Abstract
A method of making a recycled fibre reinforced resin containing product comprising a quantity of fibre reinforced resin pieces mixed together with a quantity of granular aggregate material, and a binder, in which the fibre reinforced resin pieces and the granular aggregate are intermixed with and embedded in the binder, the binder being selected from materials having an initially plastic state, fibre reinforced resin pieces and the granular aggregate being intermixed, with the binder material being thereafter added and the binder materials being thereafter hardened at room temperature into a hard mass without the application of heat, and apparatus for carrying out the method.
Claims21
A method of manufacturing a recycled fibre reinforced resin containing product and comprising the steps of;
- shredding fibre reinforced resin materials into a plurality of fibre reinforced resin pieces of between 2 and 8 inches in length and breadth, and having a thickness substantially equal to no more than about the thickness of said fibre reinforced resin material;
- forming an aggregate granular material with a granule size of between about 1/8 of an inch and 1/2 of an inch,;
- mixing said aggregate granules with said fibre reinforced resin pieces in a dry state without heating wherein the proportions of said aggregate granules, by volume in said dry mix is greater than that of said fibre reinforced resin pieces in a dry mix;
- formulating a room temperature binder in a plastic state, and;
- mixing said binder while in its plastic state with said dry mix of said fibre reinforced resin pieces and said aggregate granules without heating, and permitting the same to harden.
Apparatus for manufacturing a recycled fibre reinforced resin containing product and comprising;
- shredder means operable to shred fibre reinforced resin material into a random sized fibre reinforced resin flakes into pieces of between 2 inches and 8 inches in length and breadth;
- grinder means operable to grind some of said fibre reinforced material into granules of between 1/8 and 1/2 inch in size.
- aggregate supply means for supplying granular aggregate material;
- dry mixer means for receiving fibre reinforced resin material and said aggregate granules and intermixing the same in the dry state;
- binder supply means for supplying a room temperature binder in a plastic state without heating;
- binder mixer means for receiving said dry mix of fibre reinforced resin material and said aggregate granules, and said binder in a plastic state, and operable to intermix the same to form a mixture in a plastic state at room temperature without heating, and,
- ejection means for ejecting said material while it is in said plastic state.
