Selcom S.r.l. produces triaxial fabrics made up of three layers of parallel fibres laid in any three orientations, stitched together with polyester yarn.
The most commonly used and known triaxial fabrics are the ones where fibres are oriented at 0º±45º (the longitudinal direction 0º is always the direction of the length of the roll and stitching direction) and fabrics with fibres oriented at +45º 90º -45º (the layer at 90° can also be placed on the outer surface of the reinforcement).
For special requests, other types of triaxial fabrics can be produced with the fibres oriented in any three directions, for example: +30º 90º -30º and so on. Remember that the orientation has to be chosen from either 0º or between ±20º and ±70º.
Somehow, it is also possible that the 0° fibres layer can be placed in between the two other plies (scarcely requested).
All reinforcements including 0º layer are available with tapered edges. During the laying of fabrics into the moulds, tapered edges are an effective way to reduce thickness build-ups when the reinforcements are overlapped. A coloured thread might be inserted to mark the start of the taper.
These items are produced in a standard width of 1270 mm or 2540 mm, and as they are stitched they can be cut without the fibres fall apart.
They can be made with any type of fibre (or hybrids, even in each layer), with a total varying weight between 200 and 2000 g/sqm and can also be supplied in combination form stitched with mat, csm, non-wovens, etc., on both outer surfaces or in between the fabric layers.
