Quality control for the recycling of carbon fibre

Due to the inevitable variability of the end-of-life input material, the resulting recycled fibre and nonwoven or woven material will have a higher degree of variability than virgin material. To make sure such recycled fabric is usable for high-quality applications, additional methods for quality control are required.

Fresh prepreg multilayer scrap reuse

To address waste generated during production, a processing route for uncurde material is developed in MC4. Multilayer fresh prepreg scrap is processed to obtain new intermediate products that can be used to manufacture new parts.
