The effects of polypropylene fibers on the properties

EFFECTS OF NANOPARTICLE FILLER ON THERMO-PHYSICAL ...

Poor bonding with its accompanying matrix remains the major factor that inhibits the widespread use of natural fiber as filler for composite materials. Recent literature has suggested that this matter can be addressed by applying fillers in nanometer size. Thus, the present study is carried out to investigate the effects of incorporating rattan powder of nanoparticle size into polypropylene ...
