Major Inspection Projects
Midas-NDT have received orders, from two separate companies, for the inspection of a large quantity of composite coupons. Composite coupons are manufactured and individually impacted at different forces to identify the effect of impact on aerospace structures.
As can be seen in the illustrations above, the surface of the coupon shows no evidence of damage from the impact. The c-scan image as well as showing the general structure of the component shows major damage in the impacted area (ringed in red on the component picture). This is a phenomenon known as BVID (Barely Visible Impact Damage) and it is key to component design to understand the affects of differing forces of impact on the internal structure of components.
