Dynamic Energy Absorption of Filament Winding Conical Composite with Different Orientation Angle and Low Velocity

Abstract

Nowadays, the escalation of technology automotive produced a lot of transports. In connection with that, the rates of accident increased also. The application of composites from fiber is many used as a part of transport. The fiber composite used to absorb the impact directly from that accident. Filament winding is one of method to make a composite fiber. In this investigation, mandrel are made from wood with consists of cone with vertex angle 5ºand 10º. Glass fiber filament is use to winding the mandrel with different orientation angle. The orientations angle is 45°/-45°, 90°/45°, 90°/45°/90°, 45°/90°/-45°, 45°/-45°/45°/-45° and 90°/45°/90°/-45°. Resin epoxy used when process of winding start. Then, the specimen will test with impact testing in 4 velocities which 2.7 m/s, 3.1 m/s, 3.4m/s and last 3.8 m/s. Data from that testing will analyst and discuss. In conclusion, the result shown that both vertex angle and fiber orientation controlled the performance of energy absorption capability. The energy absorption increased when impact loading velocities increase. It is observed that different collapse mechanism have characterized the performances of specific energy absorption. The collapse mechanism happened are ring types splitting.
