I work at a wind turbine blade testing facility and as a blade gets delivered we need to inspect it. Everything we do is self taught but we would like to actually get a training course (better if certified but it is mandatory) on composite defects and/or damage identification and/or classification. Ideally the outcome of the course should be some sample pictures and rules/guidelines for visually identify and classify defects on composites. We do not have ultrasound technique, at the moment we do coin tapping.
