showed that 109 kg of flax fibre (i.e.
1/5 ha of flax culture [6]), 33 kg of
balsa, cork and plywood, and 280 kg
of partially bio-based polyester resin
were used in total. Increased resin
uptake was noted compared to the
original Tricat due to the low density
of the natural fibres (+60 kg resin
compared to the glass composite) and
to the use of consumables to adapt
the lateral hull moulds to the infusion
process (+40 kg compared to the original lay-up process). The LCA results
will be used to assess the impact of
this difference. LCA is also being used
in collaboration with the University
of South Brittany for in-depth studies
on the impact of different end-of-life
scenarios (burning and landfill) and
on the impacts of the competition
between biomaterials and food production. n

be taken to study weight gain and
ageing effects.
Environmental issues
Many publications have shown that
bio-based composites offer comparative environmental advantages
[5]. By making a boat prototype,
the partners have demonstrated that

these materials can also show good
mechanical properties. A full life
cycle assessment (LCA) is underway
to evaluate whether the use of the
bio-based composite is still positive in
this type of application, compared to
the same glass fibre/polyester trimaran, and where further research and
development is needed. An inventory
