The aim of this study is the evaluation of fatigue strength of
glass-fibre-reinforced polypropylene composite (PPGF35) by applying both
the Risitano Thermographic Method (RTM) and the new static Thermographic
Method (STM). Fifteen tensile tests and twenty cyclic tests were carried
out to evaluate the fatigue strength of PPGF35 by applying traditional
and innovative energy methods. The results show how the energy methods
used are very useful for rapid identification of the material’s fatigue
strength, saving companies time and money.
