Composite Fabrication with Graphite-Reinforced Polysulfone Prepreg Tape.

Abstract

Graphite-reinforced polysulfone composites were fabricated from three inch wide Hercules 3004-AS prepreg tape. Mechanical properties of these composites were evaluated at R. T., 250F, and 300F. Humid aging tests performed at 120F and 95% R.H. show polysulfone/AS composite properties equal to, or superior than, epoxy/AS composites at test temperatures up to 250F. Processing studies indicated that quality laminates can be prepared at pressures as low as 100-200 psi. Finally, unnotched charpy testing revealed that polysulfone/AS composites possess higher damage threshold levels due to a better fiber-to-matrix bond than do epoxy/AS composites. This strength makes polysulfone composites very desirable in aircraft component applications where the risk of foreign object damage is high.
