| Abstract: | The effects of surface texture induced by secondary processing on the flexural properties of a graphite/epoxy laminate were evaluated. Test specimens were machined by three methods including the abrasive waterjet, circular diamond saw and shaper planer mounted with polycrystalline diamond tool inserts. Machined surface topography was evaluated by surface profilometry as well as scanning electron microscopy. Flexural strength and modulus were obtained from fourpoint flexure loading to failure and Weibull statistics were used to evaluate characteristic strength and modulus. Although the textures of the machined surface representative of each process were different, no difference in bulk strength of the graphite/epoxy laminate was noted under bending loads. |
