Experimental Characterization of Microscopic Damage Initiation and Growth in Quasi-Isotropic CFRP Laminates.

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...

Ultrasonic NDE Techniques for Impact Damage Inspection on CFRP Laminates

This study investigates the different types of ultrasonic inspection, when applied to assess the impact damage in Carbon Fiber Reinforced Plastic CFRP laminates. The study surveys the two most used ultrasonic testing approaches first; namely the pulse-echo and the through-transmission modes. Then, the manuscript discusses and analyzes the enhanced ultrasonic testing methods that use the polar s...

Electromagnetic Shielding Property of Cfrp Composite Laminates

Observation of Damage Growth in Compressively Loaded Laminates

An experimental program to determine t ie pi-enomenological aspects of composite-panel failure under simultaneous compressive n-plane loading and low-velocity transverse impact [C-75 m/s (0-250 ftls)] is described. Highspeed photograohy coupled with the shadow-moire techniq~e is usec to record the phenomenon of failure propagatior. The informat on gained from these records, supplemented by plat...
