Composites Flashcards
(24 cards)
A combination of two or more individual materials
Composite
States that better property combinations are fashioned by the judicious combination of two or more distinct materials
Principle of combined action
Cellulose fibers encased in lignin
Wood
Composed of a soft protein called collagen and a brittle mineral called apatite
Bone
Uniform, continuous and made of a single material
Monolithic
Non-uniform, discontinuous, multiphase
Composite
Multiphase material that is artificially made
Composite
a continuous phase type
Matrix
is discontinuous and surrounded by matrix
Dispersed
Its purpose is to transfer stress and protect the dispersed phase
Matrix Phase
Spheroidite steel, cemented carbide, and automobile tire rubber are examples of
Particle-reinforced
Concrete is a type oF
Particle Reinforced Composite
reinforced with steel rebar or remesh
reinforced concrete
rebar/remesh placed under tension during setting of concrete
prestressed concrete
tighten nuts to place concrete under compression
posttensioning
provide significant strength improvement to the composite
fibers
continuous glass filaments in a polymer matrix
fiber-glass
are thin single crystals - large length to diameter ratios
Whiskers
are polycrystalline or amorphous and are generally polymers or ceramics
Fibers
are metals such as steel, molybdenum and tungsten
Metals
is when continuous fibers pulled through resin tank to impregnate fibers with thermosetting resin
Pultrusion
Continuous reinforcing fibers are accurately positioned in a predetermined pattern to form a hollow shape.
Filament Winding
Are stacked and bonded fiber-reinforced sheets
Laminates
have honeycomb core between two facing sheets
Sandwich panels
