Disclosed is a mass plywood panel assembly including at least two engineered wood panel assemblies. Each wood panel assembly includes a first layer including a first set of billets, a second layer including a second set of billets and a third layer including a third set of billets of sheets. The first set of billets, the second set of billets, and the third set of billets are all oriented longitudinally along the length of the wood panel assembly and the at least two engineered wood panel assemblies are connected by an end joint, thereby forming the mass plywood panel assembly. Methods of manufacturing mass plywood panel assemblies are also disclosed.

Disclosed is a method for preparing an environmentally-friendly high-strength wood composite material, which includes the following steps: S1. pulverizing wood into a wood flour, adding the wood flour to an acid solution to obtain a first mixture, ball milling the first mixture to obtain a ball milled mixture, and filtering the ball milled mixture, to obtain a dually-treated wood flour; S2. adding the dually-treated wood flour to a first alkaline solution, and performing a neutralization reaction, to obtain a second mixture; S3. adding an alkaline solution to the second mixture to remove part of lignin, to obtain a lignin-partially removed wood flour; S4. washing the lignin-partially removed wood flour with anhydrous ethanol and drying, to obtain a dried lignin-partially removed wood flour; S5. subjecting the dried lignin-partially removed wood flour to hot pressing, followed by cooling, to obtain the environmentally-friendly high-strength wood composite material.
