Impact And Post Impact Behavior of Fabric Reinforced Geopolymer Composite

Original language description

Impact and post impact behavior of fabric reinforced geopolymer composites is investigated in this study.Carbon, E-glass and basalt fabrics are incorporated in the geopolymer matrix. The geopolymer composites are tested for impact resistance to an out-of-plane low velocity impact test, followed by post impactperformance testing using residual strength measurement on the sample. Impact properties such asimpact energy, energy absorption capacity, and damaged area of the composites were examined for fabricreinforced geopolymer composite samples. The drop weight impact tests were performed on compositesamples of 15 x 15 cm. The quality of the samples was examined using C-scan in ultrasonic vibrationmode and lCT before and after impact test. The post impact behavior of the composite samples wascharacterized using four point bending tests. Fiber orientation and alignment was observed using SEM.The results obtained showed that E-glass fabric reinforced composites show slightly better performancethan carbon reinforced composites. Especially the damaged area is smaller for E glass composites. Basaltfabric reinforced composites have low bending strength and very low impact resistance. The energyabsorption in E-glass is due to post-debond fiber sliding phenomena and in carbon fiber to fiber pullout from the composite. The smaller damaged area is attributed to the higher elastic energy absorptionof E-glass fibers. The residual strength of carbon and E-glass composites decreased in relation to the sizeof the visually damaged area, meaning that no invisible damage took place.
