Impact Experiment and Analysis of the Carbon Fiber Composite Plate with the Central Hole

Article Preview

Abstract:

The composite material plate with the central hole is made by the composite prepreg. During the laying, the circle Teflon sheet is installed into the center of the composite plate. After curing, the center circle area was cut-out and the composite plate with the central hole was observed. Three different central holes are designed by the diameter of 12 mm, 14 mm, and 16 mm. The composite plate with central hole is stroke by the impact-or to measure the absorption energy, and acceleration to compare their impact resistance. The finite element analysis is also used to analyze the mechanical behavior of the plate during and after the impact. The results showed that the energy absorption capability is lower when the central hole became bigger.
