Carbon fiber reinforced composites (CFRC) have been used in aeronautical industry in the manufacture of different aircraft components that must attend tight mechanical requirements. This paper shows a study involving mechanical (flexural, shear, tensile and compressive tests) and morphological characterizations of four different laminates based on 2 epoxy resin systems (8552TM and F584TM) and 2 carbon fiber fabric reinforcements (Plain Weave (PW) and Eight Harness Satin (8HS)). All laminates were obtained by handing lay-up of prepregs plies (0o/90o) and consolidation in an autoclave following an appropriate curing cycle with vacuum and pressure. The results show that the F584-epoxy matrix laminates present better mechanical properties in the tensile and compressive tests than 8552 composites. It is also observed that PW laminates for both matrices show better flexural and interlaminar shear properties.

Carbon fabric/epoxy composites are materials used in aeronautical industry to manufacture several components as flaps, aileron, landing-gear doors and others. To evaluate these materials become important to know their mechanical properties, for example, the tensile strength. Tensile tests are usually performed in aeronautical industry to determinate tensile property data for material specifications, quality assurance and structural analysis. For this work, it was manufactured four different lami...

Four families of carbon fiber reinforced composites (CFRC) used in aeronautical industry were evaluated by flexural and interlaminar shear tests. It is also characterized three families of non-conditioned and conditioned CFRC by compression test. The composites were obtained by hand lay-up process in autoclave by using prepregs based on epoxy matrices (F155 and F584) and carbon fiber fabric reinforcements (PW-"Plain Weave" and 8HS-"Eight Harness Satin"). The F155-epoxy matrix was cured at 121 °C...

The continuous use of structural polymer composites in the aeronautical industry has required the development of repairing techniques of damages found in different types of laminates. The most usually adopted procedure to investigate the composite laminate repairing has been by repairing simulated damages in laminated composite specimens. This work shows the structural repair technique, scarf type, of a typical carbon/epoxy laminate used in the aeronautical industry, using carbon/epoxy fabric. T...

The objective of this work is to analyze the mechanism of interaction between AS4 carbon fiber and a phenolic epoxy matrix in composites cured by electron beam and to improve the interlaminar shear strength (ILSS) of the composites by modifying the carbon fiber. Some promising results have been achieved by electrochemical treatment of the carbon fibers and subsequent coating with an electron-beam-compatible coupling agent. The ILSS of an electron-beam-cured composite was improved from 72.1 to 81...

Abstract The phenomenal growth in the developments of micro/mini Unmanned Aerial Vehicles needs thin composite materials for its structural applications for weight reduction. As these structures experience high energy loading during their life cycle, the performance improvement of overall failure strain and toughness is deemed compulsory. This study investigates the application of woven aramid fabric with thin woven CFRP in enhancing the strain to failure behaviour. In this study, the in-plane t...

Co-extrusion technique is used to combine carbon fiber tows and thermoplastic polyurethane (TPU) blends into composite carbon fibers (CCFs). The TPU blends serve as the shell and the carbon fiber tows serve as the core. CCFs are fabricated into woven composites and knitted composites with electromagnetic interference shielding effectiveness (EMI SE). The effects of the content of carbon fiber tows on different fabrics are examined. The failure mechanism of CCFs is improved as the fiber slippage ...

Epoxy resins, due to their high stiffness, ease of processing, good heat, and chemical resistance obtained from cross-linked structures, have found applications in electronics, adhesives coatings, industrial tooling, and aeronautic and automotive industries. These resins are inherently brittle, which has limited their further application. The emphasis of this study is to improve the properties of the epoxy resin with a low-concentration (up to 0.4% by weight) addition of Multi-Walled Carbon Nano...

Abstract In an effort to enhance the seismic capacity of non-seismically designed reinforced concrete (RC) columns, this study proposes a retrofit method for non-seismically designed RC columns using hybrid FRP (HFRP) sheets consisting of glass and carbon FRPs. HFRP sheets can be installed for retrofitting the RC columns in a structure employing electric equipment such as metro stations or tunnels. With the assumption that the cyclic behavior of RC columns retrofitted with wrapping HFRP sheets i...
