Abstract
An engineered plank material and a method for making the plank material are disclosed. The plank material includes a veneer that is made out of plant material, and includes a nonwoven fabric or fiberglass mesh adhered to an inward-facing portion of the veneer. The plank material includes an adhesive paper material including macromolecular glue, which is between the veneer and a third layer of the plank material, which is constructed from one of bamboo, wood, or paper. The plank material then includes a fourth layer which is an adhesive paper material including a micromolecular glue. These layers are compressed together at a high heat and a high pressure in order to form the plank material.

A compressed layered plank material constructed with a plurality of layers, the plank material comprising:
- a first layer of the plurality of layers, the first layer constructed from plant material and including one of a nonwoven fabric and a fiberglass mesh adhered to an inward-facing portion of the plant material in order to increase an impact resistance of the plank material;
- a second layer of the plurality of layers, the second layer constructed from an adhesive paper material including a macromolecular glue;
- a third layer of the plurality of layers, the third layer constructed from one of bamboo, wood, or paper;
- and
- a fourth layer of the plurality of layers, the fourth layer constructed from an adhesive paper material including a micromolecular glue, wherein at least two of the plurality of layers are compressed together at a temperature of greater than 100° C. and a pressure of greater than 505 kPa, wherein
- the macromolecular glue comprises 50-55% melamine, 35-40% plasticizer, and 3-5% formaldehyde, and the micromolecular glue comprises 70-82% melamine, 5-12% plasticizer, and 3-6% formaldehyde.
