Chapter 3 Flashcards
What is the primary purpose of a clean room?
Is an area within your facility where you can maintain a clean environment free of dust, dirt, oil and any other contaminates that should not come in contact with the composite materials
The clean room temperature should be maintained at
63-73 degrees F
The focal point of your clean room will be:
Cutting Table
The importance of having a “self-healing” surface on your cutting table is:
[ All of the above] ability to cut on the surface repeatedly, cut in a safe controlled manner, longevity of knife blades reducing cost.
Name the 3 different types of vacuum systems:
Venturi Vacuum Pump, Rotary Vane Pump, Industrial Rotary Vane Pumps
List 4 advantages of the Venturi vacuum system:
Compressed air driven (easy to install), compact size (allows pump to be placed closer to point of use), light weight construction, no moving parts (extra long pump life).
List the 4 curing options:
room temp, oven cure, autoclave cure, portable composite curing equipment
What type of cure should be chosen when looking to produce the most superior cure?
Autoclave cure
Why is composite dust collection necessary?
[All the above] reduce health hazards, reduce contamination of materials, ensure integrity of final part.
List 3 dust collection methods:
Point of source collection, dust collection booth, multi-point source collection
A dust collection booth is ideal for:
Entry and intermediate level shop
The Venturi vacuum pump is named after
18th century physicist G.B. Venturi
What is the importance of having a freezer to store prepreg materials?
The materials slowly degrade, freezing slows the process
List the advantages of walk-in freezer vs. a chest freezer.
Segregate materials, separate materials by type, maintaining inventory, FIFO rotate old stock, store laidup/not cured materials for future assembly.
List the advantage of “pre kitting.”
Helps determine both materials and quantity needed, minimize thaw time, reduce material waste, ergonomic values, long-term storage.
