  1. Densification of wood has been done over the years and I have used epoxy and vinyl ester to do various things with wood as well. Phenolics are mentioned and these are good because they are very thin and infuse well. The process will improve the strength and stiffness of wood considerably. Easily being stronger than mild steel and low grade titaniums which are not very strong anyway. But these things are unlikely to get to high strength steel and Ti grades say around 1000Mpa UTS. So you grab your piece of timber and place it in a vacuum bag. Place a suitable infusion mesh (and plumbing etc for a normal infusion) over the end grain and use your resin of choice. Whatever the weight of the timber is be prepared with about the same weight of resin or more. MDF also can be filled with resin as well just sand off it’s hard skin before you try. Pull down the vacuum to below the saturated water vapour pressure at your site and wait until the vacuum stabilises if you have digital absolute vac gauge this helps to check you have removed all the free moisture from the timber. This is very important may take 2 or 3 hrs, other wise the results will be poor due to moisture contamination. Once the vacuum soak is complete turn on the resin taps and the timber will fill with resin. It will be twice as heavy, very stiff and very strong depending on the resin you use. Timber is designed to transport water so it transports thin resin very easily. Cheers Peter S

  2. Kind of reminds me of ammonia infusion to make wood ply to any shape. Kind of makes me want to look into additives that are ammonia soluble to see if I could make it harder.

    Wouldn’t use this in a boat hull bit for a mast well no dry rot.
