Non-crimp multiaxial technical textiles or fabrics made from multiple layers of unidirectional placed and stitch bonded FILAVA™ fibers permits to obtain higher tensile strength and flexural properties in the reinforced composite materials.
The downstream processability is easier notably the wettability and resin infusion while it is much convenient to cut or handle the fabrics as the stitching yarn holds the fabric stable.
They are available in wide range of surface, weight and construction pattern (angle combination), including Unidirectional 0/90°, Biaxial +/- 45° or 0/90°, Triaxial, Quadriaxial, ...etc.
Non-crimp technical textiles made from FILAVA™ are available in a nominal surface weight range of 200 to 1.200 gr/m², all with a roll’s width of 127 cm.
Non-crimp fabrics have excellent wettability and are compliant with various matrices or resins systems for thermoset or thermoplast applications: epoxy, vinylesther, polyurethane, polyamide, …etc.
They are suitable for various structural end-use applications: in aircraft, automotive, nautical and many other domains where fiber-reinforcement layers can be placed in different orientations with aim to optimize the performance of the composites whilst improving the shock absorption.
FILAVATM is a direct roving made of enhanced volcanic rock filaments and manufactured in the melt spinning process. FILAVATM roving is a unique product thanks to a genuine and innovative treatment of the raw material, volcanic rock, which being the major ingredient, is aggregated and enriched with various mineral; additives with the aim to increase and guarantee its original mechanical and chemical properties as well to maintain the evenness of the required mechanical properties. The components used in the batch aggregation and the fabrication process are ISOMATEX’s know-how and constitute its exclusive expertise.
Single-End and Multi-End assembly direct rovings consist thousands of continuous filaments with elementary diameters from 9,0 to 11,0 μm. bonded into a single strand. A specially developed by matrices’ type sizing is applied on the fiber, which guarantees an excellent infusion and resin-to-reinforcement adhesion.
FILAVATM is unique due to its high strength, high elasticity and resistance to high temperature as well as to temperature’s variation (contrarily to carbon which does not like thermal shocks). This compares well to existing high-end products (R - glassfibers, S - glassfibers).
