Unusual Tensile Behavior of a Soft Epoxy/Carbon Fiber Composite (English)
The effect of strain rate on the mechanical behavior of pure flexible epoxy and its carbon fiber composite was investigated. The carbon fiber composite was made with variation in the number of plies and degree of orientation. Samples of cured epoxy and composites were tested at various strain rates (800mm/min, 100mm/min and 1mm/min). Analysis of the results showed unusual behavior in the fact that the fracture strain increased with an increase in strain rate. In order to investigate further, FTIR and NMR spectroscopy was carried out on the samples. Also, a swelling experiment was done in order to determine the swelling ratio of the polymer composite. The fracture morphology of the specimens was studied using SEM.
