Acetylene Terminated Resin Mechanical Characterization

Abstract

The physio-chemical and mechanical behavior of acetylene terminated polysulfone (ATS) were determined as a function of cure states. Given one pound of the resin cure kinetics, cure rheology and dynamic mechanical properties of the neat resin were measured. The following properties were also measured as function of cure states as determined by residual exothermic or spectroscopic methods: thermophysical properties (glass transition temperatures, dilatation and free volume, surface energetics and moisture absorption/desorption kinetics) ; fracture energies; tensile properties; accelerated aging and computer-aided modelling. Prepregs of ATS were made with Celion 12K graphite fibers. Unidirectional and cross-ply laminates were fabricated and their mechanical properties were measured. To improve the processibility and fracture properties of ATS, the resin was blended with HR600P and difunctional acetylene terminated phenylene oxide (ATP). Various blending ratios were investigated, and the thermophysical, rheological, dynamic mechanical and fracture properties of the blends were measured. The blends were found to improve the fracture properties of ATS without sacrificing the high temperature properties of ATS.
