Polymer volume fraction calculation
Did you know?
Fiber volume ratio is an important mathematical element in composite engineering. Fiber volume ratio, or fiber volume fraction, is the percentage of fiber volume in the entire volume of a fiber-reinforced composite material. When manufacturing polymer composites, fibers are impregnated with resin. The amount of resin to fiber ratio is calculated by the geometric organization of the fibers, which affects the amount of resin that can enter the composite. The impregnation aroun… Webby substituting an ‘ideal gas’ of Nmonomers in the pervaded volume of the polymer chain ˘r3.
