The Effect of PVP Addition on the
Mechanical Properties of [84%LLDPE: 15%(( 100- ) %PP: X%PVP):
1%Basalt Particle] Polymer Blend Composites |
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. |
