Impact Strength and Hardness of Particleboard and Fiberboard

Impact Strength and Hardness of Particleboard and Fiberboard

1 impact strength

The impact strength of particleboard and fiberboard reflects the product’s ability to resist dynamic load damage. The plate with high impact strength has good toughness, whereas its brittleness is greater. Particleboard and fiberboard in the use process, in many cases to resist impact load. For example, floor materials are subjected to impact load as well as static load. Therefore, particleboard and fiberboard are required to have certain impact strength. The impact strength of particleboard and fiberboard is related to material type, thickness, production mode and veneer.

2 Hardness

The hardness of particleboard and fiberboard refers to the ability of the board surface to resist the concave of the residual deformed object when subjected to static or dynamic loads of other objects. The hardness of the board mainly depends on its density, especially the surface density of particleboard and fiberboard. The higher the density of the sheet, the harder it will be. The hardness of particleboard and fiberboard is also related to rubber species, moisture content and whether strengthening measures are adopted. The hardness value is also related to indentation tools.
