CLT is in no way similar to the product InventWood is working on, besides that it uses the same base material, and I guess requiring some pressing. You can think of CLT as being like plywood, but for beams instead of for sheets.
That said, CLT has 2 major advantages over regular wood:
1. It is more dimensionally stable, it expands/contracts less and in a more uniform way.
2. It is cheaper at larger dimensions. I.e. 0.5m x 0.5m x 20m wooden beams would take decades to grow and even then not realiably, but you can just manufacture CLT beams with those dimensions easily out of <10yr old trees.
Those two advantages are not limiting factors for the construction of cars or airplanes, so CLT is not super relevant to them.
- toast0 1y agoDimensional stability isn't irrelevant to planes. Thermal cycling is inevitable when going from the ground to cruising altitude and back.
- kmacdough 1y agoCertainly would be better to laminate IF you're using wood. But it's still got a long road ahead. Aluminum still has a higher strength/weight ratio which is everything in aero. Also, I'm not finding any information on cyclic strain behavior. Dimensional stability is only part of that. Edit: There could be room for this in experimental aircraft. Once we tease out all the failure modes and properly characterize cyclic behaviorof course.
