The main objective of this study was to investigate contribution of the non-functionalized multi-walled carbon nanotubes on the vibration damping behavior of first neat epoxy resin and then unidirectional and bidirectional continuous carbon fiber reinforced epoxy matrix composites. Epoxy/carbon nanotubes nanocomposites were produced by ultrasonic solution mixing method, while the continuous carbon fiber reinforced composite laminates were obtained via resin-infusion technique. Vibration analysis data of the specimens were evaluated by half-power bandwidth method; and the mechanical properties of the specimens were determined with three-point bending flexural tests, including morphological analyses under scanning electron microscopy. It was generally concluded that when even only 0.1 wt% carbon nanotubes were incorporated into neat epoxy resin, they have contributed not only to the mechanical properties (flexural strength and modulus), but also to the vibration behavior (damping ratio) of the epoxy. When 0.1 or 0.5 wt% carbon nanotubes were incorporated into continuous carbon fiber reinforced epoxy matrix composites, although they have no additional contribution to the mechanical properties, their contribution in terms of damping ratio of the composites were significant.

The interface between the reinforcement and the matrix is significant to metal matrix composites. The effect of aluminum (Al) content on interfacial microstructure and mechanical properties of TiO2coated carbon fiber reinforced magnesium matrix composites by squeeze casting technique have been studied (C/Mg). Mg-2wt%Al and AZ91D were used as alloy matrix. The obtained results indicate that the carbon fibers in both kinds of composites are well protected by TiO2coating, without any interfacial brittle carbide phase observed. The flexural strength of Cf-TiO2/AZ91D (1009MPa) composites is 26.5% lower than that of Cf-TiO2/Mg-2Al (1277MPa) composites. The lath-shaped precipitates of Mg17Al12in AZ91D composites lead to the mechanical properties decrease.

Abstract: Copper coated short carbon fiber reinforced aluminum alloy matrix composites have been prepared with 0.3-1.5 wt% Mg as alloying addition by stir casting. Effect of Mg on the microstructure and mechanical properties of the composites was investigated. The microstructure was observed by scanning electron microscopy and the results show that adding Mg can make the distribution of carbon fibers uniform in the composites, reduce laminated and agglomerated. Tensile test and hardness test were carried out, the results show that the tensile strength and the hardness of the composite is increased by 13% and 8% when Mg content is 0.9 wt%.
