Mechanical and morphological characterizations of carbon fiber fabric reinforced epoxy composites used in aeronautical field

Abstract

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 (8552 and F584) 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 (0°/90°) 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.

Study on thermal stability of typical carbon fiber epoxy composites after airworthiness fire protection test

“…[1][2][3] In recent years, the study of the carbon fiber epoxy composites mainly focused on the mechanical properties and the effect of environmental, laser, and other factors on the aging of materials and ablative performance. But the elastic modulus and strength of aluminum alloy decrease to zero at 400 C. In contrast, the strength and elastic modulus of the carbon fiber composite material are basically unchanged at 400 C. Therefore, carbon fiber composites not only have the benefit of weight reduction but also have good heat resistance, which has been widely used in the aviation field, especially in the field of civil aviation.…”

“…The composite material has thus a significant role in promoting for the future aircraft development toward to large-scale, heavy load and high-speed inthe case of the aircraft safety. [1][2][3] In recent years, the study of the carbon fiber epoxy composites mainly focused on the mechanical properties and the effect of environmental, laser, and other factors on the aging of materials and ablative performance. The effects of carbon nanotubes (CNTs) addition on erosion and corrode of epoxy resin and carbon fiber reinforced laminate (CFRP) were investigated by Papadopoulos et al 4 They found that CFRP decreased 50% erosion rate at high impact angle (90 ) and the fracture and separation of CFRP fibers reduced due to the presence of CNT.…”

Enhancement the Armor Shielding Properties of CF/epoxy Composite by Addition Nanoparticles of Magnetic Iron Oxide

“…CF reinforced polymer composites used for aerospace efficacies, wind turbines applications in automotive energy systems, fuel cells, offshore-deep sea drilling platforms, compressed gas storage, turbo machinery and transportation, antistatic and electromagnetic shielding materials [1][2][3]. Liu and Kumar have studied the existing progress of carbon fiber structure, fabrication and properties including the introducing of nano-tubes in precursor fiber to improve the mechanical properties [4][5][6]. 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.…”

“…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.
