Abstract

The damage zones in three different knitted glass-fabric (GF) reinforced polypropylenes (PP) were studied on SEN-T specimens simultaneously by acoustic emission (AE) and infrared thermography (IT). The composites have different fiber contents and additives. The fracture toughness, the size of damage zone and the acoustic events were measured and calculated. The results showed that the effect of additives was bigger than the increase of the fiber content.
