What’s the 3 classifications of damage?
Repairable, non repairable and negligible
What’s the 3 classifications of damage?
Repairable, non repairable and negligible
What’s BVID stand for
Barely visible impact damage
What NDI’s are used for detecting moisture
Moisture detectors and thermography’s
How’s ultrasonic inspections work
By sending ultrasonic waves through the metal
What are the two types of adhesives
Film and foam
What are the two forms that sealants come in
One part and two part
One part can be used as it came from manufacturer
Two parts have to be kept separate and mixed together in order to cure
Where should a transparent plastic be marked
If it’s in a permanent frame then should be marked on the frame instead of window if not it should be printed on the inner face of the window
What’s used to mark thermosetting plastics
Vibroetching
What are the two types of transparent plastics
Monolithic and laminated
What’s the most common form of plastic
PTFE
What plastic is a common substitute for metals
PAI
What plastic can withstand large amounts of radiation
PEEK
What are the advantages of using plastics
Corrosion resistant
Chemical resistant
Impact resistant
Lightweight
Why isn’t foam used a core material on commercial aircraft
Because it’s weaker and heavier than honeycomb
What’s the main advantage of sandwich composites over laminate composites
Extremely strength to weight ratio
What’s the difference between laminate and sandwich composites
Sandwich is a core it’s two composite sheets bonded either side of it
Whereas laminates are 2 or more layers of bonded composites
What’s the most common thermoset
Epoxy resin
What are the two categories of matrix
Thermoset and thermoforming
What’s the different types of weave
Plain
Satin
Twill
Which of the 3 weaves has the best drape qualities
Satin
What’s unidirectional, bidirectional, matted and quasi isotopic lay up
Uni directional is in one direction
Bi directional is it two or more directions
Matted is chopped fibres
Quasi is layers of weave layered in 45 degrees alternation
What’s the warp, fill, bias and selvage edge
Warp is the length of the fabric
Fill is the length between left and right side of fabric (90 degrees from warp)
Bias is 45 degrees from warp
Selvage edge is the edge that prevents it from fraying
What’s ceramic used in
High-temps
Why isn’t boron used in aircraft
Because it’s expensive and dangerous
