This document discusses fiber content and volume/weight fractions in composite materials. It introduces key concepts such as weight fraction, volume fraction, and how they relate through constituent densities. The maximum achievable fiber volume fraction of 91% is explained using hexagonal close packing of fibers. Typical fiber volume fractions are provided for different reinforcement forms like unidirectional, woven, and random mats....

It introduces key concepts such as weight fraction, volume fraction, and how they relate through constituent densities. The maximum achievable fiber volume fraction of 91% is explained using hexagonal close packing of fibers. Typical fiber volume fractions are provided for different reinforcement forms like unidirectional, woven, and random mats. Equations are presented to calculate laminate thickness from fiber content and volume fraction.
