While some of you may have just lost interest because you think math is too difficult, I can assure you that this math requires nothing more than some basic multiplication, addition, and division. Let’s get to it. Here is the equation we’ll use to calculate the average thickness for a single layer of laminate: In this equation: • tL represents the total composite laminate thickness.• WF represents the aerial weight of the woven or knit reinforcement fabric you are using in your composite laminate.• PF represents the density of the reinforcement fibers.• PR represents the density of the resin system you are using. In this instance, the…
