JOURNAL FREE ACCESSThe inter laminar stress distributions, obtained by three dimensional FEM, were discussed in order to explain the initial failure which was observed in the four point flexural test on the hybrid FRP made of unsaturated polyester resin reinforced by carbon and glass fibers. In three dimensional FEM, the thermal residual stresses due to the curing process were taken into consideration, too. It was found that the initial failure loads predicted by applying Hoffman's law well agreed with the experimental results.View full abstractDownload PDF (2169K) -

JOURNAL FREE ACCESSIn design of the composite structures for fatigue, a sufficient knowledge on fatigue properties of composites with a circular hole is of utmost importance. In this experimental research, the static strength and the various axial-fatigue properties of circular hole notched specimens of a carbon eight-harness-satin/epoxy laminate were studied, because this material has excellent characteristics among carbon fabric composites. The static tensile and compressive strength, the static compressive strength of specimens with a pin-inserted hole, the S-N relationship for the three representative stress ratios, the S-N relationship of the specimens with a pininserted hole by compressive fatigue tests, the effect of the loading frequency on the fatigue life, and the temperature increase of a specimen versus the loading frequency were investigated. Moreover, the static and the fatigue fracture surfaces and the fatigue damage process were observed visually and by using an electron microscope.View full abstractDownload PDF (4179K) -
