Abstract

A process for fiberglass recovered from recycling of windmill or similar products at the end of lifecycle converted into a non-woven fiberglass mat and applying predetermined sizing. Sizing is applied to this fiberglass mat by spraying silane sizing on both sides of the mat. Recycled fiberglass content can be operably varied. Polyurethane resin can be sprayed onto either the recycled non-woven fiberglass mat alone or on a combination of recycled fiberglass mat and virgin fiberglass mat. This resin-impregnated mat is then placed onto a heated tool in a compression molding machine. Exemplary application of the recycled glass fiber mat is in electric vehicle composite battery cover and plug-in hybrid electric vehicle composite battery cover.
