Description: Properties of particleboard manufactured entirely from recycled particleboard were tested The method for processing three-layer particleboard from all-recycled particles was described. Dynamic MOE (modulus of elasticity) before and after re-manufacturing was tested by a longitudinal stress wave technique. Some stress wave techniques were compared. Nondestructive AU (acousto-ultrasonic) techniques were used to evaluate static, dynamic, and dimensional properties of re-manufactured boards. The results showed a large decrease in mechanical and physical properties for remanufactured boards made from the boards that had higher density. AU parameters corresponded with density in the volume between the surface of transducers. Correlation between static MOE and dynamic MOE was improved by using the AU calculated density. Water absorption and thickness swell corresponded with the AU calculated density.

Keywords: Particleboard. AU (acousto-ultrasonics), recycle. remanufacture, dynamic MOE (modulus of elasticity), MOR (modulus of rapture), density, water absorption
