Study of Carbon Fiber Reinforced Polymer Composite Layer Structures Subjected to Three-Point Bending

Year: 2024

Type: article

Abstract: The development of new composite and structural materials in various areas of industry has led to an ever-growing interest in research results regarding the applications of these materials.Combining these materials allows for the modification of the strength characteristics of structures and components manufactured from them.The article presents the results of bending test of carbon fibre reinforced polymers (CFRP) strips bonded with a two-component epoxy adhesive.Additionally, the reinforcement effect resulting from gluing composite strips (multilayer reinforcement) was compared with shortened strips.The positive and negative influences of shortening strips unidirectionally reinforced with long fibre have been discussed.Differences in the stiffness of the tested belt systems indicate that adding another belt increases the load capacity by approximately 100% of the bending force compared to the previous test of fixed-length belts.TSP tapes also show an increase in the ability to transfer the bending force by gluing subsequent strips, but not necessarily along the entire length, as shown in tests.Simulation tests showed smaller displacement compared to physical samples.The smallest differences between measurements and simulation results were recorded for two-layer configurations, while the largest differences were observed for four-layer strips.
