Abstract

Polymer blends composites were prepared according to the formula [84%LLDPE:15%((100-X)%PP:X%PVP):1%B.P] with weight ratios selected for X values (0,4,8,12,16 %), as strips by double screw extruder and use press process the strips to prepare the samples according ASTM specification, the mechanical properties were studied for all theprepared samples which are (tensile, flexural, compression, impact, hardness, and creep tests). The results are as following:- results showed increment of mechanical properties as PVP ratio increases except elongation, furthermore the results recorded highest values of fracture strength, young modulus, compressive strength, flexural strength, maximum shear stress, flexural modulus and creep modulus at PVP 8% wt. which are (31.32MPa, 0.14GPa, 27.4MPa,24MPa, 0.6MPa, 1.08GPa and 0.558GPa) respectively.
While the highest values of fracture toughness and hardness recorded at 12% wt. (1.4696Pa√m), and at 4% wt. (56.5) respectively.
