摘要: The effect of prestraining on the elastic modulus,E, and damping capacity, tanφ, 10 20 vol% Al2O3 particle-reinforced composites has been investigated as function temperature using dynamic mechanical analysis. Both modulus capacity were found to increase with volume fraction. At relatively insensitive prestrain. However, at it was observed that decreased increasing prestrain while increased significantly. These results are discussed in terms fraction broken particles, particle size, differential thermal expansion between matrix particulate.
