Mechanical and thermal properties of kenaf fiber and montmorillonite reinforced recycled polyethylene terephthalate/recycled polypropylene composites

Mechanical and thermal properties of kenaf fiber and montmorillonite reinforced recycled polyethylene terephthalate/recycled polypropylene composites

The feasibility of developing kenaf fiber (KF) reinforced recycled polyethylene terephthalate (rPET) and recycled polypropylene (rPP) with comparison to two different reinforcing fillers, KF and montmorillonite (MMT) reinforced rPET/rPP was studied. In addition, the compatibilizer of ethylene vinyl...
