from a scientific perspective, one could use a texture analyser to measure compressional hardness: stable micro systems ltd. alternatively, a dynamic mechanical analyser would be useful: dynamic mechanical analysis. Free Sample

the high values of the compressive strength and specific compressive and tensile strengths perpendicular to the grain (width direction) shown by the experimental thermoplastic composites compared to wood reveal their great potential for use in compressed elements and in functions where components, Free Sample

the chart above can be used as an informative guide for the hardness of different species of wood. the chart helps determine how difficult it will be to nail, staple, or saw the wood. the higher rating the wood has, then the more durable the wood is. please browse our hardwood flooring products, and we hope you find the, Free Sample
