Methods and systems for recycling of laminated materials
Abstract:
In an embodiment of the disclosure, there is provided a method and system for recycling a cured composite laminate material into a delaminated recyclate that maintains a fiber volume fraction and a lamina level fiber alignment substantially the same as the cured composite laminate material. The method provides a cured composite laminate material having a fiber volume fraction and a lamina level fiber alignment. The cured composite laminate material undergoes solvent soak preconditioning, liquid solvent removal, pre-heating, and rapid heating with phase change delamination of the cured composite laminate material to obtain the delaminated recyclate that maintains a fiber volume fraction and a lamina level fiber alignment substantially the same as the cured composite laminate material.
