Overview

Experimental investigation showed increased tensile and flexural strength in carbon fiber composites, indicating improved performance.

Key Points

  • Tensile strength of sandwich composites increased by 64.5% compared to unreinforced specimens.
  • Flexural and impact strengths saw improvements of 24.5% and 69.0% respectively against unreinforced controls.
  • The hand lay-up method combined with 3D printing resulted in lightweight, high-strength composites.
  • Significant reductions in water absorption and density were observed in the new composite design.
