Case Study

Chopped Carbon Fiber Reinforced Epoxy Composites

Ozsoy, N., M. Ozsoy, et al. Acta Physica Polonica A, 2016, 130(1), 297-299.

Four different weight fractions (0%, 6%, 8%, 10%) of chopped carbon fiber were added as reinforcement materials of composite materials, and the tensile, bending, impact and hardness properties of reinforced epoxy composites were experimentally studied.
Preparation of samples and effect of chopped carbon fiber
· The materials used in this study are chopped carbon fiber as reinforcement material and epoxy resin as matrix. Epoxy resin and curing agent (HGS L285) were mixed in a mass ratio of 100/40, after which the reinforcement material was added to the mixture and mixed. The mixture was poured into the polished mold. The mold was closed under pressure to avoid bubbles in the composite and heated to 60°C for one hour. After that, the composite was cured in the mold at room temperature for 24 hours. When the composite was hardened, it was taken out of the mold.
· The mechanical properties of the composites were influenced by the quantity of reinforcement used. The findings indicate that incorporating chopped carbon did not significantly improve tensile strength. The highest tensile strength was recorded in composites containing 8% carbon fiber. As the proportion of chopped carbon fiber rose to 8%, both bending and impact strengths also improved. However, at a reinforcement level of 10%, the matrix could not sufficiently hold the composite together, leading to a decline in strength. Additionally, the hardness of the composites increased with a higher content of chopped carbon fiber.

Chopped Carbon Fibers for Concrete Reinforcement

Muley, Prashant, et al. Int. J. Sci. Eng. Appl. Sci, 2015, 1, 2395-3470.

This study investigated the effect of chopped carbon fibers on the mechanical properties of concrete (compressive strength, splitting tensile strength, and flexural strength) using fibers with different volume fractions. Carbon fibers are materials consisting of fibers with a diameter of about 5-10 microns.
Evaluation methods and results
· To assess the impact of fiber volume fraction on the mechanical properties of concrete, five batches were tested, featuring fiber content levels of 0%, 0.25%, 0.5%, 0.75%, and 1.0%.
· With increasing fiber content, the workability of concrete decreased significantly, which was evaluated by standard slump test.
· The compressive strength test results showed that the use of fibers in concrete improves strength and contributes to early strength gain.
· The strength of the specimens containing fibers increased significantly over that of the specimens without fibers in flexural and splitting tensile tests.
· The flexural test results showed that the concrete containing fibers did not show brittle failure after the first crack and the concrete could withstand further loads after the first crack, indicating an increase in the ductility of the concrete.
