Dehnungsaufnahme und röndt-genographische Elastizitätskonstanten in faservestärkten Polymeren

For high-performance polymers PEK (Polyetherketone) and PBT (Polybutylenterephthalate) (nonreinforced and reinforced) the mechanical X-ray compound-elastic constant (XEC) were calculated by the mechanical data (Young%-modulus and Poisson's ratio of each phase) with the help of Eshelby/Kroner model. Experimental results of XEC of PEK+C-fibers, PBT+glasspheres and PBT+glasfibers were compared with the calculations and discussed. The result shows that the these semi-crystalline polymers, the influence of different kind and ratio of reinforcement on XEC can be nearly determined considering the macroscopic Young's-modulus.
