A study of the mechanical behavior of a 2-D carbon-carbon composite
… characterize the out-of-plane fracture of a 2-D carbon-carbon composite and to gain an understanding of the factors influencing the stress distribution in such a laminate. The experimental portion of this study consisted of performing an out-of-plane tensile test in a scanning electron microscope …

ADVANCED PHOSPHORUS BASED MIGRATION RESISTANT ANTI-OXIDANTS FOR CARBON-CARBON COMPOSITE AIRCRAFT BRAKES WITH INCREASED CATALYTIC OXIDATION RESISTANCE
Carbon-carbon composite brakes are one third the weight of typical steel brakes, and they attain strength and frictional properties at temperatures up to 1600°C. C/C composite brakes can endure high temperatures, but in the presence of oxygen they will begin to oxidize at 400°C. Anti-oxidant …

The mechanical properties of tightly woven carbon-carbon composites
<p>The mechanical properties of a tightly woven carbon- carbon composite were investigated. The flexural strength and fracture toughness of these composites were measured as a function of temperature and atmosphere. The average flexural strengths are 147.1 ± 6.4 MPa in air and 144.0 ± 5.9 MPa in …
