To enhance the mechanical properties of honeycomb structures, a phenolic foam composite meta-aramid core (PFAH) was developed. Experimental, simulation, and theoretical analyses revealed that PFAH increased out-of-plane energy absorption by 89.47% without altering specific aramid honeycomb, maintaining smooth plastic deformation. At 150 °C, it retained 90.7% properties. In in-plane direction, PF raised plateau stress 798.73%. The study identified critical spinodal for off-axis angle deformation modes established relationship between strength angle, demonstrating superior resistance to shallow-angle oblique loading compared unfilled honeycomb.

The sustainable flame retardancy of polymeric materials is a key focus for the direction next generation in field fire safety. Bio-derived retardants are gaining attention as environmentally friendly additives due to their low ecological impact and decreasing costs. These compounds can enhance char formation by swelling upon heating, attributed functional groups. This review explores various biomolecules used retardants, including phytic acid, chitosan, lignin, tannic bio-derived phosphorus nitrogen compounds, emphasizing flame-retardant properties compatibility with different polymer matrices. primary on structural characteristics, modifications, behaviors these additives, particularly regarding mechanisms action within materials. Finally, opportunities, current challenges, future directions practical application
