Abstract Due to an increasing demand for composite materials, especially in the aeronautic field, this research work will focus on finding an average attenuation range and a standard deviation of attenuation range in which it will enable us to qualify as a "good" standard quality based on a comparison with mechanical properties such as fracture toughness. The study will be based on a series of data obtained from an ultrasonic inspection (pulse-echo mode) on laminates manufactured by RTM process (resin transfer molding) which after these steps will be prepared for double cantilever beam static test in mode I (opening mode). The resulting data will be processed and compared in order to establish a relationship between ultrasonic parameters and fracture toughness properties. | |
