Natural The influence of adding various natural fibers on

Natural fibers
were used in ancient Egypt and China as reinforcement for building materials
for pyramids and the great wall. In recent years, due to the
increasing environmental awareness, natural fibers have gained popularity by
replacing their synthetic counterparts as light-weight reinforcement for
polymers and inorganic polymers (i.e. geopolymers). The reasons can be
attributed to the fibers’ relatively low cost and low density, acceptable
specific properties, ease of separation, enhanced energy recovery, CO2
neutrality, biodegradability, and recyclable properties. In addition,
natural fibers are durable, reliable, lightweight, and have excellent
mechanical properties. For instance, geopolymers have recently become a
promising ecological alternative to the traditional cementitious material. They
are cost-effective, environmentally friendly and their production involves
relatively small amount of energy. They also have good compressive
strength, durability and thermal properties being highly resistant to flame and
heat. However, geopolymers have relatively low tensile and flexural strength,
which limits their use in many areas. The mechanical properties of
geopolymers can be significantly improved by reinforcement with natural fibers.
The resultant polymer and inorganic polymer composites are significantly better
than those of traditional materials and they are fueling the growing demand for
natural fibers in various industries such as automotive, building, and
construction.

This book provides
an overview on the latest advances in the synthesis, characterisation and
mechanical properties of polymers and geopolymers reinforced with natural
fibers such as pulp-fiber, cotton, sisal, flax and hemp. The influence of
adding various natural fibers on the mechanical properties of these composites
is discussed. Potential applications, challenges, and future directions of
these composites are highlighted and addressed.
