction of polyamide in formic acid, as this leads to the formation of a uniform polymer layer that is able to completely embed the fibers that constitute the fabric and create a strong mechanical interface within the composite. Keywords: polyamide 6, carbon fiber, mechanical properties, polymer/solvent ratio, mechanical interfacê lanek predstavlja izdelavo laminatnega kompozita na osnovi poliamida 6, oja~anega s tkanino iz ogljikovih vlaken, z uporabo ve~stopenjske tehnike, ki vklju~uje raztapljanje poliamida v mravljin~ni kislini ter impregnacijo tkanine in stiskanje pri visoki temperaturi. Razlo`en je vpliv razmerja poliamid/topilo na stik in mehanske lastnosti, z analizo treh masnih vsebnosti PA6 (10, 20, 30) % v mravljin~ni kislini. Mehansko obna{anje dobljenega laminiranega kompozita je ocenjeno z nateznim preizkusom in s 3-to~kovnim upogibnim preizkusom, presek preloma pa je analiziran z mikroskopsko tehniko, da bi ocenili stik z vlaknato osnovo in mehanizem preloma kompozita. Rezultati ka`ejo, da je najbolj{a mehanska zmogljivost dose`ena pri uporabi raztopine z 20 % masnim dele`em poliamida v mravljin~ni kislini, ker to povzro~i nastanek enakomernega polimernega sloja, ki lahko popolnoma obda vlakna tkanine in ustvari mo~an mehanski stik v kompozitu. Klju~ne besede: poliamid 6, ogljikovo vlakno, mehanske lastnosti, razmerje polimer/topilo, mehanski stik
