New fabrication techniques have been developed for uniaxial creep specimens of pitch-based carbon filaments, with a matrix-free, test section. Pitch-based carbon filaments were found to plastically deform up to 73% elongation without necking. Mechani

The internal microstructure of new high modulus, pitch-based, post-creep carbon filaments is compared to that as-received and is similarly compared to post-creep and as-received PAN-based filaments. The structure of the carbon filaments is studied us

An isotropic, pyrolytic carbon is the favored material for mechanical heart valve components. The question has been raised on the size of the threshold crack length for cyclic fatigue crack propagation. Preliminary results are presented that indicate

The test method introduced here enables the fatigue test of a brittle material at a stress level that is as high as its ultimate fracture strength. The procedural design of the test eliminates uncertainties that often make interpretation of the resul

A chemical vapor deposited, silicon alloyed, isotropic pyrolytic carbon (PyC) has been widely regarded as the primary candidate for the structural material for components of mechanical heart valve prostheses. The biocompatibility of PyC, in particula

In this work, the fracture toughness of monolithic pyrolytic carbon and sandwich composites of this carbon on a graphite substrate were measured by a disk-shaped compact specimen and by using a tensile specimen. On this material, a large number of sp

Studies on the biaxial compressive strength of alumina showed that the compressive failure was insensitive to the presence of the secondary compressive stress except possibly close to the equi-biaxial compressive state. It was found in another study

A recent find in the Idaean Cave in Crete of two rock crystal lenses of unusually good optical quality led to this investigation of other lenses from antiquity. The evidence indicates that the use of lenses was widespread throughout the Middle East a
