Embodiment Construction

[0022] In one aspect, disclosed herein are compositions comprising one or more polymers and a reclaimed composite material, such as particles formed from a reclaimed (or recycled) composite material. The compositions of the present disclosure have certain advantageous properties compared to the individual components combined to form the compositions, for example, superior moisture and fire resistance.

[0023] In some embodiments, the composition includes a recycled composite material including glass fibers or carbon fibers. For example, in certain embodiments, the composite material is glass fiber reinforced or carbon fiber reinforced. Any suitable composite material may be included in the compositions disclosed herein. Any pre-existing composite product or raw material that is wasted, surplus, or damaged beyond use can be included in the compositions disclosed herein. Non-limiting examples of such material sources include cured or uncured scrap and rovings from manufacture...

Abstract

Compositions prepared from recycled composite materials are disclosed. The compositions can be used to produce new, recyclable solid composite products, including building materials with improved strength and moisture resistance.

Description

technical field [0001] This application claims the benefit of Provisional Application No. 62 / 714,460, filed August 3, 2018, the entire contents of which are expressly incorporated herein by reference. technical field [0002] The present disclosure relates to compositions and novel products comprising polymers and recycled composite materials such as glass fibers and other glass fiber and carbon fiber reinforcements, and methods of making the compositions. Background technique [0003] Wind energy, and more specifically the use of wind turbines to generate electricity, is a booming market. There are many companies producing blades for this growing number of turbines which need to be replaced regularly if they become worn or damaged. This creates problems for blade manufacturers, utilities, and other entities that may not wish to send decommissioned blades to landfills. While the prospect of recycling wind turbine blades may be attractive and consistent with the concept o...
