Mixing Recovered Waste Fiber-Reinforced Plastic with Polyethylene Plastic Waste

Abstract

Polyblending was applied to mix waste fiber-reinforced plastic (FRP) and polyethylene (PE) plastic waste in various proportions and particle sizes. Compatibility, morphology, mechanical properties, and dynamical mechanical analyses of the matrix composites were used as indices to justify the physical behaviors of composites. Differential scanning calorimetry measurements and scanning electron microscopy observations showed that PE and FRP in the blends were incompatible. The mechanical strengths of blends were decreased if the FRP ratio or particle size increased. Results of tensile and impact strength tests indicated that the blends had a brittle property.
