Comparative study reveals that autoclave thermoforming and hot-press moulding affect performance in green composites, suggesting production optimization based on sustainability goals.
The demand for sustainable and efficient manufacturing of lightweight polymer composite parts is driving the adoption of thermoplastic-based composites reinforced with natural fibres. This study explores two distinct manufacturing processes (autoclave thermoforming and hot-press moulding) to produce green composites from flax fibre woven fabric and polypropylene prepregs. The thermoforming process in autoclave offers precise pressure and temperature control, ensuring high-quality consolidation and fibre impregnation. Conversely, hot-press moulding allows for faster cycle times and increased production efficiency due to its direct compression approach. A comparative analysis of the two methods highlights differences in fibre-matrix adhesion, mechanical properties, and process repeatability. The results demonstrate that while both methods achieve high-performance eco-friendly composites, the choice of process can be optimized based on production rate and sustainability goals.
