What Are Composites

Learn about the many benefits of composites, and all the ways they are important to our everyday lives.

About Composites

A composite is a material made from two or more different materials that, when combined, are stronger than those individual materials by themselves.

Composites 101

Composites solve problems, raise performance levels and enable the development of new innovations.


There are three types of composite manufacturing processes: open molding, closed molding and cast polymer molding.


Composites are composed of fiber reinforcements and a resin matrix that bonds the fibers.

Benefits of Composites

Composites offer many benefits. Key among them are strength, light weight, corrosion resistance, design flexibility and durability.

Composites Compared

Composites are gaining traction in many industries, from architecture to infrastructure and automotive. They offer clear advantages that make them an ideal replacement for a variety of materials, including steel, aluminum, wood and granite. Composites are fast becoming the material of choice.

  • Composites vs. Steel

    Composites are lighter, incredibly strong, corrosion resistant, nonconductive, and allow for parts consolidation

  • Composites vs. Aluminum

    Composites can handle tension, create one-piece designs, allow for precise weight distribution, are strong yet flexible, and absorb vibrations

  • Composites vs. Wood

    Composites are long lasting, dimensionally stable, low maintenance, easy to transport and install, and resistant to pests

  • Composites vs. Granite

    Composites are non-porous, easy to maintain, inexpensive, heat resistant, and offer endless appearance options
