Benefits of technology

[0006] The present invention relates to a novel wood composite material suitable for use as container flooring. Rather than using tropical hardwood species, the present invention utilizes fast growing bamboo species, as well as fast-growing low-density wood species such as poplar or aspen.

Problems solved by technology

Ocean shipping in this manner saves the tedious, expensive, and time-consuming job of unloading cargo from a truck or a railroad car, loading it into the hull of a ship and reversing the process at the ship's destination.
However, tropical high-density hardwood species such as Apitong and Keruing face increasing demand while having very long growth cycles.
As a result, tropical hardwood forests are rapidly diminishing.

Embodiment Construction

[0013] When describing the present invention, all terms not defined herein have their common art-recognized meanings. As used herein, the term “about” refers to a margin of plus or minus 10%, or within the tolerance of a suitable measuring device or instrument. As used herein, “specific density” refers to density relative to water. All wood density refers to the density of oven-dried wood.

[0014] The present invention relates to a bamboo-wood composite board suitable for use as a container flooring material. In general terms, the invention comprises a multilayer board having a surface composite bamboo layer and a wood core layer. The wood core layer may be comprised of wood veneer layers or a wood strand layer, or both wood veneer and wood strand layers.

[0015] The bamboo layer comprises bamboo stripe sheets made of strips of bamboo and a suitable resin. The bamboo strips may be arranged so that the bamboo strips are all parallel, or parallel and perpendicular combination, or they m...

Abstract

A board suitable for use as container flooring uses bamboo and fast-growth low-density wood. Thin layers of high-density bamboo composites are used to overlay on surfaces of a core layer which can be the composite of wood veneer and wood strand-based composite, or wood veneer and bamboo stripe sheet composite. This invention combines the benefits of bamboo and wood materials to produce a bamboo-wood composite board having sufficient mechanical and physical strength and durability for use as container flooring.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] Pursuant to 35 U.S.C. § 119(a), this application claims the benefit of earlier filing date and right of priority to Chinese Application No. 031528414, filed on Aug. 27, 2003 entitled “A Kind of Container Flooring and Its Manufacturing Method”, the contents of which are hereby incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION [0002] The present invention relates to a composite board suitable for use as a container flooring material. [0003] Container shipping revolutionized the shipping industry in the 1950's. A container body could be moved from a tractor-trailer and placed it fully-loaded on a ship, a railroad car, or even an airplane. Ocean shipping in this manner saves the tedious, expensive, and time-consuming job of unloading cargo from a truck or a railroad car, loading it into the hull of a ship and reversing the process at the ship's destination. A standard container can carry up to 20 tons (U.S.) full...
