Sustainable Non-Flammable Hybrid Composites with Ocean-Recycled Polyamide 6

This dataset details the properties of hybrid composites made from ocean-recycled polyamide 6 reinforced with silane-treated basalt fiber and lignin-derived biocarbon. The composites were developed for automotive and electric vehicle applications, achieving a UL-94 V-0 flame retardancy rating and a 179% increase in tensile modulus compared to neat polyamide 6.

Use Cases

• Analyze the relationship between biocarbon weight percentage (e.g., 10 wt%) and mechanical properties like tensile modulus and flexural modulus.
• Model the impact of silane-treated basalt fiber and lignin biocarbon on thermal properties such as heat deflection temperature and coefficient of linear thermal expansion.
• Investigate the correlation between composite formulation (including recycled PA 6 content) and flammability performance metrics like UL-94 rating and horizontal burning rate.
• Study the effect of hybrid reinforcement on processability indicators such as melt flow index values.

Strengths

• Composites achieved a UL-94 V-0 flame retardancy rating and zero horizontal burning rate.
• Optimized composites showed a 179% increase in tensile modulus and a 194% increase in flexural modulus compared to neat PA 6.
• The hybrid composites demonstrated a heat deflection temperature above 200 °C and a 53% reduction in the coefficient of linear thermal expansion.

Limitations

• The dataset scope is limited to specific material formulations described in the research, not a broad survey of composite materials.
• Sample data and raw experimental measurements are unavailable, limiting direct analysis of variance or distribution.
• The dataset is derived from a single research study, which may limit generalizability to other manufacturing conditions or material sources.
