Question | Answer |
---|---|
Carbon Fibers | Fibers produced from pyrolytic degradation of synthetic organic fibers ex:PAN or Rayon |
Adherend | a part prepared for bonding |
Adhesion | a mechanical or chemical interface between two surfaces |
Adhesive Failure | break in the adhesive bond |
Air-Bubble Void | air-entrapment |
Autoclave | an enclosed object while undergoing a chemical reaction (with or without heat) |
Batch | aka LOT, a quantity of material formed having identical characteristics through-out |
Bias Fabric | a fabric in which warp and fill fibers are at an angle to the length |
Bleeder Cloth | not part of final composite but is used to "bleed" out excess gas and resin during cure |
Bond Strength | the amount of adhesion between bonded surfaces |
Breather | loosely woven material like glass fabric that doesn't come into contact with resin, and is later removed b4 final composite |
Bridging | Condition when fibers don't conform to corners resulting in voids and dimensional problems |
Core | the central component of a sandwich structure |
Core Crush | compression of the core |
Cross Laminated | layers of material laminated |
Cure | a chemical reaction with or without heat |
Cure Cycle | time/temp/pressure cycle used to cure a resin system |
Curing Agent | a catalytic agent added to resin to speed up process |
Debulking | manual cure cycle used to prevent wrinkles |
Delamination | the separation of laminated plastic material |
Compressive Strength | a materials ability to resist a force that tends to crush or buckle |
Composite | a material created from a fiber to enhance performance properties |
Cohesive Failure | failure of an adhesive joint |
Cohesion | the force holding a single substance together |
Co-Cured | cured and simultaneously bonded to another prepared surface |
Cell | a hexagonal shaped honey-comb core |
Cavity | the female portion of the mold |
Catalyst | the drying or curing process |
Draft Angle | The angle of a mold that requires removal of the finished part |
Dry Laminate | a laminate containing insufficient resin for complete bonding |
Dry Lay up | construction of a laminate on mold followed by bag molding or autoclave |
E-Glass | Electrical Glass EX:battery, AGM glass mat bat, boats, shower,etc. (used where ever Fiber glass will get wet-water attacks resin not the mat) |
Exotherm | the evolution of heat during the curing of a plastic product |
Fatigue | the failure or decay of mechanical properties after repeated applications of stress |
Fatigue Strength | maximum cyclical stress a material can hold b4 failure occurs |
Fraying Surface | the surfaces of material in contact with each other |
Fiber Direction | the alignment of the fiber in respect to a stated reference |
Fiber Orientation | the fiber alignment in a non-woven or mat laminate |
