Abstract

Thermoplastic Polyurethane (TPU) exhibits good elasticity, impact resistance, and viscoelastic properties, making it promising for energy dissipation applications. Fused Filament Fabrication (FFF) enables the development of complex structures, including lattice, auxetic, and Triply Periodic Minimal Surfaces (TPMS). This systematic review analyzed 50 articles published between 2020 and 2026 from Scopus/ScienceDirect, Nature, and MDPI using the PRISMA 2020 approach. The review focused on energy dissipation mechanisms, TPU composite engineering, and structural design optimization. The synthesis showed that TPMS improved energy dissipation efficiency by 30–40% compared with honeycomb structures, while auxetic structures increased impact energy absorption by up to 45%. Adding graphene, carbon nanotubes, and TPU/PLA blends increased mechanical modulus by 20–60% but could reduce the damping ratio by 5–15%. Material engineering supports manufacturing stability, whereas geometric optimization primarily determines energy dissipation performance. Key research gaps include multifunctional materials, functionally graded TPMS, and machine-learning-based optimization.

Abstract

Ultra High Molecular Weight Polyethylene (UHMWPE) is a polymer material widely used in ballistic protection systems due to its low density, high specific strength, and excellent energy absorption capability. This article aims to systematically review various UHMWPE reinforcement methods, compare their effectiveness, identify the most promising methods, and evaluate their effects on the mechanical properties and energy absorption performance of the material in ballistic protection applications. The method used is a systematic literature review following the PRISMA framework (Identification, Screening, Eligibility, and Inclusion). Literature was collected from the Scopus, ScienceDirect, Web of Science, and Springer databases in period 30 years. Of the 86 articles initially identified, 42 articles met the inclusion criteria and were analyzed descriptively and comparatively, covering crystallinity modification, gamma irradiation crosslinking, vitamin E stabilization, and the incorporation of reinforcing materials such as graphene, carbon nanotube, aramid, and carbon fiber. The results indicate that increased crystallinity and crosslink formation improve hardness, tensile strength, wear resistance, and structural stability under impact loading. The addition of vitamin E effectively inhibits oxidative degradation and improves fatigue resistance by approximately 30%, while nano-based fillers such as graphene nanoplatelets and carbon nanotubes significantly enhance mechanical strength and energy dissipation capability. Overall, the combination of gamma-irradiation crosslinking with nano-filler reinforcement shows the greatest potential for improving the performance of UHMWPE as a lightweight ballistic protection material with high energy absorption capability.
