Which standard can be used for determining the fiber volume fraction by comparing the electrical resistivity of the composite with the fibers? Correct Answer ASTM D3355

ASTM D3355 is a method of test for fiber content of unidirectional fiber-resin composites by electrical resistivity. This method is employed for the unidirectional composites containing electrically conductive fibers in a non-conductive matrix.
