摘      要：Microstructures of laminates produced by epoxy/carbon fibers with different fiber volume fraction were studied by analyzing the composite *** main result of the compaction of reinforcement is the flatting of bundle shape,the reducing of gap and the embedment of bundles among each *** void content outside the bundle decreased sharply during the compaction until it is less than that inside the bundle when the fiber volume fraction is over 60%.The resin flow velocity in the fiber tow is 102-104 times greater than the flow velocity out the fiber tow no matter the capillary pressure is taken into account or not.
