Abstract:
Cost effective braid reinforced composites are a potential substitute for metals
in many automotive structural applications where good mechanical performance
combined with high energy absorption are of special interest. This paper
presents experimental work undertaken to characterise braided composites and a
meso-mechanical damage model suitable for the impact and crash analysis of
braided composites. The model presented correctly represents stiffness, initial
failure and the post failure damage response, which is of particular importance
for crash applications. Furthermore, work is presented that describes testing
procedures, which should be followed in order to obtain the correct material
parameters for analysis. Finally, validation of the testing procedures and the
constitutive model is made against a structural braid reinforced composite beam
loaded to failure under four point bending.
