Recycled fibres and fibre sludge as reinforcement materials in injection moulded PP and PLA composites
Abstract
Wood flour or sawdust is often used as filler inconventional wood plastic composite (WPC) materials.However, there has been an increasing interest to the useof wood pulp fibres in reinforced plastic applications,because they can provide enhanced strength properties andbetter biodegradability characteristics for thecomposite. This research compares the effect of recycledfibres or side streams of paper as reinforcement inpolylactic acid (PLA) or polypropylene (PP) composites.Fibre material from liquid packaging board, non-deinkedold newspapers and fibre sludge from recycling processesare compared with virgin softwood kraft pulp fibres.Composites were produced by melt processing to a fibrecontent of 30 wt.% (or 10 wt.% fibre sludge), and themechanical properties were investigated. Recycled fibresprovided comparable, or even higher, plasticreinforcement than virgin softwood fibres. Inpolypropylene composites, the differences in mechanicalproperties between different fibre types were relativelysmall. Fibre sludge decreased the mechanical performanceof composites but can be considered as cheap filler incases when mechanical properties are not crucial. Thepossibility to use low-cost materials like recoveredpaper or deinking sludge in wood plastic composites is aninteresting option for future sustainable applications.
