Natural Bamboo Plywood 0.9 mm, 3 plies, narrow grain, laser safe- 4 sizes available

Natural Bamboo Plywood 0.9 mm consists of three cross-bonded plies 0.25 mm thick each. Glue type UF.

Bamboo is a group of perennial evergreens in the true grass family Poaceae, subfamily Bambusoideae, and tribe Bambuseae. Giant bamboos are the largest members of the grass family. In bamboo, the internodal regions of the stem are hollow in many species, and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement.

Bamboo is tough and strong. Bamboo thatch consists of cellulose fibres, like a tree, but unlike wood, its long fibres contain lignin and silica.
The hollow morphology of bamboo combined with the evenly distributed nodes on the stem increases its lateral strength.
Its fibres have a tensile strength of 40 kp/mm², higher than any other ordinary wood fibre which reaches 5 kp/mm², and higher than structural steel fibre which goes 37 kp/mm². In addition, bamboo is soft, light and flexible.

The Brinell test consists of measuring the mark left in the wood by a hard steel ball of 10mm diameter subjected to a load of 500 to 3000 kg, depending on the case.
The interpretation of the test is the calculation of the relationship between the area of the mark left by the ball and the force at which it falls.
According to this test, bamboo is 27% harder than American red oak and over 13% harder than American maple.
