As a carpenter, the first thing I wonder about is dimensional stability. Wood expands and contracts with humidity and temperature, quite a lot more than people expect. How is that going to work on a precise object like a phone screen, or as a partially load bearing window? Not insurmountable, but very tricky stuff. In precise woodworking (fine furniture, marquetry, etc) dealing with wood movement is the main challenge and we have hundreds of years of work on the problem.
- valine 3y agoThink of it more like wood fiber reenforced epoxy. It will behave more like epoxy for most applications.
- etrautmann 3y agoPresumably it would behave like stabilized wood where it cant absorb much moisture since the epoxy has replaced internal voids?
- munk-a 3y agoYea - part of the process of epoxying the wood for translucence is fully drying it out so that those same pores and gaps can instead absorb the alternative compound.
- sheepshear 3y agoIt would be determined mostly by the dimensional stability of the polymer they're injecting.
- NegativeLatency 3y agoI suspect as with wood you'd see more expansion perpendicular to the grain compared to parallel to the grain because of the effect of the cellulose fibers all running in the same direction.
- sheepshear 3y agoYeah, that part wouldn't change.
- calamari4065 3y agoThose changes in wood are driven mostly by the fibers absorbing or desorbing water. Think of it as pressure treated lumber, except with epoxy. The structure of the wood becomes encased in epoxy and can't move at all. Then your dimensional tolerance is down to that of the epoxy, which is generally pretty good.
