AMS 262 Unit 1 Test – Study Guide, Practice Questions & Revision Notes
What is an SDS and what is in it? - ANS ✔✔Safety Data Sheet
Includes things like product identification, hazardous Ingredients, and Special Protection.
What should you flush an affected body area with and how long? - ANS ✔✔Clean water and for
15 minutes
What is a SRM? - ANS ✔✔Structural Repair Manual
In the ATA code what is Section 50? - ANS ✔✔Structures
What is Cohesion? - ANS ✔✔Intermingling of two surfaces (fusing) typically caused by a solvent
or heat. A method for typically used for gluing thermoplastics.
What is Crazing and what causes it? - ANS ✔✔Formation of tiny cracks in plastics. May be
caused by UV rays from the sun, ozone, chemicals, stress from cold bending, etc.
What does Monolithic mean? - ANS ✔✔Refers to a slabular or single layered structure such as
concrete.
What are thermoset plastics? - ANS ✔✔1. Requires the application of heat to harden
2. Once cured, cannot be effectively reformed (reacts to heat much like a hard boiled egg).
3. Primary use in aviation is in composite construction as a matrix.
, What are three examples of Thermoset Plastics? - ANS ✔✔1. Epoxy
2. Polyester
3. Vinyl Ester
What are Thermoplastic Plastics? - ANS ✔✔1. May or may not need heat to harden
2. Can be softened and reformed with re-application of heat (reacts to heat much like candle
wax)
3. Primarily used in aviation for aircraft transparent enclosures
What are three examples of Thermoplastic plastics? - ANS ✔✔1. Cellulose Acetate
2. Acrylic
3. Polycarbonate
What are three advantages of plastic as compared to glass? - ANS ✔✔1. Lower weight
2. Resistance to breakage
3. Safety - Glass breaks into sharp edged pieces: plastic has dull edges.
What are three disadvantages of plastic as compared to glass? - ANS ✔✔1. Scratches easier
than glass
2. Holds a static charge which attracts dirt and dust
3. Crazes when exposed to sunlight's UV rays, stress, and chemicals.
Can plastics be tinted and why? - ANS ✔✔Plastic may be tinted to reduce light penetration and
protects pilots vision and interior of aircraft.
