Beschreibung
Interlaminar fracture toughness GIC were measured using double cantilever beam (DCB) test for mode- I using area method, compliance method, compliance calibration method and modified beam theories. The results showed that epoxy reinforced with random glass fiber has higher GIC (2834 J/m2) than that of epoxy reinforced with woven roving glass fiber (548 J/m2). The results of different types of mid plane layers show that the Interlaminar fracture toughness GIC for [R7//M1/M1//R7]is (3018 J/m2) which is higher than that of [M7//R1/R1//M7] is(354 J/m2). It was shown also that lay - up stacking sequences have an effect on the Interlaminar fracture toughness GIC. It was observed that GIC for [R/M//R1/R1//M/R]S is (1355 J/m2) which is higher than that [//M/R//]s is (260 J/m2). Nano and micro SiO2 particles were used as a third phase filler for woven roving glass fiber composites with (2,4,6,8,10) wt %. It was found that higher GIC was observed for nanocomposites as compared with microcomposites. The results shows that Young modulus for nanocomposites was higher than microcomposites, but flexural strength for microcomposites was higher.
