Failure Analysis of Carbon Fiber Reinforced Polymer (CFRP) Bridge Using Composite Material Failure Theories

Article Preview

Portable bridges are very important for maintaining mobility in the aftermath of natural disaster or in the battlefield. This requirement has lead to the needs for light-weight bridging system for ease in launching, retracting, transporting, and storing. In this research, a foldable bridge with three sections of beam connected together using the hinges connection has been designed and analyzed. The bridge is constructed using sandwich Carbon Fiber Reinforced Polymer (CFRP) which consists of CFRP and Aluminum Honeycomb, as the skin and core, respectively. The uses of materials are expected will reduce the total weight of bridge without decreasing of overall performance. Failure theories of composite material such as Maximum Stress, Maximum Strain, Tsai-Wu and Tsai-Hill failure theories were selected to generate an allowable strength graph. From the graph, can be seen that, the material stresses are in the allowable stress-strain ranges, therefore, the bridge is capable of carrying the design load with sufficient safety factor.
