More Productive Capabilities

All composite parts are not flat – so why should all composite fabric be flat?  At Textum we realize that composite parts take many different shapes and sizes.  That’s why we have worked diligently over the years to develop specialty and 3D textiles in addition to our focus on flat fabrics.  Textum holds exclusive rights to multiple US and foreign patents covering 3D and shaped fabrics.

Textum’s 3-D weaving technology allows for fabrics to be woven to a specific width, length and thickness with three directions of fiber orientation.  Multiple designs are possible and they generally vary in the orientation of through thickness fibers, yarn spacing and the concentration of fiber in each weave direction.  In most cases, the in-plane fibers do not interlace with each other but instead are layers of 0/90 fabric which are “stacked” on each other and held in place by through thickness (or Z direction) fibers.

 

These multi-layer fabrics are woven in such a way that the thru thickness yarns can be used for inter-laminar property enhancement.  These fabrics can be woven up to 130 inches wide.  The number of fabric layers that are “stacked” on each other depends on the weave architecture selected but typically range from 3 to 18.   These fabrics fall into three categories due to the manner in which the thru thickness yarns are configured:

3D Fabric

Orthogonal:

Thru thickness yarns are generally at ~ 90 degree orientation to the in-plane fiber layers.

Angle interlock:

All warp direction yarns traverse fully from the top surface to the bottom surface in a repeating, sinusoidal fashion.  The warp yarns form a +/- fiber architecture in the warp / thru thickness plane.

Adjacent ply interlock:

Selected yarns from each fabric layer periodically interlace with an adjacent fabric layer, above and or below.  There will not be any thru thickness yarns that fully traverse the thickness.

The fiber fraction in all fiber directions can be tailored with a wide degree of design flexibility.  The ultimate thickness achievable will depend on the yarn denier used and the number of layers selected.

So whether you need to quickly build thickness in a part or are looking for an application specific fabric achieving very specific properties, fiber fraction volume or shapes, contact Textum today and let our engineers show you the future of 3D fabric design.
