Abstract

A technology for two-stage electrostatic spraying of high-molecular-weight and low-molecular-weight polyphenylene sulfide powders is presented. The influence of electrostatic charge on the wetting angle of molten particles of powdered polyphenylene sulfide binder on carbon fiber surface was determined. The compactability of the obtained prepregs was analyzed. Temperature-time parameters for consolidation and thermoforming were optimized using differential scanning calorimetry and rheometry methods. A methodology for vacuum consolidation and pressing is described, enabling the production of consolidated plates that serve as blanks for thermoforming.
