  • Due to the existing defects with extrusion hollow particleboard, such as low longitudinal strength, demand for wood shavings. In order to improve these defects, we study used different specifications for shavings, entity density, and hollow hole distance input factor, along with flat-pressure, to make 30 mm hollow particleboard. Tests were performed on hollow particleboard and analysis of their main physical and mechanical performance was conducted. Results showed that in contrast to extruded hollow particleboard, the mechanical performance was greatly improved with flat-pressure hollow particleboard. In the test range: 1） the mechanical performance of the board made by rod-shaped wood shavings was best. 2） The higher the entity density, the higher number of the longitudinal MOR; the MOR of hollow particleboard with an entity density of 0.70 gcm－3 was nearly 3 times that of the entity density of 0.50 gcm－3. 3） The greater the hollow hole distance, the higher number of the longitudinal MOR. When the wood shavings were rod-shaped, the entity density was 0.70 gcm－3, and the hollow hole distance was 20 mm, then the MOR of the hollow particleboard was 8.24 MPa.［Ch, 5 fig. 3 tab. 9 ref.］
