    Abstract

    The scanning electron microscope (SEM) was used to characterize the degradation of the outermost layers of carbon/bismaleimide laminates as the result of exposure to a natural tropical environment. The surface that was exposed to the sun for 4000 h suffered complete degradation of the bismaleimide matrix to a shallow depth.

    SEM fractography showed little difference in the fracture appearance of the fibers in a carbon/bismaleimide laminate, which displayed considerable fiber pullout, compared to fibers in a carbon/epoxy laminate, which displayed little pullout.
