Measurement of microscopic strain distributions of CFRP laminates with fiber discontinuities by sampling moiré method

Strain Measurement of Composite Laminates Using Fiber Bragg Grating Sensors

Fiber Bragg grating(FBG) sensors, one of the fiber optic sensors(FOS), based on the wavelength division multiplexing(WDM) technology are ideally suitable for structural health monitoring of composite materials and structures. Proper monitoring of measurands in FBG sensor systems requires accurate measurement of the Bragg center wavelength, and the ability to track rapid shifts of the wavelength...

Strength and Modulus Degradation of CFRP Laminates from Fiber Misalignment

Fiber reinforced polymer (FRP) laminates are being used as external reinforcement for strengthening concrete members. The performance of unidirectional FRP laminates is highly dependent on fiber orientation with respect to applied load direction. In the case of fabrication by manual lay-up, it is possible to have fiber plies installed with improper orientation. In this project, the degradation ...

Impact Damage Detection of Toughened CFRP Laminates with Time Domain

Laminated Carbon Fiber Reinforced Polymer (CFRP) composites are very effective in weight saving in aeronautical structural components. For these laminated CFRP structures, it is, however, difficult to detect damage such as delamination, matrix cracks, and local fiber breakages caused by low velocity impact loading In the previous study in 2009, Time Domain Reflectometry (TDR) method was applied...
