Abstract :
A novel route for production of auxetic fibres has been adapted from conventional melt
extrusion techniques. These fibres were reproduced, characterised and tested, for the first
time, to assess the potential of auxetic fibres as reinforcements in composite materials.
Initial experimental work has included the embedding of single fibres in modified epoxy
resin. Auxetic fibre specimens were then compared with conventional fibre specimens
through a specially designed fibre pullout testing procedure. The auxetic specimens
displayed superior anchoring properties. The average maximum force at de-bonding of the
auxetic fibres (0.95 N) was observed to be over 100% higher than that for conventional
ones (0.44 N) and the average energy required to fully extract the auxetic fibre from the
modified resin was 8.3 mJ while the conventional fibre required only 2.5 mJ on average.
The results indicate that composites employing auxetic fibres as the reinforcement phase
will exhibit enhanced resistance to failure due to fibre pullout.
