This chapter addresses the environmental and energy challenges posed by the increasing production of composite materials, particularly those reinforced with carbon and glass fibres. Current recycling technologies focused on fibre recovery, such as thermal and chemical methods, now enable the production of fibres suitable for reintegration into the value chain. The chapter details adapted textile technologies for processing these recycled fibres, covering methods from non-woven fabric production to the newest manufacturing technology of yarns and unidirectional tapes. Technologies such as carding and yarn formation are analyzed, highlighting the need for hybridization with virgin materials to enhance the mechanical properties of the final products. While current advances do not yet match the performance of virgin materials, ongoing research continues to optimize these processes, paving the way for the industrialization of more sustainable composites, with applications ranging from lightweight structures to sectors with higher mechanical requirements.

Continuous fiber-reinforced thermoplastic composites are emerging as an efficient structural alternative to traditional thermoset materials, thanks to their recyclability, good impact resistance, and suitability for continuous processing. In this work, a manufacturing system was developed based on the thermoplastic pultrusion of unidirectional polypropylene (PP) and carbon fiber (CF) tapes, followed by hot compression molding. This approach enables the production of structural profiles with high fiber alignment and good consolidation. Experimental characterization included tensile, flexural, and impact tests to assess the structural applicability of the manufactured profiles. The results demonstrate a balanced combination of stiffness, mechanical strength, and impact performance, confirming the potential of this system for functional applications in sectors such as mobility or infrastructure, where lightweight, efficient processing, and sustainability are key requirements.
