Embodiment Construction

[0017] Embodiments herein enable the manufacture of lightweight, paintable CFRP parts with a Class A surface finish, a weight reduction of over 70% when compared to a steel roof, and an acceptable cost increase (less than the saved $5.00 per pound), offset by fuel savings achieved through lightweighting while being able to recycle CFRP at end-of-life. CFRP parts can also be made from other recycled fiber reinforced polymers (FRP) including fiber reinforced plastics.

[0018] Embodiments herein include composite resin formulations that, after curing, incorporate a high glass transition temperature epoxy resin, meaning that it has a glass transition temperature greater than 150°C. The formulation includes recycled functionalized CFRP particles having functional groups that are similar to or compatible with epoxy resins and that react with epoxy resins when cured. This creates a cross-linked structure with a network of chemically linked CFRP particles distributed within the cure...

Abstract

A method of recycling fiber reinforced polymers includes grinding used fiber reinforced polymers material to produce ground particles, functionalizing the ground particles to produce functionalized particles, dispersing the functionalized particles into a base resin, dispensing the resin with functionalized particles into one or more layers of continuous fiber mats, molding the resin with functionalized particles and the continuous fiber mats into a form of a desired part, and curing the form to produce the part. The used fiber reinforced polymer materials may be carbon fiber reinforced polymers or glass fiber reinforced polymer materials.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and benefit of U.S. Provisional Application No. 62 / 979,513, filed February 21, 2020, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to fiber reinforced polymers (FRP), and more particularly to recyclable FRP. Background technique [0004] Vehicle lightweighting involves building cars and trucks that weigh less for better fuel efficiency and handling. Many governments and automakers around the world have made it a priority. The main benefits are improved vehicle fuel economy and reduction in greenhouse gas emissions. Due to its high specific strength, stiffness, and excellent corrosion resistance, carbon fiber-reinforced polymers (CFRP) enable vehicle body panels with the highest potential weight reduction of approximately 70%, far outperforming alternative lower-risk strategies that Strategies include at least 40%...
