Long Discontinuous Fiber - Composites (LDF™) were developed for thermoforming. This material with 5 cm long aligned fibers in a PEKK matrix has similar static mechanical properties as continuous fiber systems. A method is described to determine the elongation created by thermoforming without post-compression based on ultrasonic evaluation. During the experiments, a correlation between the plastic deformation of the material and the generated voids in the material was found.
