Ceramic/Polymeric Hybrids with Reduced Coefficients of Thermal Expansion

Abstract:

Article Preview

The mismatch of the coefficient of the thermal expansion (CTE) is one of the main causes of crack initiation and delamination for carbon fiber-reinforced polymer hybrids and metal/polymer hybrid materials. In this research, a negative CTE ceramic material (zirconium tungstate) was incorporated with a thermoset polymer (bismaleimide) resulting in a ~40% reduction in CTE and a significant improvement in thermal stability. The morphology showed good dispersion of the zirconium tungstate particles within the bismaleimide. Comparisons of the experimental CTE values with the rule-of-mixture and the analytical micromechanical models will be discussed.
