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.
A method of manufacturing an engineered plank material, the method comprising:
- de-sugaring and skimming fat from one or more plant material layers;
- applying a nonwoven fabric or fiberglass mesh to an inward-facing portion of a plant material veneer;
- dry balancing each of the one or more plant material layers and the plant material veneer to control a moisture content in each of the one or more plant material layers and the plant material veneer;
- permeating each of the one or more plant material layers and the plant material veneer with flame retardant under negative pressure;
- and
- compressing each of the one or more plant material layers and the plant material veneer together, placing adhesive paper between each of the one or more plant material layers and the plant material veneer, at a temperature of greater than 100° C. and a pressure of greater than 505 kPa.
