their own sustainable development.
The focus of the research work described in this paper was to use the fibres extracted from the fronds, as well
as the coir, for the reinforcement of
natural fibre composites to be used in
applications such as automotive, construction, sporting goods, aerospace,
and marine, as shown in Figure 2(b).
Benchmarking
To have a fair comparison between
different fibres, specific properties were
considered. The specific strength of
treated date palm frond fibre (DPFF)
is higher than hemp and comparable to
that of flax and glass, as shown in Figure
3(a), while its specific modulus is higher than flax and comparable to glass, as

shown in Figure 3(b) [1-3].
On the other hand, the annual world
availability of date palm residues is
comparable to the annual world production of glass, and it is an order of
magnitude higher than hemp and flax,
as shown in Figure 4(a). Further, the
price of DPFF in the field is negligible,
as can be seen in Figure 4(b), since it is
a by-product that has no applications,
and farmers either burn it in the field
or dump it in the landfill [4].
Boeing-Cayley case study
In 2012, Boeing partnered with
several SMEs with the purpose of
developing
environment-friendly
aircraft interiors from natural fibre
composites. The project was funded
by the EU Eco-Innovation award with
a budget of almost €0.8 million. They
were able to develop overhead locker
panels and sidewall panels from woven
flax composites, as shown in Figure 5.
The produced panels conformed to
the stringent aerospace performance
requirements in terms of strength,
flammability, acoustic properties and
weight [5]. They even endeavoured to
industrialize the production process,
and reduce the production cycle.
Date palm fibre composites
The use of date palm fibres in the reinforcement of polymeric composites
has been investigated before, however,
but most of the prior research was
limited to using untreated chopped
whisker fibres of ~5 mm length as
fillers in plastics, with a random
orientation and very low fibre volume
fraction. Thus, they could not harness
the full potential of such fibres. In this
research, long fibres (L=30 cm) were
extracted from the fronds and, during
