It was found that the phosphorus-containing unit was successfully anchored onto the PLDH. The prepared FEA@PLDH solution with a viscosity of 146 mPa·s exhibited good interfacial compatibility with the ethylene-vinyl acetate (EVA) surface. Taking advantage of the synergistic catalytic carbonization and expanded insulating barrier effects of FEA@PLDH, the corresponding coated EVA (EVA-FEA@PLDH1) with 1 wt% of PLDH could form a continuous and compact carbonaceous block layer under fire or high-temperature conditions. Meanwhile, the LOI for EVA-FEA@PLDH1 was increased from 22.0% to 32.0% and reached the UL-94 rating of V0. Moreover, EVA-FEA@PLDH1 showed delayed TTI (77 s) and T<sub>PHRR</sub> (146 s), with 6% and 44% reductions in THR and TSP, respectively, and 43% increment in residual char, as compared to the EVA-FEA. In addition, fire resistance experiment revealed that EVA-FEA@PLDH1 could withstand the ∼1300 °C flame for 467 s longer than that of the EVA-FEA (171 s).

It was observed that the mechanical characteristics of manufactured bio-composites are negatively affected by the high concentration of ash gourd peel particles in the epoxy matrix. Also, increasing ash gourd peel particle fraction increases the water absorption of composites when immersed in distilled, sea, and tap water. The composite with 5% filler by weight absorbs water at a minimal rate when immersed in seawater.
