摘要: To investigate the influence of moisture and EPR-g-MA content on fracture behavior glass–fiber reinforced PA6 materials, brittle-to-tough transition temperatures (Tbtt) were determined. Water absorption was taken into account by conditioning analyzed materials. Tensile tests could reveal temperature range largest dependence mechanical properties between 10 50°C. J-integral values used to describe under conditions impact load as a function temperature. The polyamides found be less approximate than in unreinforced Two different characteristic points Ts Te identified, which intercept elastic elastic–plastic deformation one hand starting point dominating stable crack propagation with strong plastic other hand. Characteristic Tbtt calculated arithmetic average these two points. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
