Thermoplastic composites are gaining more and more interest in automotive, aerospace and sports applications, because of the short cycle times and recycling possibilities. Besides short fibre-reinforced thermoplastics, also continuous fibre-reinforced thermoplastic composites are being considered for load-carrying structures. However, their behaviour during manufacturing and during in-service use is very different from the traditional thermoset composites (typically epoxy-based). The mechanical properties of thermoplastic composites are much more sensitive to temperature and loading rate. The combined effect of temperature and loading rate complicates the modelling of the elasto-plastic response of thermoplastic composites. Moreover, thermoplastic composites with a semi-crystalline polymer matrix can have varying degrees of crystallinity, depending on the processing conditions.
UGent-MMS has a PhD vacancy for 3 years on a large research project with a strong industrial consortium. The purpose is to characterize the thermomechanical behaviour of thermoplastic composites, by combining a diverse set of experimental testing methods (DSC, DMA, mechanical testing at different temperatures and strain rates). Those tests should be combined with dedicated instrumentation methods to provide valuable insights into the thermomechanical behaviour of thermoplastic composites.
