Reinforced Plastic

Reinforced plastic is obtained through a cure process, where there is an aggregation of the resin with reinforcement. This reinforcement can be fiberglass, aramid fiber or carbon fiber. Is necessary to evaluate the final application needed before choosing the reinforcement.

For this application, Fibertex offers the following products:

Fiberglass Fabric


 Fiberglass fabrics used to reinforce plastic composition are structuralized on the unidirectional, bi-directional and multiaxial forms in different standards (drawings: leno, twill, satin, crow feet) and in several weights (from 50 g/m² to 1500 g/m²), providing great flexibility of application, conciliating the slightness, resistance to chemical deterioration, dimensional stability, dielectric properties and resistance to the humidity.

 

Carbon fiber fabric

Slightness, rigidity, resistance, low thermal deformation and satisfactory thermal conductivity: these are some of the properties of the carbon fiber that make it one of the best options for manufacturing of reinforced plastic parts. The reinforced plastic with carbon fiber has its origin in the space equipment developments and it is used since 1967 in this area.
It is used also in airplanes, sporting materials (tennis rackets, golf-clubs, poles of fishing, bicycles), in the automotive industry (Formula 1), building construction, etc.


 

Aramid fiber fabric

The reinforced plastic with aramid fiber fabric presents some advantages in relation to other fibers. We must always remember that the choice of the fiber to be used in the reinforced plastic must be established in the objective and requirements of the final application.
The aramid fiber has low specific weight in comparison with other fibers; it conciliates great resistance and rigidity allowing the use of less material to get the same mechanical characteristics; it is resistant to fissures; it increases the rigidity of the structure; it has high absorption of energy and low widening; it does not corrode itself in water nor in aquamarine and it is incombustible.

 

Hybrid fabrics

According to the final application requirements, the fabrics also can be produced combining carbon fiber, aramid fiber and fiberglass, in the following forms:

  • fiberglass + carbon fiber,
  • fiberglass + aramid fiber and
  • aramid fiber + carbon fiber.

 

Yarns


Yarns also are used for plastic reinforcement. See more details in yarns.
