HYBRID FRP-TIMBER BUILDING SYSTEM AND MATERIAL SYSTEM DEVELOPMENT FOR LONG-SPAN STRUCTURES AND EXISTING BUILDING STOCK EXTENSIONS
Conceived as the extension project of the first phase RP11, this project will address the fundamental research challenges that were encountered during the first stage of development of novel coreless filament wound fibre reinforced polymer (FRP) building systems. Three main challenges were identified and formalized: the weakness of such systems in creating continuous surfaces and therefore, to properly enclose a space, the relatively long production time of the construction elements and, ultimately, the heavy environmental footprint of the materials predominantly used. One of the main consequences of the filigree or lattice-like configuration of coreless filament wound fibre elements, is their inherent inability to create continuous surfaces and therefore to define hermetic architectural spaces. This project will focus on solutions addressing this shortcoming by combining the lattice-arranged filaments with two-dimensional timber plates by means of mechanical fasteners. Design space explorations for such FRP-timber hybrid components, catering to their architectural function while at the same time enhancing their structural capabilities with timber plates redistributing live loads and fibres providing structural depth to the system will be carried out in this project. From a fabrication standpoint, the timber plates can potentially become an integral part of the winding frame, reducing the complexity in the overall fabrication setup. This reduction in complexity will be the first step towards the goal of abating the overall production time. Such goal will also be pursued by employing two robots to simultaneously wind one element. Central aspect of this research project will then be the exploration of the design space for FRP-timber hybrid elements enabled by the augmentation of the fabrication platform. To address the issue of the heavy environmental footprint of materials so far used for coreless filament wound elements, this project will investigate alternative combinations of fibre (natural, renewable or semisynthetic) and resin systems on the base of the preliminary studies carried out during the first phase of RP11. The goal of this project will be to expand options of materials suitable for CFW, as well as to define sensible fibre-resin material combinations for specific building elements geometries and configurations.
