Formula One race cars have to pass rigorous safety tests before they are
allowed on track. This type of testing has been in place for years but the
requirements for testing are continually increasing in order to reduce the
amount of risk to the drivers’ safety during a race. The number of structures that
need to be made and tested can quickly make this process an expensive one.
Additionally, it is necessary to pass the mandated tests within a reasonable
amount of time so as not to have an impact on the development on the rest of
the car. There is a desire to reduce the number of structures needed for testing
through finite element analysis (FEA), and as such, to reduce the time needed
to pass the safety tests. FEA of laminated composites can be complex and is a
balance between accuracy and the time it takes to find a solution.
The current project looks into increasing understanding of the requirements for
material characterisation, experimental impact testing, and explicit simulation of
a carbon fibre fabric pre-impregnated with epoxy resin. Mercedes-Benz Grand
Prix (MGP) Formula One Team has provided a pre-preg material for evaluation.
Material experiments were performed per the American Society for Materials
and Testing (ASTM) in order to find the tensile modulus, tensile strength,
Poisson’s ratio, compressive strength, shear modulus, and shear strength of the
material. Nine tubes were manufactured at MGP and tested in the drop tower at
the Cranfield Impact Centre (CIC) ... [cont.].
