Fibre Volume Fraction (FVF)

ASTM D2584

Standard Test Method for Ignition Loss of Cured Reinforced Resins.

Why the need of FVF?

Fibre Volume Fraction (FVF) is a fundamental parameter in composite material science that directly impacts the performance and properties of fiber-reinforced composites. Understanding and controlling FVF is essential for the optimal design and manufacturing of composite materials.
FVF is essential for understanding and predicting the mechanical properties of the composite material, such as stiffness, strength, and thermal properties. This method is applied routinely on Glass fibre based laminates as well as Carbon fibre based laminates at AeroNordic.

Methods of Determination

Several methods can be used to determine the FVF, including:

Density Method: The densities of the composite, fiber, and matrix materials are used in combination with mass measurements to calculate the FVF.

Resin Burn-off: The composite is heated to burn off the resin, and the residual fibers are weighed.
