Accelerated weathering performance of cement bonded fiberboard

摘要: Some mechanical and physical properties including total color changes of the cement bonded fiberboard exposed to accelerated weathering process have been investigated. The effects density, wood fiber/ ratio percent accelerator used on weathered boards were determined. Comprehensive sets replicated test data generated in laboratory conditions analyzed statistically. results obtained this study indicative significant performance fiber based fiberboard. Weathering tends decrease all measured. Increase density accelerators generally causes an increase boards. It was realized that / resulted modulus rupture, thickness swelling, water absorption while a elasticity. Percent also cause swelling absorption. Total board found be only effected by used.
