In response to the impact damage tolerance issue of T800 grade carbon fiber reinforced composite laminates, this paper establishes a numerical simulation analysis method for impact and post impact compression. Based on this numerical analysis method, the influence of layup method on the impact resistance of composite laminates is analyzed and studied. The analysis results show that reducing the 90° layup ratio appropriately can effectively improve the impact resistance of composite laminates.

摘要

In response to the impact damage tolerance issue of T800 grade carbon fiber reinforced composite laminates, this paper establishes a numerical simulation analysis method for impact and post impact compression. Based on this numerical analysis method, the influence of layup method on the impact resistance of composite laminates is analyzed and studied. The analysis results show that reducing the 90° layup ratio appropriately can effectively improve the impact resistance of composite laminates.
