Terms
Before the term of "advanced composites" became the standard term, this "cheap" sounding name was often used
What is "Fiber Reinforced Plastic"
An epoxy system needs this "B" part before it will cure
What is a "hardener"
When carbon fiber composites contact aluminum, watchout for this chemical reaction!
What is "Galvanic Corrosion"
Adding this light-weight material to a composite structure greatly enhances the stiffness of that structure.
What is "Core"
A curing process that evens out the resin distribution during composite fabrication.
What is "Vacuum bagging"
All stuctural parts of an aircraft which are not the power plant
What is "Airframe"
The singular unit in a polymer
What is a "Monomer"
Chopped fibers that are compressed together and bound by a starch binder.
What is "Mat"
The most commonly used honeycomb core used around the globe.
What is "Nomex
Will typically include perforated and solid films as well as a bleeder layer and a breather layer.
What is a "vacuum bag schedule"
A pressurized curing oven capable of producing the highest quality composites.
What is an "Autoclave"
A resin that can be heated and reformed over multiple cycles.
What is "Thermoplastic resin"
These fibers run parallel to the selvege edge.
What are "Warp" fibers
This core material with elongated cells will lay around a linear curve without distortion.
What is "Over expanded Core"
These ultra high pressure cutting tools are very useful in post cure processing of composite panels.
What is a "Waterjet"
What is a laminate containing insufficient resin for complete bonding of the laminate
What is "Resin lean" or "Resin starved"
This type of plastic mixes with reinforcing fibers to create advanced composites.
What is a "Matrix System"
These fabric weave types will best drape across the curves and complexities of a mold.
What are "Satin Weave fabrics"
Foam core materials such as XPS (stryrofoam) and PVC have this type of cell structure
What is a "Closed Cell" structure
A negative pressure
What is a "Vacuum"
"An increase in velocity of a fluid stream will result in a decrease pressure of the fluid stream".
What is "Bernouli's Principle"
Thermoset polymer resins need this to cure
What is a "Curing Agent"
This type of composite fabric is enhanced with this type of protection to better conduct the current situation during stormy weather.
What is " LSP - Lighning Strike Protection"
During repair, the correct honeycomb replacement core should be lined up in this direction.
What is "Ribbon"
An increase in velocity of a fluid stream will result in a drop in pressure of the fluid stream.
What is "Bernouli's Principle"
