With growing interest in renewable resources for environmental purposes, natural fiber has been increasing for the development of biocomposites in several industries such as aerospace, automotive and, especially, construction sectors. Natural fibre-reinforced composites have received huge attention because of their lightweight, low-cost, mechanical, and biodegradable properties. This work aims to present the study of technical and functional sustainable textile structures for structural and aesthetical properties of textile-reinforced polymeric variable geometry panels for building facades. The combination of hemp natural textile structures as reinforcement, and thermoplastic polymeric films as a matrix, were explored to develop intermediate solutions bioprepregs and the subsequent multi-layered biocomposites. The biocomposites were developed using thermocompression. Additionally, innovative natural fabric-based laminated biocomposites have been studied and developed to face sheets for honeycomb sandwich panels, and textile-reinforced polymeric multi-layered panels. The focus was on aesthetics and structural performance considering the different textile constructions and sources, with differentiated textures and patterns, translucent polymeric films, and UV resistance. Test evaluation of impregnation, weight, thickness, air voids, tensile strength, flammability, and colorfastness to light were considered. The initial results showed great potential compared to existing commercial products and high-added value aesthetic properties.
