Performance of pultruded fibre reinforced composite materials in ventilated façade components: experimental testing and assessment methodology

The buildings and construction sectors account for over one-third of global final energy consumption and nearly 40% of total CO₂ emissions. Addressing this challenge requires innovative building envelope solutions to enhance energy efficiency and sustainability. This study explores the potential of pultruded Fiber-Reinforced Composite materials in ventilated façade systems, emphasizing their mechanical, thermal, fire, and environmental performance [1]. The novelty of this research lies in the development and validation of an advanced testing protocol, integrating experimental analysis and numerical simulations to evaluate key performance indicators such as mechanical strength, thermal transmittance, durability, and weather resistance. A key contribution of this work is the assessment of Fiber-Reinforced Composite-based façade components in reducing thermal bridging and improving energy efficiency. The research follows a structured methodology, starting with a review of existing literature, implementing and refining current testing protocols with a new approach, and calibrating simulation models based on laboratory analysis. Additionally, the study introduces new evaluation criteria to enhance the replicability of results under diverse boundary conditions [2]. The fabrication process is also examined, providing insights into its influence on the final material properties and establishing guidelines for improving manufacturing standards. Furthermore, an environmental impact assessment highlights the recyclability potential of FRC materials, reinforcing their contribution to circular economy principles [3]. The findings offer a comprehensive framework for designers and engineers to optimize façade performance [4] while ensuring compliance with stringent regulatory requirements.
