Mater Des 2010 ; 31: 3810 – 3815 . with the Adams-Bacon damping criterion, are utilised for prediction of moduli and flexural damping of anisotropic CFRP (Carbon fiber reinforced polymer) and GRP beams with respect to fibre orientation. Billups E K [2] works on several two-dimensional theories for investigating the SDC (Specific damping Carbon/epoxy (c/ep) composite rotorcraft blades, consisting of carbon fibers in a matrix of epoxy, are commonly used to manufacture rotorcraft blades because of their good balance of mass, stiffness, and strength properties. To improve vibration damping performance of Carbon Fiber Reinforced Plastics (CFRPs), a damping layer is typically sandwiched between two CFRP layers. Herein, a hybrid damping layer design is proposed, to obtain an optimum structure with high performance in both stiffness and damping.

2011-08-19 · Highlights Vibration damping characteristics of nanocomposites and carbon fiber composites containing MWCNTs are studied. The damping ratio of the hybrid composites is enhanced with the addition of CNTs due to sliding at the CNT-matrix interfaces. The damping ratio is dependent on the amplitude as a result of the random orientation of CNTs in the epoxy matrix. The natural frequency shows for the analysis of carbon fiber cable damping and its effect on dynamical behavior of deployable space structure is scarce. The objective of this work is to examine the variation of cable damping involving different cable properties and the ambient environments through several carefully instrumented tests.

The damping performance of the hybrid CNT-carbon fiber-reinforced epoxy composite was examined using dynamic mechanical analysis (DMA). Mechanical testing confirmed that the degradations in the strength and stiffness as a result of the GSD process are far less than those encountered through using the CCVD technique and yet are negligible compared to the reference samples. Carbon fiber reinforced plastics (CFRP) are widely used as structural materials in applications such as spacecraft structures.

The objective of this work is to examine the variation of cable damping involving different cable properties and the ambient environments through several carefully instrumented tests. A C arbon-fiber reinforced H ybrid- M atrix Composite (CHMC) was designed to improve the material damping property in conventional carbon-fiber reinforced epoxy (CF/E) through the interfacial reaction of two reactive polymeric compounds: still-curing epoxy-based phase I with a highly crosslinked morphology and lightly crosslinked still-curing polyurea elastomeric phase II. Average damping loss factor of the carbon fiber composite parts is approximately 1%. Even though carbon fiber composite material damping loss factor is five times greater than that of steel, it is significantly less than laminated sandwich steel which has a damping loss factor of approximately 25% [ 1 ] [ 2 ].
