Characterization of Engineering Polymers by Dynamic Mechanical Analysis
1989
Abstract There is a growing need for the use of polymers in high-strength and engineering applications, and many new materials and composites have been developed to satisfy this need. Traditionally, thermosetting polymers have been employed as high-strength materials, with the incorporation of various fillers or additives to improve shortcomings in strength and temperature performance. Although these materials are largely unrivaled in high-temperature performance, some of the newer engineering thermoplastics, such as poly(ether ether ketone)(PEEK), poly(ether sulfone) (PES), poly(pheny1ene sulfide) (PPS), and the new backbone liquid-crystal polymers are becoming much more widely used. With this widespread use and with the increasing complexity of polymer blends and composites, there is a strong requirement for a universal means of characterizing such materials in terms of mechanical properties and high-temperature performance. A powerful and versatile analytical technique which is capable of application t...
