Fibreglass is used in the composite industry as a reinforcement and is available in different forms that will specifically be chosen according to your application and your requirements. MCtechnics offers the entire range of available glass reinforcements. The standard glass reinforcement is made from E glass. Other glass chemical formulation (e.g. ECR glass) are available upon request.
- DIRECT ROVING:
Mainly used for pultrusion and filament winding and produced from 300 tex up to 9600 tex. Several sizings are available to be compatible with the resin type as well as the application.
- SPRAY UP ROVING:
Assembled roving of 2400 tex with specific sizing in order to have good cutting properties and compatible to polyester resins. These rovings are normally sprayed with a chopper gun.
- CHOPPED FIBRES:
Chopped fibres up to 12 mm can be used as reinforcement for casting system and bounding paste.
- CHOPPED STRAND MATS (CSM):
Made of randomly oriented fibres which are connected to each other with a binder which will be dissolved by the styrene in the polyester resin. There are two main kinds of binders: powder and emulsion. Available from 150 to 900 g/m², fibre tex is usually 30 Tex but CSM can also be produce with fine tex (15Tex) fibre to avoid print through.
- CONTINUOUS FILAMENT MATS:
Mats made of continuous fibre bonded with a binder soluble in styrene. These are often used for RTM and pultrusion.
- WOVEN ROVINGS:
Plain weave made of fibreglass and used to create more strength in a composite due to the high fibreglass /resin ratio. These woven roving are often used in combination with Chopped Strand Mats or Gun roving and are available in different weights and different weaves such as square or twill. These woven rovings can be used with Polyester, Vinylester and Epoxi resins. Standard woven roving weight: 200, 300, 600 and 800 (all other weight available upon request). The Fibres used to weave those riving is usually 2400 Tex.
A wide range of fabric is available covering all weaving patterns: Twill (2x2 and 4x4 being the mostly used), Tafta (all types) and Plain weave. The range of weight available is from 80 to 1200 g/m². Fibre tex used to weave those fabrics is usually finer than for woven roving giving those fabrics a better aesthetic. Sizing of the input material defines the fabrics resin compatibility.
- NON-CRIMP FABRICS – MULTIAXIALS:
Non-crimp fabrics, also known as multiaxials, are distinguished by their stretched fibres inside the individual layers, to absorb optimally mechanical forces on the composite part. They are available in four different types:
- Unidirectional complexes – in both 0° and in 90° direction. This stitch bonded material is produced with reinforcing threads.
- Bidirectional complexes in 0°/90° direction.
- Triaxial fabrics: 0/-45/+45° as standard but angles between 22.5° and 90° possible.
- Quadriaxial fabrics: 0/90/-45/+45° as standard but angles between 22.5° and 90° possible.
Remark: Those non-crimp fabrics can be produced as complex structures in combination with stitched mat whenever necessary.
Woven roving can be combined with a stitched mat to lead to a combi-mat structure which is defined as such for the standard version:
- 300 / 300: 300 g/m² Woven roving + CSM of 300 g/m²
- 800 / 450: 800 g/m² Woven roving + CSM of450 g/m²
