Certainly.
There are just so many scenario that can play out in composite construction.
What many don’t know is that the pretty outside layer does not necessarily indicate everything going on with composites. One bicycle frame I had built, the customer wanted it as “raw as possible”. I pulled a face and asked if he was CERTAIN. He said we was, UNTIL he saw it with no fillers, no cosmetic layer, just raw, unadulterated, hand-built composite, tubes, shells and assemblies glued together and carbon taped. He said, and I quote “it looks like a high school shop project”. My response was simple: “there is a LOT that goes on to purty up a piece of composite, let alone multiple pieces. He then accepted my answer and I had to strip all of the matte finish and hand-lay my finish. One positive? I DID develop an even cooler, abrasion-resistant outer finish from that process!
It is still technically one piece when components are fused together and finished with a finish layer; after all- none of the pieces could function on their own. Then only TRUE one-piece boot would be filament wound, which would be HORRENDOUSLY expensive, not to mention impractical!
