  • What is composite


    A composite material (also shortened to composite) is a material made from two or more constituent materials with significantly

    different physical or chemical properties that, when combined, produce a material with characteristics different from the individual

    components. The individual components remain separate and distinct within the finished structure. The new material may be

    preferred for many reasons:common examples include materials which are stronger, lighter, or less expensive when compared

    to traditional materials.


    Typical engineered composite materials include:

    1.Composite building materials, such as cements, concrete

    2.Reinforced plastics, such as fiber-reinforced polymer ( FRP)

    3.Metal composites

    4. Ceramic composites (composite ceramic and metal matrices)


    What is FRP

    Fibre-reinforced plastic (FRP) (also fibrereinforced polymer) is a composite material made of a polymer matrix reinforced with fibers

    The fibres are usually glass, carbon, aramid, or basalt. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic,

    and phenol formaldehyde resins are still in use.


    These materials work in concert to provide a specific set of strength and performance

    properties,  including:

    1. Light weight with high strength

    2. Corrosion free and impact resistant

    3. Dimensional stability

    4. Electrically non-conductive( Fiberglass products)

    5. Non-magnetic and non-sparking

    6. Low thermal conductivity

    7. Rapid installation with standard tools

    8. RF transparency



    Traditional materials have their place. But for harsh, corrosive or other specific environments,  Huahao’s FRP is a smart choice.

    Contact Huahao Composites Co., Ltd for RFQ today!


    Huahao pultruded FRP products have the strength of steel at a fraction of the weight. It won’t corrode, rot, attract insect damage

    or conduct electricity. It can be formed into countless FRP profiles to fit your specs. And decades later when those other materials

    need to be replaced, it will still have plenty of life.
