Measurement of elastic moduli of porous SiC/SiC ceramic matrix composites using ultrasonics

Forced Chemical Vapor Infiltration (FCVI) method was used in fabricating the Nicalon TM!Silicon Carbide composites. Both through-thickness and In-plane (fiber fabric plane) moduli were determined using ultrasonic techniques. The through-thickness moduli were found to be much less than the inplane moduli. Both in-plane and through-thickness moduli were significantly decreased with an increased p...

On the Elastic Moduli of Unidirectional Fibre Reinforced Composites

A simple analytical technique is presented for obtaining lower bounds to the effective moduli of unidirec-tional fibre-reinforced composites with any repetitive array of fibres. The analysis depends upon a direct method involving stress-equilibrium and strain-continuity considerations, and thus it differs from the type of analysis due to Hashin and Hill (and others) involving variational method...

Measuring In-plane Elastic Moduli of Composites with Arrays

Ultrasonic measurements of elastic moduli of composite materials have traditionally been made on either small specimens cut from a iar ger component or by using a scanning technique with the specimen immersed in a water bath. A phase-insensitive array has been developed for rapid nondestructive measurement of in-plane elastic moduli. The array characteristics allow for determinat ion of energy ...

Molecular Dynamics Simulations of the Elastic Moduli of Polymer-Carbon Nanotube Composites

The elastic moduli of polymer-carbon nanotube composites are examined by molecular dynamics simulations of a single-walled carbon nanotube embedded in polyethylene. The overall system is modeled with a many-body bond order potential due to Brenner. Alternatively, only the carbon nanotube is modeled with Brenner’s potential and the polyethylene matrix is modeled by a united-atom potential. For t...

Elastic Moduli of Precompressed Pyrophyllite

Chao and Ruoff [*] have shown previously that by precompressing pyrophyllite prior to its use in high-pressure applications, one obtains a material which has a uniform density and uniform mechanical properties. We have recently studied the propagation of u trasonir nplIse~ in pyrnphyllit.p specimens to investigate the effect of specimen precompression on the.measured elastic moduli. Measurement...
