Thermoplastic composites are gaining attention for their ability to support a circular economy, shifting away from traditional cost-driven design. Unlike thermoset composites, commonly used in automotive and aerospace sectors, thermoplastic composites offer recyclability, promoting environmental and economic sustainability. Adhesive bonding in thermoplastic composites provides even stress distribution, maintaining structural integrity and reducing delamination risks, which is crucial for lightweight design in transport and renewable energy applications. Optimising adhesive bonded joints is essential to improve structural integrity, efficiency and sustainability. This involves balancing technical, economic and environmental factors, with surface preparation, plasma treatment in particular, playing a key role.This paper provides a comprehensive techno-economic-environmental comparison of adhesive bonded joints. The study integrates cost-effectiveness, production efficiency and environmental impact assessments to guide informed decision-making. The methodology includes preparing substrates with low-pressure plasma surface treatments, forming adhesive-bonded joints with different adhesives, and optimising process parameters using Response Surface Methodology (RSM). A Life Cycle Assessment (LCA) on optimised scenarios enhances Tensile Shear Strength (TSS). The study concludes with a comprehensive comparison, offering insights for resilient, efficient and sustainable engineering solutions. |
