fibre types

Glass

  • High tensile and compressive strength
  • High tensile and compressive modulus
  • Low density (app. 2,6 g/cm³)
  • Low thermal extension
  • High thermal stability
  • High chemical stability
  • Low electrical conductivity

Carbon

Carbon fibres are more expensive than glass fibres, but offer various advantages:

  • Very high tensile and compressive strength
  • Very high tensile and compressive modulus
  • Low density (app 1,8 g/cm³)
  • Low thermal extension
  • High thermal stability
  • High chemical stability
  • High electrical conductivity

Aramid

Aramid fibres are used predominantly for bullet-proof and impact-resistant protective materials. Their advantages are:

  • High tensile strength and stiffness
  • Excellent impact properties
  • Low density (app. 1,44 g/cm³)
  • High chemical stability

Basalt

Basalt fibres (derived from vulcanic rocks) are used as a substitute for Glass fibres in some applications. Has better properties against alkali , higher tenacity, higher modulus than E-glass.

LCP ( liquid crystal polymer)

is an aromatic polyester with properties in some cases better in some cases inferior to aramid.

High tenacity polymers (HT polymers)

  • HTPET (High Tenacity PET)
  • High Tenacity PA6, PA66, PA 46
  • HTPP (High tenacity PP )

High tenacity polymer fibres are used in flexible and protective materials.

HT yarns are also used for producing SRP (self reinforced plastic) in particular for production of srPET , srPP, srPA.
