That's an approach explored by many it seems, and success on this front would certainly have to be considered a risk of investment in novel transport solutions.

That's an approach explored by many it seems, and success on this front would certainly have to be considered a risk of investment in novel transport solutions. As far as I know, factories heat-treat (and pressure-treat) those composites in one go, in a huge oven enclosing the entire blade. On-site manufacture would either require those huge heat treatment units built locally or somehow made transportable, or a process that does without. It might be a bit of a chicken/egg situation, the materials science required to do without the full-size oven not being worthwhile without a transportable implementation of all the assembly and layup arrangement that would have to be done before, and the logistics not happening without a solution on the materials side.
