Effect of Fibre Loading on the Mechanical Properties of Waste Newspaper Reinforced Unsaturated Polyester Composite.

Abubakar Aliyu, Malachy Sumaila, Kulla Malam Dangana.


Abstract
This paper presents the usage of waste newspaper particulate (WNP) as a source of reinforcement
in polymer composite production. The surface of the WNP was modified using alkaline (NaOH)
and silane [3-(trimethoxy silyl) propyl methacrylate] treatment. Different weight percentages of
WNP were compounded with polyester. Tensile, flexural, impact and hardness test were performed
to obtain the mechanical properties of the compounded composite material. The results obtained
for Tensile Strength (TS) and Tensile Modulus (TM), impact test and hardness values showed an
increase as the percentage of the waste newspaper particulate reinforcement increased. An
increase of 29.45% for TS was observed, 34.95% for TM and 49.21% for impact energy. However,
the flexural strength was observed to decrease filler loading was increased with the maximum
value of 57.29MPa at 5wt%.

Key words: Waste Newspaper Particulate (WNP), Filler Loading, Tensile Strength, Tensile Modulus, Flexural Strength, Impact Strength, Hardness Value.
