You should be specific about the fiber/matrix ratio. Is your plot for weight% or volume%? Weight% is more useful for the builder because the correct amount of resin needed can be estimated from the weight of the cloth. However, in most situations using hand layup and light plain weave cloth - such as in strip building - excellent results can be obtained using a squeege to spread resin until the cloth texture is visible, yet the cloth is fully wet.
