Nylon, Xynole, Cordura, Innegra, all have higher elongation and require a resin with higher elongation. Xynole was the origin of 2020 resin which allowed that material to work. So it was also the origin of the multi modulus resin system. But any of these synthetics are a good way to make bullet proof boards simply. BTW my FL factory manger Sam Barker, a former pro, still rides only Xynole boards today. Insists they ride better.
Also, gotta be careful with the synthetics on resin take up. They can drink resin. Do a really dry laminate wait for it to tack and then mix up 3 ounces and do a cheater. Weight this way is reasonable. Bagging is an even better.
Elasticity with tensile strength. Will it stretch and snap, or stretch and not break. Nylon 6,6 is not weaker than epoxy alone. Anyone who thinks it is, hasn’t tested it. But I’m beating a dead horse now. It is your board to make any way you like. Enjoy.
Haavard in Europe xynol is called diolen. I find it’s a bit hard to find with great conditions in France. May be you’ll be lucky. I know some guys use it in UK. It’s a pet fabric, sightly heavier and stiff than nylon (wich was from same chemical family) but with 2 main advantages: stick better with resin and stable to uv and humidity. Often use in fiber kayak to prevent full open dings, it craks but not open brutally so the boat don’t take water too fast. A cheap alternative to kevlar.
Greg,
Any suggestions for a layup schedule with 2.2oz innegra? I still have some on hand that I want to bag over a stringerless 2# blank.
