Recycled fibres and fibre sludge as reinforcement materials in injection molded composites
Abstract
Usually wood flour or sawdust is used as filler inconventional wood plastic composite (WPC) materials.However, there is also an increasing interest towards theuse of wood pulp fibres in reinforced plasticapplications. This research compares the effect ofrecycled fibres or side streams of paper as reinforcementin polylactic acid (PLA) or polypropylene (PP)composites. Fibre material from liquid packaging board,non-deinked old newspapers and fibre sludge fromrecycling processes are compared with virgin softwoodkraft pulp fibres. Composites were produced by meltprocessing to a fibre content of 30 wt.% (or 10 wt.%fibre sludge), and the mechanical properties wereinvestigated. Recycled fibres provided comparable, oreven higher, plastic reinforcement than virgin softwoodfibres. In polypropylene composites, the differences inmechanical properties between different fibre types wererelatively small. Fibre sludge decreased the mechanicalperformance of composites but can be considered as cheapfiller in cases when mechanical properties are notcrucial. The possibility to use low-cost materials likerecovered paper or deinking sludge in wood plasticcomposites is an interesting option for futuresustainable applications.
