Abstract：Different orthogonal woven fabrics and angle-interlock woven fabrics have been fabricated by glass fi-ber, and composites was made through the vacuum-assisted molding( VARTM) process system. The impedance tube-Transfer Function Method is used to test the sound insulation property of those composites,then the impression of fiber volume fraction on the sound insulation property is explored. The result shows that:the sound insulation property of wov-en composites have an increase trend with the increasing of its fiber volume fraction. At the same time,the integrity of composite structures have some part in the sound insulation.
