Delamination occurs when layers of the composite separate, weakening the material. This defect is often caused by impact damage, manufacturing errors, or fatigue. Since delamination is not always visible on the surface, it poses a significant safety risk in critical applications like aircraft fuselages or wind turbine blades.
The strength of composites relies heavily on the proper alignment of reinforcing fibers. Fiber misalignment can result from improper layup during manufacturing, leading to uneven stress distribution and reduced mechanical performance.
Small air pockets or voids within the composite structure can develop due to improper curing, inadequate resin flow, or trapped air. These defects reduce load-bearing capacity and may lead to premature failure.
The polymer matrix that binds fibers together can develop microcracks due to thermal cycling, mechanical stress, or environmental exposure. Over time, these cracks propagate, compromising the material’s durability.
Unlike metals, composites do not deform plastically upon impact. Instead, they may suffer internal damage (e.g., fiber breakage, hidden delamination), which can go unnoticed until catastrophic failure occurs.
Traditional inspection methods, such as ultrasonic testing (UT), X-ray imaging, and thermography, are effective but often require bulky equipment and trained personnel. However, modern portable solutions like Dolphicam2 have transformed nondestructive testing (NDT) for composites.
