Green additives such as prodegradants based on natural fatty acids and iron can improve the environmental profile of thermoplastic packaging materials. We present two studies in which this is demonstrated. In the first study, the addition of a green

Numerical/Experimental Study of the Impact and Compression after Impact on GFRP Composite for Wind/Marine Applications

Autor: Jens Kjær Jørgensen, Giovanni Perillo

Publikováno v: Procedia Engineering

Damage development due to impact needs to be understood to evaluate the consequences of impact on composite structures. This study concentrates on modelling low velocity impact and consequent compression after impact (CAI) test on thick industrial co

A micromechanical model of crossover fiber bridging is developed for the prediction of macroscopic mixed mode bridging laws (traction-separation laws). The model is based on moderately large deflection beam theory and takes fracture of the bridging l

Measuring deformation and mechanical properties of weld lines in short fibre reinforced thermoplastics using digital image correlation

Autor: Jens Kjær Jørgensen, Jakub Kalus

Publikováno v: Polymer Testing. 36:44-53

Weld lines in injection moulded short fibre reinforced thermoplastics can significantly reduce the mechanical strength of a product. However, knowledge about the mechanical properties in the weld line region is limited. A reason for this is the diffi

Aging of polyamide 11. Part 3: Multiscale model predicting the mechanical properties after hydrolytic degradation

Autor: Andreas T. Echtermeyer, Jens Kjær Jørgensen, Tobiasz Mazan

Publikováno v: Journal of Applied Polymer Science. 132

A holistic general multiscale model of polymer degradation has been applied to predict the mechanical properties of polyamide 11 after the hydrolytic ageing. Results for elastic modulus, tensile strength, and embrittlement threshold have been compare
