Resilience of the ball from the hardness of the sports hardwood floor
A. Hardness of sports solid wood floor - the hardness of wood (that is, the hardness of various woods) is expressed by the hardness of Henkel. Schiehenel hardness is the indentation of steel measured in kg/MM.
Pine - 1.9 kg/MM
Maple—2.7kg/MM
B. Fastness of sports solid wood flooring - Fastness is an important data for measuring the ability to withstand abrasion. Different tree species have different fastness, but they are all determined by wood rings and their growth conditions.
Pine—1.0
Maple—1.49
The data listed above shows that the rebound force of the ball on the sports solid wood floor is the best and largest 95.9% rebound force on the sports wood floor of the common tree species, maple (hard maple). The rebound force of the ball is determined by taking the cement floor as 1, and the rebound rate of the ball is determined by the elasticity of the cement floor.
