What is Composite?
Composite materials (or composites for short) are engineered materials made
from two or more constituent materials with significantly different physical or
chemical properties which remain separate and distinct on a macroscopic level
within the finished structure.
Advantages: Lightweight, Good materials properties, etc.

Why is Natural Fibre?
Nature continues to provide mankind generously with all kinds of rich resources
in plentiful abundance, such as natural fibres from a vast number of plants.
However, since the last decade, a great deal of emphasis has been focused on
the development and application of natural fibre as reinforcement in composite
materials in many industries. This is due to the natural fibres composites are
undergoing a high tech revolution and are replacing conventional
composites in high performance applications due to their advantages over
conventional reinforcements. For this reason natural fibres reinforced composite
are applicable and need broader research programmes. Moreover, due to the
relatively high cost of synthetic fibres such as glass, plastic, carbon and
Kevlar used in fibre reinforced composites and the health hazards of asbestos
fibres, it becomes necessary to explore natural fibres, e.g. cotton, sisal, jute,
palm oil, paddy, ijok, etc. In addition, the main advantages of these fibres are
their availability in large quantities in many countries, good thermal and
acoustic insulating properties, better electrical resistance, higher resistance to
fracture and impact absorption, low density, low cost and ease to manufacture.

What is Arenga Pinnata?
IJUK or scientific name is Arenga Pinnata is a type of PALM TREE native to
tropical ASIA (inc. MALAYSIA). Medium size palm (growing up to 20m) and
trunk covered by rough old leaf bases. In this research, the composite material
is made by using IJUK fibre as reinforcement and epoxy resin as a binder.
