Abstract
Methods of producing particles of fiber and resin from fiber-resin composite materials are disclosed. The particles may be combined with a resin system and optionally combined with fillers, binders or reinforcements to produce new cured solid composite products.
Claims22
A recycling method of producing a composite product, comprising:
- tracking one or more composite wind turbine blades, wherein the tracking further comprises collecting and organizing information with respect to the composite wind turbine blades utilized by an energy producer;
- processing the tracked one or more composite wind turbine blades so as to form pieces having at least one dimension that is ½ inches or less of a resultant composite wind turbine blade material;
- mixing the processed resultant composite wind turbine blade material with one or more materials selected from:
- a resin, a water content, and one or more additives;
- forming the mixture of processed composite wind turbine blade material into a shape for providing a resultant composite product;
- and
- applying a pressure and a temperature to cure the formed mixture.
4 more elements
A recycling method of producing a flame retardant composite product, comprising:
- tracking a composite wind turbine blade material throughout its chain of custody;
- processing the wind turbine blade material identified in the tracking step to provide a plurality of wind turbine blade (WTB) feedstock pieces that are at least one inch or less in one or more dimensions;
- receiving the processed wind turbine blade (WTB) feedstock pieces at a processing facility (PPF);
- refining the processed wind turbine blade (WTB) feedstock to provide a plurality of composite pieces ranging from about 1/16 inches up to about ½ inches in one or more dimensions;
- spraying the plurality of composite pieces with one or more liquids to provide a flame retardant composite mixture, wherein the one or more liquids further comprises:
- a Polymeric methyl-diisocyanate (MDI) resin ranging from 3% up to about 10% in content, a water content, and one or more additives;
- forming the flame retardant composite mixture into a shape for providing a resultant flame retardant composite product;
- hot pressing the formed flame retardant composite mixture at a temperature and pressure to cure the shaped composite mixture;
- and
- cutting the cured flame retardant composite mixture to one or more dimensions in height, length and width to provide the resultant flame retardant composite product.
7 more elements
A tracking method for recycling wind turbine blade materials, comprising:
- manufacturing one or more wind turbine blades;
- authenticating at a backend of a system that further includes:
- a solutions interface, a manufacturer interface, an energy producer interface, and a database, wherein authenticating further comprises providing a unique username and password;
- initiating a new record in a form provided at the backend, wherein the new record includes initial collected information of the one or more wind turbine blades to be tracked throughout its chain of custody;
- storing the initiated new record in the data base;
- and
- editing the form and thereafter storing after editing by way of the backend, wherein the editing is provided by a user of at least one of:
- the solutions interface, the manufacturer interface, and the energy producer interface, and wherein the editing further comprises utilizing screens at the backend to provide information selected from at least one of:
- blade creation, compositions, maintenance, disposal time, and any other relevant information related to the tracked one or more wind turbine blades.
