Jute/polyester woven laminates have been impacted to energies up to 20 Joules with an impact velocity of 2 m/s using a Rosand dropweight impact tower. The diameter of the hemispherical impactor was 12.7 mm. Some of the laminates underwent to post-impact tensile tests to failure on an Instron 9501 testing machine. The aim of these tests was to measure the degradation of their mechanical performances with increasing impact energy. Tensile failure occurred by macroscopic matrix cracking under the point of impact. Here, the interlaminar fracture toughness of this material was sufficiently high that failure did not involve delamination.

Abstract
Jute/polyester woven laminates have been impacted to energies up to 20 Joules with an impact velocity of 2 m/s using a Rosand dropweight impact tower. The diameter of the hemispherical impactor was 12.7 mm. Some of the laminates underwent to post-impact tensile tests to failure on an Instron 9501 testing machine. The aim of these tests was to measure the degradation of their mechanical performances with increasing impact energy. Tensile failure occurred by macroscopic matrix cracking under the point of impact. Here, the interlaminar fracture toughness of this material was sufficiently high that failure did not involve delamination.File in questo prodotto:
