A Review of Dynamic Mechanical Characterization of High Temperature PMR Polyimides and Composites 880152
This paper reviews the applications of dynamic mechanical characterization for high temperature PMR polyimides and their graphite fiber reinforced composites. This characterization technique provides insights into the processability, performance and structure property relationships of the polyimides and composites. The dynamic mechanical properties of various molding powders, commercially obtained prepregs, neat resins and as-fabricated as well as aged composites are presented. Some applied aspects of the dynamic mechanical data are discussed.
