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

Glass
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

Carbon
Basalt
LCP ( liquid crystal polymer)
High tenacity polymers (HT polymers)

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.

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

  • 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.
