摘要：

Significant spatial variation in void content and morphology might exist for resin transfer molded E-glass/epoxy composites. These variations seem to correlate well with the local velocity of the fluid front during filling. The slower moving fluid front traps less and more circular voids, whereas the voids might be sheared into more elliptical and irregular shapes near the parts' surface and inlet gate.
