Beschreibung
Zusammenfassung:The present invention discloses a testing apparatus for testing air permeability on thickness direction of a plastic matrix, comprising: a mold at least comprising a cavity and a cover plate, a loading device, a temperature control device, a vacuum suction device, and a flow detection element, wherein the cover plate has a receiving through hole in which an upper permeable sheet and a lower permeable sheet are received, the loading device being adapted to press the upper permeable sheet, a test sample to be tested being laid flatly between the upper permeable sheet and the lower permeable sheet; an air inlet and an air outlet being arranged on the cavity in an up-down direction of the cavity corresponding to the upper permeable sheet and the lower permeable sheet, respectively. The air inlet is communicated with the flow detection element and the air outlet is communicated with the vacuum suction device. The present invention can be applied to achieve accurate test of air permeability of the prepreg plastic matrix in the thickness direction under different pressure and temperature conditions.
