AFAB 120 CHAPTER 9 EXAM QUESTIONS
WITH 100% CORRECT ANSWERS
When routing, once the depth has been determined, use the template to trace around
the edges of the cut-out, then using a back-and- forth motion, remove honeycomb core.
- Answer-True
47 1/1 point
A band saw can be used to trim composites if it has a ——— tooth blade (12 to 14 teeth
per inch - Answer-Fine
Waterjet cutting does not produce dust or fumes and causes no delamination or fuzzing
of aramid laminates. - Answer-True
Waterjet cutting is used most often in the ——- process and is not commonly used for
infield repair applications. - Answer-Manufacturing
Laser cutting can be performed only on cured composite materials, and the pieces can
be many layers thick, so many parts can be made with one cutting. - Answer-False
Composites vary in their toxicity ; you should treat all composites as equally hazardous
and observe appropriate safety precautions when working with any of - Answer-True
Composites are more susceptible to material failures when machined , making hole
quality important . - Answer-True
Which types of failures that can occur while drilling composites . - Answer-Delamination
Which type of failure most often occurs as the peeling away of the bottom layer as the
force of the drill pushes the layers apart , rather than cutting through them - Answer-
Delimitation
Which type of failure occurs when the bottom layer splinters as the drill completes the
hole . - Answer-Breakout
Which type of failure occurs when a crack forms along one of the layers from the force
of the drill . - Answer-Fracture
To combat problems in drilling, use wood as a backing to the material being drilled OR
use a ———- - Answer-Drillstop
