Research on reinforcing airplane structures while reducing their weight by employing sustainable materials is currently challenging. In this study, damage mechanisms, mechanical characteristics, and failure behavior of laminates made of plain-woven glass fiber/epoxy and Glass Fiber Reinforced Polymer (GFRP) with sea shell filler under low-velocity impact static loading conditions are experimentally investigated. The bi-directional GFRP type E-glass laminates with 10 plies and a total thickness of 3.35mm are created by hand lay-up process using an epoxy matrix. Comparing GFRP with an effective ratio of sea shell filler of 5% under various impact loading, composites are characterized in accordance with ASTM standards to assess the progressive damage and failure of GFRP composite. The findings of the experiment indicate that GFRP with seashell filler composites outperforms GFRP composites in terms of impact strength, outstanding flexural strength, and tensile strength. The findings show that adding seashell filler to GFRP increased the composite's ability to sustain various impact loads. The sample with seashell infill has a drop weight impact that is 25.26% lower than GFRP. Moreover, the flexural test demonstrated a 59.6% increase in bending over GFRP. Seashell filler outperformed GFRP in the longitudinal strength test by 33.12%, according to the results of the tensile test. Finally, the compression after impact test (CAI) manifested a remarkable increase in transverse strength by 78.23%.

The improvement in social production efficiency demands increasingly faster mechanical operation speeds. However, under high‐speed friction conditions, the frictional heat generated by nylon 6 (PA6) components is difficult to dissipate efficiently, leading to severe wear and subsequently threatening the safe operation of the equipment. In this work, interconnected expanded graphite/stearic acid (EG/SA) networks in PA6 composites were constructed to achieve fast frictional heat dissipation and self‐lubricating properties by a simple hot‐pressing method. The synergistic lubrication of EG and SA results in PA6 composites with a low coefficient of friction (COF) of 0.12, a 74.5% reduction compared to pure PA6. The low COF reduces the generation of frictional heat, while the conduction and absorption of frictional heat by the EG/SA network accelerates the dissipation of frictional heat, ultimately lowering the contact temperature from 106.9°C to 40.6°C. The specific wear rate of the PA6 composite is as low as 1.7 × 10−5 mm3 N−1 m−1, which is 90.1% lower than that of pure PA6. This study provides a new solution for the rapid dissipation of frictional heat in polymer composites under harsh operating conditions and broadens the application range of wear‐resistant polymer composites.Highlights Expanded graphite (EG) prevents stearic acid from leaking through adsorption. The interconnected EG network transfers frictional heat to stearic acid. The phase transition of stearic acid can absorb heat and promote lubrication. The low COF and high heat dissipation make PA6 composites highly wear‐resistant.
