The failure and crashworthiness performance of hybrid Polylactide (PLA)/Glass Fiber Reinforced
Polymer (GFRP) composite tubes subjected to axial and radial quasistatic compression loads were
investigated in the present study. The composite tubes are fabricated using hand lay-up and Fused
Deposition Modeling (FDM)-filament winding processes. The crashworthiness performance was
studied using parameters such as the peak load, energy absorption, crush load, crushing load
efficiency, and specific energy absorption. The highest peak loads from the compression test
results in the axial and radial directions are calculated using variations in the filament winding
PLA/GFRP (FPG) specimen, whose values were 16130.50 N and 12077.33 N, respectively. The
highest mean crush load is found in the material variation with the FPG specimen, which is
5734.43 J/mm for axial loading and 4886.75 J/mm for radial loading. The highest energy ab
sorption (EA) value is found in the material variation with the FPG specimen, which is 262.18 J
for axial direction loading and 94.02 J for radial direction loading. The highest specific energy
absorption (SEA) value is found in the material variation with the specimen Filament Winding
PLA/GFRP, which is 16.92 J/g for axial loading and 10.98 J/g for radial loading. There are three
main types of failure of the composite: matrix cracking, fiber damage, and folding. The study
showed that by combining Additive Manufacturing and composite lamination, the hybrid PLA/
GFRP specimen outperformed the existing structures.
