摘要: Composite structures are found in modern aircraft designs ranging from air transport to general aviation. Maintenance repair technology varies for each original equipment manufacturer and type. This research reports on two different composite methods commonly used within the aviation industry how they compare when inspected with transient infrared thermography non-destructive evaluation technique. sandwich test coupons made carbon fiber laminate, nomex honeycomb, glass laminate were this work. Impact damages generated repairs conducted by following procedures of leading manufactures. During process, controlled flaws also induced simulate bad weak bond areas, disbonds, excessive porosity. thermography, several patches identified that contained wrinkles, porosity, disbond defects the...
