The development of an alternative thermoplastic powder prepregging techniqueDiscussed is a novel powder prepregging technique that is based on the deposition of the powder onto fibers that have been moistened using an ultrasonic humidifier. The moisture acts as an initial binding agent for the powder until the powder can be melted onto the fiber in a subsequent heating step. LaRC-TPI powder, produced by Mitsui Toastsu, and Hercules AS-4 fiber served as the process development material system. The influence of powder particle size on this process, and the quality of the resulting composite are discussed.
