Composite Materials Flashcards
What is a composite material by defintion?
Two or more materials that differ in composition are used together, but not mixed.
The bonding substance is called a _______
Matrix
The strength of the composite material comes from the __________ ________
Reinforcing Material
The __________ is the most important part, and is the space between the matrix and reinforcing material
Interface
What are the disadvantages of composites versus metal
No signs of stress/impending structural failure
Moisture weakens the structure
High initial cost to produce composites
More expensive materials
What are some of the safety concerns with composites?
Toxic Vapours
Toxic dust
Industrial Dermatitis
Blindness
_________ is made of molten glass that has been drawns into a fine strand, the stands are then spun and sewn together to form a cloth
Fiberglass
E-Glass is the common type of fibreglass, made of _________
Borosilicate
S-Glass is manufactures from _________-_________ __________, and is used for very high tensile strength applications
Magnesia-Aluminum Silicate
________ is more commonly known as Kevlar, and is flexible
Aramid
_________ ________ is very high in compressive strength and stiffness, and will produce corrosion when bonded to metals
Carbon Fiber
_________ is mostly found in military applications, is also carcinogenic
Boron (With Tungsten)
_________ is used in high heat applications, like the hot sections of a turbine engine
Ceramics
Cases where the load forces are known and always run in the same direction are called _____________ fibres
Unidirectional
___-___________/_____-___________ fabrics are fabrics where the major fibres are woven so that they run in 2+ directions
Bi-Directional/Multi-Directional
