Fibre manufacture gets more efficient

Continuous fibreglass weaving specialists, Victrex Polymer Solutions, has developed an innovative composite fabric, TIXPREF.

The fabric is made out of unidirectional tapes formed from S2-glass or carbon fibres that have been fully impregnated with high performance VICTREX PEEK polymer.

It's hoped TIXPREF composite fabrics will reduce the cycle time by up to 50 % or more for parts required for press forming. TIXPREF has excellent mechanical properties that result from the high fibre content of up to 65 %.

Being thermoplastic the TIXPREF fabrics have a higher damage tolerance when compared to thermoset-based fabrics, high fatigue strength and stiffness, and excellent integration of the fibre with the matrix, resulting in a longer lifetime for the composite part, plus a reduction in its structural weight. The fabrics are easy and safe to handle, thus well suited for automated processes and out-of-autoclave manufacturing methods.

The materials has service temperature of up to 260°C, high resistance to harsh chemicals and solvents, and exceptional wear resistance, and provide superior mechanical properties under both static and dynamic load conditions. VICTREX PEEK polymer is solvent-free and recyclable and being thermoplastic in nature can be stored at ambient temperature eliminating the need for expensive cooling and storage costs.
