Would layering fabrics together with a clothes iron create a stronger fabric than a single heavier layer? Or would the resulting fabric lose too much flexibility? What would the result of layering two 190GSM fabrics together for a floor be vs a single 475 GSM floor?

Before building a skeena, I designed and built a packraft of my own which involved layering up two layers of approximately 250gsm fabric together. These were TPU coated on one side only, with the coated surfaces facing inwards. It did work OK except for a few wrinkles and as noted above, the laminated fabric is stiff.
I wasn’t overly happy with the final boat, hence building a skeena afterwards. 🙂 -
Yes and no… You can layer fabrics together to make something stronger, but you can’t iron directly onto TPU without making a mess, so at least one of the fabrics has to be coated on only one side. The woven fabric is less resistant to abrasion than the TPU (and soaks up water and dirt, etc.), so depending on the application, that may or may not be acceptable. Laminated fabrics will be stiffer, too.
