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
practical applications due to a lack of experimental data. To the best
knowledge of the authors, no experimental investigation has ever
been conducted on the dynamic properties of the luffa sponge
material.
