Select the manufacturing method that can be use with open and closed molds

• Pulstrusion

• Resin Transfer Molding

• Compression molding

• Hand lay-up

The choice of molding method is typically driven by:

• Materials being used

• Complexity of the shape

• Production rates

• All of the above

Select the mannufacturing methoc that cannot be use with thermoplastic

• Filament winding

• Prepeg hand lay-up

• Wet hand lay-up

• All of the above

Select the manufacturing processes that use continuous fibers only

• Filament winding

• Compression molding

• Pultrusion

• Infusion

What is the main function of peel-ply?

• Prevent parts from sticking to the mold or fixture, regardless of the process

• Facilitate resin movement, removal of excess resin, and extraction of aire and gas from the laminate during process

• Release the laminate from subsequent bleeder or breather layers

• Restrict or prevent resin flow

What is the main function of vacuum bag?

• Provide compaction pressure and consolidation of the plies within the laminate

• Maintain a breather path throughout the system to the vacuum source, so that air and volatiles can escape, and uniform atmospheric pressure is applied to the laminate

• Absorb resin from the laminate through a perforated release film

• Release the laminate from subsequent bleeder or breather layers

What type of raw material does the compression molding process use?

• Bulk Molding Compound

• Sheet Molding Compound

• Preforms

• All of the above

What type of raw material does the fiber placement process use?

• Preforms

• Woven fabrics

• Roving

• Tapes

Only autoclaves have heaters and fans that provide convection heating in a manner that uniformly distributes the heat throughout the vessel

• True

• False

Ovens are normally cylindrical and usually have simple hinge/latch mechanisms because they have no internal pressurization capabilities. Autoclaves are rectangular in shape and have door-locking design to provide clamping, sealing, and safety functions during use.
