Composites

Definition

Composites are made by combining separate elements with disparate chemical and mechanical properties.

Cogumelo manufactures polimeric composites (FRP), a combination of thermoset resins and fiberglass. Mechanical properties will vary according to the amount and orientation of fiberglass used during the manufacturing process.

Our composite materials and services are alternatives to steel, aluminum, concrete and wood. Research performed by Cogumelo concluded that our installed offshore FRP products are 42% cheaper than its steel equivalent during and interval of 18 years. Our composite products are, on average, 60% lighter than mechanically equivalent steel structures.

Advantages


  • Chemical and weather corrosion resitance.

  • Durability and low maintenance cost.

  • Low electrical conductivity and impact resistance.

  • Lightweight and structural versatility.

Resin Types

Different needs require different resins:

Polyester: provides the best cost-benefit in less critical working environments. It possesses excellent corrosion resistance and mechanical properties. Indicated for application between -4ºF (-20ºC) and 212ºF (100ºC) *.

Vynilester: provides excellent resistance in the most chemically aggressive environments. It possesses outstanding corrosion resistance and mechanical properties. Indicated for application between -4ºF (-20ºC) and 212ºF (100ºC) *.

Phenolic: provides outstanding high flame resistance, low smoke and low toxic fume emissions. Cogumelo's phenolic grating has attained Coast Guard Level 2 performance criteria and is certified under Brazilian ABNT NBR 15708 standards. Phenolic based composites are the only ones able to retain relevant parts of their mechanical properties after fire simulation tests at 1652ºF (900ºC). Indicated for application between -4ºF (-20ºC) and 392ºF (200ºC) *.

* NOTE: may vary according to working environment.
