Container flooring material and method of manufacture

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.

1 . A bamboo-wood composite board comprising: 
 (a) at least one surface layer comprised of a plurality of bamboo stripe sheets and resin;    (b) a core layer comprising at least one wood veneer layer and a support layer.    
     
     
         2 . The board of  claim 1  wherein the support layer comprises a wood strand layer or a wood veneer layer oriented perpendicular to the at least one wood veneer layer.  
     
     
         3 . The board of  claim 2  wherein the core layer comprises least four layers of wood veneers, alternating between grain parallel and grain perpendicular layers.  
     
     
         4 . The board of  claim 3  wherein the support layer further comprises at least one bamboo stripe sheet.  
     
     
         5 . The board of  claim 3  wherein the core layer comprises 17 layers of wood veneers, alternating between grain parallel and grain perpendicular layers.  
     
     
         6 . The board of  claim 3  comprising two surface bamboo layers, sandwiching the core layer.  
     
     
         7 . The board of  claim 2  wherein the support layer comprises a wood strand layer.  
     
     
         8 . The board of  claim 7  wherein the wood strand layer is an oriented strand layer.  
     
     
         9 . The board of any preceding claim wherein the wood comprises a wood having a specific density of about 0.6 or less.  
     
     
         10 . The board of  claim 9  wherein the wood comprises poplar, aspen, spruce, fir, or pine.  
     
     
         11 . A bamboo-wood composite board comprising: 
 (a) at least one surface layer comprised of a plurality of bamboo stripe sheets and a resin;    (b) a core layer comprising a wood strand layer.    
     
     
         12 . The board of  claim 11  wherein the wood strand layer comprises a low-density wood material.  
     
     
         13 . The board of  claim 12  wherein the low-density wood material is selected from the group consisting of poplar, aspen, spruce, pine or fir.  
     
     
         14 . The board of  claim 11  further comprising a wood veneer layer disposed between surface bamboo layer and the wood strand layer.  
     
     
         15 . The board of  claim 11  wherein the wood strand layer is an oriented strand layer.
