Abstract
Development for introducing new material technology and new structural design technology in ski poles has been conducted in recent years. Although the CFRP pole is light, the impact is strong. The shock absorbing characteristic of the FRP is important for the application of robot arm and ski pole etc. In this work. the theoretical method was suggested about shock absorbing characteristic. An impact test apparatus was developed for verify the theory and this calculation method. The agreement obtained between the theoretical and the experimental values of seven types of laminated composite cylinders, these being unidirectional (0°, 90°) plies, cross-plies (±15°, ±30°, ±45°, ±60°, ±75°) plies. It shows that the mathematical technique developed here is satisfactory for predicting the shock absorbing values (maximum impact load) of laminated composite cylinders. Shock absorbing characteristic of laminated composite cylinder varies with fiber orientation angle. Effect of EL is large in near at 0°, and effect of GLT is large in near at 45°about maximum impact load.
