The increasing use of composites in vehicles in recent years is one
of the current trends in the automotive industry. In particular, fiber composites
are being used as reinforcements for the main structural elements of vehicles,
due to their outstanding specific mechanical properties and low weight. When
combined with metal parts, fiber composites can significantly enhance the crashworthiness
of vehicle structures, by increasing their energy absorption capabilities
and resistance to plastic deformations and permanent damage. This work presents
CFRP reinforcements as a case study for enhancing the bending collapse behavior
and crashworthiness of bus structures. The required calculations are based on
a simplified “concept model” that includes the bending collapse behavior of the
structural components, based on theoretical models calibrated with experimental
results. The results demonstrate that the use of CFRP reinforcements improves the
rollover crashworthiness of a bus structure, and need not be applied to the entire
structure, but only to the critical parts where bending collapse is most likely to
occur in a rollover accident.
