Using Epoxy resins to saturate wood and give it desired engineering characteristics has been done for decades. Before Epoxy, resorcinol glues were used to make airplane wings and propellors, and of-course boats. Some of the early wind power propellors were made of wood veneers as they were lighter and their performance could be very accurately predicted. Not sure flexibility is a desirable characteristic in a bicycle frame though. Wood saturated with epoxy is probably as dimensionally stable as any other material in regards to environmental changes. The difficulty is doing it the same every time.

Rob, while your title calls it a Material of the Future (I get it, spoken tongue in cheek) there was one line I specifically noted which guarantees this initiative will never launch as tomorrow's material of choice: "Each frame takes hundreds of hours to build". This is a beautiful hobbyist project, and they do look like a fun garage project; but I'm missing the point of why it's being developed at a University.

Given the right wood, adhesives and coatings, there's no reason to be sceptical about wooden bike frames. We've been building wood-framed (and some plywood-skinned) aircraft for over a century now, with great success. A comparable engineering challenge, perhaps, with weight, strength and complexity well within our abilities. Wooden boats have perhaps more latitude with weight, but greater requirement for the right water-resistant coatings and adhesives.

Agreed, it's a beautiful material, but I worry about moisture and then the lack of it.  This Winter has been so awful that I have three guitars in the shop for cracks.  Two of them are over forty years old and have never had humidty problems before.

 

I bought a humidifier.

Wooden bike frames have been very popular for a while on the west coast of the U.S.  I haven't heard of any problems with weather or moisture.  An epoxy resin can be used, just as with boats.

I wish the article included some of the existing brands that are also using this vintage material for today's bikes.  The first bicycles were made of wood too.

Interesting idea Rob. These bikes would definitely dampen the road vibrations and look beautiful on the tracks, but what worries me is the deterioration of wood. We all know it is a hygroscopic material and it will be affected by vapors and other environmental factors. Will the design be able to cater these environmental influences? Because if not, these bicycle frames could be seriously damaged with absorption of moisture and deformation of wood.
