Composites FAQ's
Q. What is a composite?
A. A Composite is a combination
of two or more materials yielding properties superior to the individual
ingredients. One material is in the form of a particulate or fiber (called
the reinforcement or discrete phase). The other is formable solid (called
the matrix or continuous phase). The region where the reinforcement and
the matrix meet is called the interface. Composite properties are determined
by chemical mechanical interaction at the interface as well as the properties
of the combined materials. Fiber glass reinforced plastic (FRP or GRP)
combines fiber glass (the reinforcement) with thermoplastic or thermosetting
resins (the matrix).
Q. What are the advantages of composite?
A. While materials like metal are
strong, this strength is equal in all directions. The advantage of composites
is that strength characteristics can be custom tailored in a specific
direction. Placing more material where needed and less where it is not,
is one of the major advantages of composites over other materials.
Q. How do we design with FRP?
A. The variation in design options,
resins and reinforcement selection, and molding process that give composite
materials an advantage over other materials can also make working with
them a bit more complicated, especially when one needs to maximize the
quality and reduce costs. The key is to match the correct variables with
the application.
