The energy absorption behavior of novel composite sandwich structures reinforced with trapezoidal latticed webs

This article proposed an innovative composite sandwich structure reinforced with trapezoidal latticed webs with angles of 45°, 60° and 75°. Four specimens were conducted according to quasi-static compression methods to investigate the compressive behavior of the novel composite structures. The exper...
