The impact response and material damage influenced by intralaminar and interlaminar TPU were investigated separately through low-velocity impact. Experimental results show penetration energy for the laminates with TPU soft phase was significantly enhanced, with the value of 5 J, 12.5 J, and 10 J for type A, B, and C, respectively, in which the type B with TPU films inserted between layers has the maximum increase percentage by 38 %. Thus, TPU interleaves can improve penetration energy more effectively than the intralaminar TPU phase. Failure is divided into three categories including no penetration, tough penetration, and brittle penetration, as characterized by different failure modes. Interestingly, the laminates with TPU phase displayed tough penetration while baselines without TPU can only present brittle penetration with even more fabrics included. Permanent deformation was observed for specimens with TPU phase after penetration instead of obvious delamination and fiber bundle breakage appeared in baselines. In general, hard and soft strategies with TPU phase can prevent sudden catastrophic failure under high-energy impact.

In this study, the high brittleness and low toughness of epoxy resin (EP) are addressed by incorporating hydroxyl-terminated polyether-sulfone (PES-OH) and nano-silica (Nano-SiO<sub>2</sub>) into the EP. The incorporation of PES-OH into EP led to a 22.6 % increase in tensile strength and a 27.8 % improvement in elongation at break at ultra-low temperatures. These enhancements are attributed to the formation of a semi-interpenetrating polymer network (SIPN) during the curing process, which strengthens the molecular network of the epoxy resin matrix through physical entanglement, interfacial reinforcement, and stress dispersion, enhancing crack resistance. The simultaneous introduction of PES-OH and Nano-SiO<sub>2</sub> synergistically improves the mechanical properties of EP at ultra-low temperatures (90 K). Specifically, the tensile strength, elongation at break, and modulus of elasticity of the modified EP were increased by 30.63 %, 19.6 %, 20.9 % and a 65.61 % improvement in fracture toughness (K<sub>IC</sub>), respectively, compared to the pure EP. The synergistic effect arises from the covalent bonding between the hydroxyl groups on Nano-SiO<sub>2</sub> and those in PES-OH and EP, thereby toughening and strengthening the epoxy molecular structure.

In this study, a novel multifunctional flame retardant (P-N@CoFe-PBA) was synthesized by decorating cobalt-iron Prussian blue analogue (CoFe-PBA) onto the surface of a P-N FR. The results showed that P-N@CoFe-PBA significantly improves the flame retardancy, smoke suppression, toxicity reduction, and antimicrobial properties of TPU composites.

The improvement in flame retardant performance of TPU-6 %P-N@CoFe-PBA is due to the catalytic carbonization ability of P-N@CoFe-PBA, which promotes TPU composites to form an excellent char residue layer structure, providing effective thermal insulation and preventing mass transfer. Furthermore, P-N@CoFe-PBA suppresses the generation of toxic gases and flammable volatiles during combustion and imparts antimicrobial properties to TPU.
