Since its introduction, Oxeon’s ±45° version of TeXtreme has been a gamechanger for those seeking a continuous ±45° spread tow fabric, the leading manufacturer reports. Due to the increased demand, Oxeon has invested EUR 3 million to expand the company’s patented ±45° Spread Tow weaving capacity.
Known for its ability to reduce weight, increase stiffness and strength, improve impact protection, as well as improve dampening performance in thin plies, TeXtreme Spread Tow Fabrics extend these benefits found in its 0°/90° fabrics to its ±45°continuous length fabrics which are available in widths up to 60”/1.5m, according to the manufacturer.
Some of the benefits of using ±45° TeXtreme to replace traditional UD layups, are said to be labour savings through faster throughput during the layup process as only one ply needs to be laid down rather than two plies. Also, scrap is reduced by eliminating the waste associated with bias cutting edge triangle waste.
In addition, the use of the new fabric is said to result in easier layups, reduced number of plies, consistent ±45° angles throughout the laminate, eliminated need for splicing, and an increased handling stability in both dry and prepreg forms.
TeXtreme’s nonexistence of stitching or fixation yarn is said to minimise the risk of mechanical issues, such as micro cracks, along with eliminating the difficulty in predicting mechanical performance due to the induced geometrical variation caused by the stitching or stabilizing/fixation yarns found in its meso structure.
“We can clearly see a need for this product, especially in aerospace applications where the knock-down factor of mechanical properties has limited the usage of existing ± oriented textiles,” said Henrik Blycker, CEO of Oxeon.
“TeXtreme technology does not require stitching or fixation yarn so, unlike NCF solutions, larger profile parts such as panels, wings or tubes that use TeXtreme have no knock-down factor so this means that the parts are stronger while being much lighter. With this additional investment in TeXtreme Spread Tow Fabrics, we’re further enhancing our position as the advanced carbon reinforcement technology leader.”
TeXtreme, the market leader in advanced carbon reinforcement technology, is used for making advanced ultra-light composites products with superior mechanical performance and surface smoothness.
TeXtreme Technology is flexible and tow-size independent, which helps to enable the development of optimised reinforcement solutions, which are tailor-made for specific needs of the application. Manufacturers of advanced aerospace, industrial and sports products have consistently found that using TeXtreme Spread Tow carbon fabrics and UD tapes have enabled them to produce composite parts which are 20-30% lighter with improved mechanical properties and superior surface smoothness, the company reports.
