Abstract
An apparatus and method for testing the physical properties of a material is disclosed. Preferably, the physical properties that may be tested include, but are not limited to, the COR of a material. Accordingly, the apparatus includes a projectile that may be capable of being propelled towards a material sample. The projectile is preferably aimed and fired through a tubular barrel towards the material sample. The tubular barrel preferably comprises a propulsion system that controls pneumatic energy via a pneumatic valve. At least two sensors are placed between the tubular barrel and the material sample in order to detect the passage of the projectile. It is desired that the sensors are placed at precise, discrete positions. As the projectile passes through the field of view of each sensor, the time is recorded to a memory, for example, a counter timer board. The projectile may then impact the material sample, which may preferably be held in place by a fixation device. The fixation device is preferably a holding slot, which may be backed by an infinite mass cylinder. Upon rebounding from the material sample, the projectile passes back through the field of view of the sensors in reverse order, allowing the sensors to capture and record the time of passage to a memory, such as a counter timer board. The physical properties of the material sample may be calculated by a processing device that is operatively connected to at least a portion of the apparatus.
