Laminate Calculators for Knit Reinforcements
Below you will find laminate calculators for some of our common knit reinforcements. Knit reinforcements consist of fiberglass, carbon fiber, or kevlar yarns laid down in the same direction on each plane, for example the first layer of a double bias has all of its yarns laid in plane at 45 degrees, the next layer is laid on top of that at -45 degrees, and then the two layers are stitched together. Straight in plane yarns provide better mechanical properties, increase the drapability of the fabric (in the case of double bias knits), or increase the porosity of the fabric (in the case of 0/90 Knits), and provide the ability to tailor material properties to where you need them.
Please keep in mind that calculators do not have a factor for wastage as it can vary widely due to a number of factors.
