摘要

In response to escalating demands for energy-efficient and acoustically optimized materials, this study develops a lightweight interpenetrating network (IPN) composite felt via skeleton fragmentation reconstruction of melamine foam (MF) and ultrafine glass fibers (UGF). Utilizing a scalable wet-laid sheet forming technique, MF was mechanically fragmented and uniformly integrated with UGF at controlled mass ratios (M7G3-M3G7). Comprehensive characterization revealed that the hybrid architecture simultaneously enhances thermal insulation and acoustic performance. Microstructural analysis confirmed a dual bonding mechanism-bridging and interpenetration-between MF trident-like skeletons and UGF, forming tortuous micropores (2–25 μm). Optimal thermal insulation was achieved with M3G7 (30.83 mW/m·K), leveraging synergistic hindrance from organic–inorganic heat transfer mismatches and suppressed convection in narrowed pores. Mechanically, M5G5 exhibited superior compressive strength (> 900 N at 5 mm displacement) due to fiber reinforcement, while M7G3 showed high elasticity (75% rebound). Acoustic testing demonstrated broadband sound absorption (up to 0.8 at 4000–6000 Hz) and frequency-dependent insulation (6–18 dB), attributed to pore-mediated wave scattering and viscous dissipation. This work has addressed the “sound-heat-force” performance trade-off issue existing in multi-functional composite materials, enabling the exploration of next-generation sustainable solutions for global energy conservation and reduction of noise pollution. It also paves the way for subsequent in-depth component proportion optimization to achieve balanced high-performance multi-functional materials.
