The research focuses on the preparation composite material containing Low Density Polyethelene (LDPE) and bentonite clay of grain size (75µm) ,followed by calcinations process at (300,500) ºC ,after that poly vinyl alcohol (PVA) solution prepared and used as a bonded layer covered the bentonite powder befor applied as a filler,pluger injection molding method were used to prepare samples which have filler percentage (2.5,5,7.5,10,12.5)% . Many tests have been done including: (Bending test,Impact,Hardness , Compression strength and Tension) .
The research results showed that the values (Bending,Hardness,Compression Strength,Tensile) will increase with the increase of the filler percentage ,in the other hand the values of impact strength will be decrease with the increase of the filler percentage of the all samples used in this research . |
