Carbon Fiber Reinforced Plastic (CFRP) laminate composites are often tailored to provide stiffness in particular directions to optimize performance. The standard ultrasonic inspection however uses a cross ply measurement of acoustic attenuation to assess the consolidation quality of the CFRP. While this is useful for porosity, delamination or inclusion detection, it does not address a primary interest in the use of CFRP. A more appropriate measure of the quality of the laminate would be the determination of the in-plane characteristics to evaluate the desired directional stiffness of the product. This paper describes an in-plane ultrasound method using insertion and receiving sensors spaced known distances apart on the surface of the CFRP structure and in a desired directional orientation for evaluation. The time and distance of the transmission of the head wave from the insertion to the sensing allows a velocity calculation. This method is demonstrated using laser generated ultrasound and a pin receiver....
