Mode II delamination of carbon-glass fiber/epoxy hybrid composite under fatigue loading

In this paper, the impact behavior of Kevlar/glass fiber hybrid composite laminates was investigated by performing the drop weight impact test (ASTM D7136). Composite laminates were fabricated using vacuum bagging process with an epoxy matrix reinforced with twill Kevlar woven fiber and plain glass woven fiber. Four different types of composite laminates with different ratios of Kevlar to glass fiber (0:100, 20:80, 50:50 and 100:0) were manufactured. The effect of Kevlar/glass fiber content on the impact damage behavior was studied at 43J nominal impact energy. Results indicated that hybridization of Kevlar fiber to glass fiber improved the load carrying capability, energy absorbed and damage degree of composite laminates with a slight reduction in deflection. These results were further supported through the damage pattern analysis, depth of penetration and X-ray evaluation tests. Based on literature work, studies that have been done to investigate the impact behaviour of woven Kevlar/glass fiber hybrid composite laminates are very limited. Therefore, this research concentrates on the effect of Kevlar on the impact resistance properties of woven glass fibre reinforced polymer composites.

In this research a study of the effect of quality, sequential and directional layers for three types of fibers are:(Kevlar fibers-49 woven roving and E- glass fiber woven roving and random) on the fatigue property using epoxy as matrix. The test specimens were prepared by hand lay-up method the epoxy resin used as a matrix type (Quick mast 105) in prepared material composit . Sinusoidal wave which is formed of variable stress amplitudes at 15 Hz cycles was employed in the fatigue test ( 10 mm )and (15mm) value 0f deflection arrival to numbers of cycle failure limit, by rotary bending method by ( S-N) curves this curves has been determined ( life , limit and fatigue strength) of composite . The results show us the reinforcement has important act to increased resistance to the fatigue compared with specimens have non reinforcement this side the specimens reinforcement of glass fiber have resistance to fatigue and fatigue life better than the specimens reinforcement of Kevlar fiber . According to hybrid composite sample fatigue test results showed that the sample which reinforced (Kevlar - regular glass – Kevlar) has a best results which showed stress carrying the most powerful and longer fatigue life with more than (1.3 ×10 6) cycle from other hybrids , while the sample with the sample with three Kevlar reinforced layers have less resistant to fatigue

Novel Material

Recent years, Polymer matrix hybrid composites have a greater attention in industry and research due to growing demand for versatile applications. The present work focused on the development of epoxy based hybrid nanocomposites. Nanoclay is another novel material that is widely used in the research. In this investigation, nanoclay dispersed hybrid composite materials has been studied for mechanical and wear behavior. Glass fiber and banana fiber combined epoxy laminates (EGB) were reinforced with nanoclay at different weight fractions of 2%, 4%, 6%, and 8% using compression moulding. The enhanced properties of the nanoclay hybrid composites were analyzed with other specimens. Water absorption character study was also conducted. Morphological study was performed using Scanning Electron Microscope. It was observed that an optimum result attained with 4 wt% nanoclay reinforced composite with an increase in tensile strength of 8.62%, flexural strength of 30.19%, and impact strength of 48.15% when compared to EGB. Further the wear resistance of 4 wt% nanoclay hybrid composite showed an increase of 19.4% than the EGB composite.
