| Abstract: |
| Wood-plastics composites(WPC) was prepared by means of mixing processing and compression molding using old newspaper and recycled-polypropylene(rPP) as raw materials. The effects of the fiber content on the mechanical properties and absorption properties of WPC were investigated. The structure of composite was characterized by means of FT-IR and SEM. The results showed that， old newspaper fibers could be used as reinforcement for rPP based composites. When the wastepaper fiber loading was 30%， the tensile strength and flexural strength of the composite reached the maximum 32.36 MPa and 43.37 MPa， improved by 66.1% and 69.6%， respectively compared with the composite without recycled ONP fibers. With the increasing of fiber content， the peak to hydroxyl (—OH) of the composite in the IR spectrum increased gradually， and the water-absorption of the composite exhibited a gradual increasing trend. The SEM images of fracture section of the composite indicated that， when the fiber content was low， good interfacial properties existed between the fiber and the rPP. When the fiber loading exceeded 30%， interfacial compatibility decreased obviously. |
