Overview

This research examines mechanical performance in sandwich structures using 3D printed composite core geometries, suggesting improved applications.

Key Points

  • The study aims to enhance mechanical properties of sandwich structures by optimizing composite core geometries.
  • Used 3D printing technology (FDM) to create trihexagonal, hexagonal, and triangular core geometries.
  • Incorporated Kevlar fiber and aluminum as facing sheets.
  • Evaluated mechanical performance through impact tests, shear stress tests, and compression tests.
  • Trihexagonal core achieved highest energy absorption with peak impact energy of 16.5 J at 600 mm and 27.66 J at 1,100 mm.
  • Triangular core reached maximum load-bearing capacity of 7,000 N.
  • Hexagonal core demonstrated superior resilience during testing.
