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
-

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.
