Procedure

The density of the fibers was determined according to Equation (1). From the fibers’ density, the fiber volume fractions were obtained at each fiber content following Equation (2).

where $wm$ and $wF$ are matrix and fiber weight fractions, respectively; $ρc$ and $ρm$ are the density of the composite and matrix, respectively, both measured employing a pycnometer; and the fiber density and fiber volume fraction are represented by $ρF$ and $VF$, respectively.
