The life of a composite part is becoming increasingly challenging. This calls for the development of new composite materials with exceptional and extremely durable properties.
Looking for higher temperature resistance, higher corrosion resistance, better static or long term fatigue properties? Look at Advantex® Glass.

Advantex® Glass fibre properties and advantages in thermosets & thermoplastics
|Property in thermosets||Test Method||Unit||Advantex®||E-Glass|
|Tensile Strength*||ASTM D2343-08||MPa||2200-2600||2000-2500|
|Tensile Modulus*||ASTM D2343-08||GPa||81-83||74-80|
* Representative values of 17μm 2400 tex Advantex® Glass fibre, epoxy resin impregnated
Higher stiffness and strength make Advantex® Glass the material of choice when optimum properties are needed along load bearings.
|Property in thermoplastics||Test Method||Unit||Advantex®||E-Glass|
|Tensile Strength*||ISO 527-1-10||MPa||255-260||240-245|
|Tensile Modulus*||ISO 527-1-10||GPa||16.8-17.1||15.5-16|
* Representative values of PA compound heat stabilized reinforced with 50% GF chopped strand (10μm; 4mm).
Test made with chopped strand coated with the same sizing formulation.
Stiffness advantages of Advantex® glass has been validated in a wide range of thermoplastic resins
(PP, PBT, Styrenics, High T polymers, etc.)
Acid corrosion resistance properties
The chart illustrates the stress corrosion resistance of a pultruted rod made with an iso polyester resin and a glass roving content of 75%. The static load was around 1100 MPa. It can be seen that, in a 1N chloridric acid environment at room temperature (23°C), to reach a 50-year service, the stress level should not exceed 12.7% of the static strength. At such stress levels the E-glass rod would only survive 3.7 days.
The upper chart illustrates fatigue performance obtained on laminates made with epoxy resin and unidirectional fabrics. It can be seen that Advantex® Glass fibre improves fatigue performance by half a decade.
