Bended Wood Panels

Selected work in open call section, Patternitecture event, Tehran, 2019

 

May 13 & August 10, 2018

Nature is the most important source of inspiration for all types of designing. Nature hates straight lines, but it is an opulent source of curves and flexibilities. Bended wood Panel is a great experience in the field of material properties. Wood is not flexible by itself, but there are several methods for making it flexible. Among different methods of bending, like a steam box, laminating and so on, we chose to bend with kerfing patterns due to its computational nature and the effect of geometry in the process.

Bended wood panel is an experimental fabrication experiment. The main purpose of this project was to study the bending capacity of wooden pieces. Among different methods for bending wood pieces, the Kerfing patterns were selected due to their computational features. To reach this goal, an experiment was needed and for this experiment, we devised a specific device that could measure the bending by two different factors. The two factors were the span and height.

 

Bending Test
Different patterns with varies scales were applied to a similar wood piece. For each and individual one, the experiment was exerted and all the results were recorded. Every piece of wood was placed in the device and then it would be pressed till the first and last part of the wood reach each other or otherwise the wood piece broken into its parts. The result was a chart with many interesting findings.

This test had remarkable results. As the congestion of patterns raise the flexibility of the wood will increase and also there are some patterns that make the wood extremely fragile like hexagonal patterns. If the patterns expand in two directions and have cut line in both sides the wood will flexible in two sides and create a double curvature surface. Moreover, if the pattern develops in the surface in just one direction and has cut lines in one direction, the wood will bend in one side only. The other thing that is worth to mention is that these methods can grant some tension characteristics to the material. We saw that the size of the pieces increases a little. We obtain some test results and put them in a chart and see the impact of the pattern and the congestion of that in a piece of wood.

Experimental Workshop 3 Days
The first step of the workshop was educating the participants in order to be able to design curved surfaces in Grasshopper3D and Rhino.

Then, every team supposed to fabricate their design with Cardboards.
Lastly, we invited several of our professors to rate the outcomes and then we chose one of them for the final fabrication.
For the last part of the 3 Days workshop, we asked every group to design and fabricate one small panel with kerfing patterns and those panels were spectacularly amazing.

Fabrication Day

1-Laser Cutting of the structure

2-Laser cutting 120 pieces of wood with kerfing patterns

3- Assembly

The outcome was a panel with about 120 wood pieces. All of them were remarkably flexible and the whole pattern was convergent towards its centre.
This panel was selected by the jury of Patternitecture event in Tehran, Iran in open call section in December 2019.
