COMPOSITES

DEFINITION COMPONENTS MATERIALS

What is a composite material?

Materials manufactured by man whose properties

are superior to those of their constituents separately.

FIBER (estructural frame)

+

POLYMER/MATRIX (form the component)

 

 

 

FIBER (estructural frame)

  • Supports most of the load
  • Provides resistance and rigidity
+
 

MATRIX (form of the component)
 
  • Join the fibers together
  • Transfer loads to fibers
  • Protects fibers from the environment
  • Gives the composite material the surface appearance

MOST USED FIBERS:

    • CARBON: Fiber of organic origin and
inorganic transition.
  • ARAMIDA: Fiber of organic origin.
  • GLASS: Inorganic fiber.
 

RESINS (thermostable) MORE USED:

  • Epoxy
  • Polyester
  • Vinyl ester
  • High temperature matrices

 

PROCESSES

  • Infusion
  • Pultrusion
  • RTM
  • Filament Winding

ADVANTAGES

Composite materials are ideal for almost any civil work and for a wide variety of uses.
