Fibrous Joints for Lightweight Segmented Timber Shells
-
Dominga Garufi
Abstract -
With fibrous joints for lightweight segmented timber shells we introduce novel techniques for three-dimensional placement and curing of CFRP-Tows within prefabricated plywood plates to create differentiated fibrous bending-resistant timber plate joints. Density, orientation, and position of the fibrous joints can be informed by the calculated local principal tensile forces and dihedral plate angles between 90° and 270° can be achieved, which allows for the gradual integration of various functional and structural aspects into segmented shell structures. After the CFRP tows are placed inside the wood, the matrix can be consolidated in situ via controlled application of electric current without bonding the fibers to the wood. This opens up the possibility of mobile on-site fibrous joining of large-scale structures, as CFRP tows can be cured independently of autoclave sizes. The joints’ structural capacity is based on the form stability of the CFRP loops rather than any chemical interface between fibers and plywood plates. This allows the two materials to be separated at the end of the structure’s lifetime.
