The Effect of Fiber Orientation and Laminate Stacking Sequences on the Torsional Natural Frequencies of Laminated Composite Beams
The PPPP-treated laminate exhibited approximately the same energy absorption trend as that of the PPPP-untreated laminate, with a 10–20% improvement. The PPPP-untreated sample exhibited approximately 50% energy absorption at low impact energies of 5 and 10 J. This demonstrates that some energy is dissipated and that not all the energy supplied to the laminate is […]
