Ravi kumar.M, Keerthiprasad.K.S

This paper presents the delamination resistance of Hybrid Composites Laminates made from Hemp and E-Glass. Two different types of laminates were fabricated by hand lay-up technique; (i) hemp fiber epoxy matrix laminates and (ii) E-Glass fiber epoxy matrix laminates. The hybrid composites are more advanced composites in the present world, they have more than one reinforcing phase and a single matrix phase or vice-versa and even possible with multiple reinforcing and multiple matrix phases. This paper brings out the salient features of indigenously developed test equipment for testing localized, penetrating impact on hybrid composite panels. The dimension of the panels in 60*60 mm2 with a typical thickness of 3.6 mm. The impact velocities are in the region 3-7 m/s, with an imp actor mass between 5-10 kg. Using this equipment laminated composites, panels and can be tested to assess the resistance to falling weight in low velocity test.
