In this study, the effects of screw configuration, screw speed and silica content on the physico-mechanical and foaming properties of PP/wood-fiber (WF) composites were investigated. PP/WF composites were produced by the intermeshing co-rotating twin screw extruder. Microcellular closed cell PP/WF composite foams were prepared using pressure-quench batch process method. Firstly, an attempt has been...
The mechanical properties, flame retardancy, thermal degradation and foaming properties of wood–fiber/PP composites have been investigated. Ammonium polyphosphate (APP) and silica were used as flame retardants. The limiting oxygen index (LOI), thermal gravimetric analysis (TGA) and cone colorimeter (CONE) were employed for the study of fire retardance. At the same time, wood–fiber/PP composite foams...
