Preparation of TiB2–SiC composites toughened with interlocking microstructure by self-assembled TiB2 plates

Tailored Catalysis Inducing Exceptionally Fire-Safe and Mechanically Reinforced Epoxy at An Ultralow Loading

“…Subject to external force (e.g., tensile and impact modes), the stress was concentrated on the interface between epoxy and LDH-DBS nanosheets. A strengthened interlocking interface between LDH-DBS nanosheets and epoxy matrix formed via porous Fe x S y nanoflakes assembly penetrated by epoxy resin favored the interfacial stress transfer and contributed to the tensile strength. , Additionally, an interlocking interface when subjected to external impact was capable of terminating the initiation and propagation of microcrack (Figure S6), resulting in a rougher fracture surface and improved impact strength. , …”

The comparison in Figure 11a,b revealed a highly efficient fire retardancy of EP/2LDH-DBS@Fe x S y , particularly in the critical loading (2 wt %) to pass the UL-94 V-0 rating.…”
