forms the volume of the composite material within.

Classify the following givens above according to their appropriate groups:

are comprised of a variety of short or continuous fibers bound together by an organic polymer matrix.

metals and alloys are used as matrix materials.

is a composite material consisting of carbon fiber reinforcement in a matrix of graphite.

both the reinforcement (refractory fibers) and matrix material are ceramics.

it improves the overall properties of the matrix and serves to strengthen/reinforce the composite.

Classify the following givens above according to their appropriate groups:

 A type of composite that uses tiny particles as its dispersed phase.

one has the matrix of the ferrite which is the alpha phase

also called a ceramic metal composite.

matrix of rubber

The interaction between the faces should be threaten at a continuum level

Concrete is a common large-particle composite

The ingredients for this concrete are Portland cement, a fine aggregate (sand), a coarse aggregate (gravel), and water.

Classify the following givens above according to their appropriate groups:

Metals and metal alloys may be strengthened and hardened by the uniform dispersion of several volume percent of fine particles of a very hard and inert material.

___________  are composed of axial particulates embedded in a matrix material.

Elastic modulus can be put between an upper and lower limit.  Also known as the _________.

Classify the following givens above according to their appropriate groups:

Fibers can be short, long, or evencontinuous.

Fibers often fracture because of surface imperfections. 

A greater volume fraction of fibers decreases the strength and stiffness of the composite, as we would expect from the rule of mixtures.

Fibers can also be arranged inthree-dimensional patterns

In most fiber-reinforced composites, the fibers are weak, stiff, and heavy. Thus the specific strength and specific modulus of the fiber are important characteristics.
