is growing in our society because of the search for sustainable solutions
using new materials. In a recent study [3], the authors
discovered that under quasi-static loading the luffa sponge material
exhibits remarkable stiffness, strength and energy absorption capacities
that are comparable to those of a variety of metallic cellular
materials.
A limited amount of research has been conducted on the luffa
sponge as a source of bio-fibres and bio-composites in the last ten
years. The previous research indicated that it is a potential alternative
material for water absorption [6,7], and waste water treatment
[8,9]. The luffa fibres were also used as reinforcement fibre for
other materials [10e14] and cell immobilization for biotechnology
[15e18]. At the same time, the sponge gourd of LC, the origin of luffa
sponge material, has not yet had their potential fully explored. With
regard to the industrial and technological development, the cost of
fuel is on the increase. Oil is extracted from seeds for industrial use
[6]. The seed of LC is used as oil sources. The oil extracted from LC is
finding increasing use in the production of biodiesel which is now
gaining acceptance because of low CO2 emission and other considerations
[19].
However, there is a lack of scientific data on the mechanical
properties of luffa sponge material because up to now its main
practical use has been as a body scrub in the bathroom. The luffa
sponge material and luffa fibres have so far found very limited
