Overview

Investigation reveals enhanced impact energy absorption in carbon fiber composite honeycomb core, indicating superior properties for aerospace and automotive applications.

Key Points

  • The research aims to evaluate the compression behavior and impact energy absorption of a carbon fiber reinforced composite honeycomb core.
  • Designed and fabricated CF-reinforced composite honeycomb core using compression molding.
  • Manufactured corrugated CF composite sheets and bonded them to form honeycomb structures.
  • Attached composite face sheets using film adhesive for sandwich structure testing.
  • Performed comparative analysis with conventional honeycomb cores made from meta-aramid paper and aluminum.
  • CF composite honeycomb core exhibited superior compression modulus and compressive strength.
  • Achieved a better strength-to-weight ratio compared to conventional core materials.
  • Demonstrated enhanced impact energy absorption with higher peak load and reduced indentation depth.
  • Showed smaller damage extent around the impact site than both aluminum and meta-aramid paper cores.
