Macro and Micro Investigation of Internal Structure of Filament Wound Composite

Abstract:

Abstract: The characteristic of internal structure of filament wound composite is investigated by experiment in this article. Cylinders manufactured by two kinds of fiber, E-glass and carbon, and epoxy resin, are cut into several pieces along the winding direction. The sections of pieces are observed with optic microscope. The result shows that there are two kinds of structure in filament wound composite, laminate area and undulating area, consisting of interwoven fiber band in different directions. Undulating quantity is measured at a series of points along undulating fiber band; a linear model is adopted to model geometrical shape of undulation.
