Abstract
Typical commercial surface treatments for continuous carbon fibers are often unavailable for discontinuous fibers. As such, there is little variety of chopped fiber surfaces leading to non-ideal coating solutions which result in poor interfacial compatibility between fibers and a composite matrix. A method of applying a highly effective coating using a high throughput technique for chopped carbon fibers. The method provides the ability to tune both the coating thickness and chemical functionality using processing parameters. The coatings are evaluated using X-ray photoelectron spectroscopy (XPS) for uniformity and composition. Using this technique, thermoplastic composites are highlighted showing an increase in interfacial shear strength (IFSS) of 25 MPa. This process shows promise for increasing the throughput of surface treatment of chopped fiber on the industrial scale.
