Elastic-Plastic Poisson's Ratio Of Borsic-Reinforced Aluminium Composites, Ronald Edward Allred
Elastic-Plastic Poisson's Ratio Of Borsic-Reinforced Aluminium Composites, Ronald Edward Allred
Nuclear Engineering ETDs
Poisson's ratio as a function of tensile strain has been examined for four volume fractions of unidirectional Borsic-reinforced aluminum composites. Linear relationships were found between Poisson's ratio and fiber volume fraction during Stage I (elastic filaments-elastic matrix) and Stage II (elastic filaments-plastic matrix) deformation which confirms that rule-of-mixtures equations may be used to predict Poisson's ratios for metal-matrix composites. These equations must be used with care, however, due to differences in the Poisson's ratio behavior of the components of the composite when tested alone and in situ in the composite. These differences are attributed to the triaxial stress field generated …

The Effect Of Porosity On Transverse Tensile Strength Of Filament Wound/Cvd Carbon-Carbon Composites., Gilbert William Brassell
Nuclear Engineering ETDs
Filament wound/CVD (Chemical Vapor Deposition) carboncarbon composites have received considerable attention within the past few years due to desirable characteristics such as high heat of ablation, thermal shock resistance, strength improvement at elevated temperatures, and chemical inertness. However, poor mechanical properties in the transverse direction have hampered the total effectiveness of these composites in some applications and a study of the effects of porosity on transverse tensile strength of filament wound/CVD carbon carbon composites has been conducted.
Two types of filament wound/CVD carbon carbon composites were studied. A standard filament wound/CVD carbon composite, and a composite similar to the standard …
