Technical Information


Composition
Volume Fraction	40%	Standard
Volume Fraction	Others	On request

Yarn
Linear Density	250tex	Standard
Linear Density	125-2000tex	On request

Processing	The commingled yarn can be consolidated by heating to 180-200°C and applying a pressure of at least 1bar. Typical processes for the yarn include filament winding.

Weave Style	2x2 twill	Standard
	4x4 hopsack	Standard
	Other styles	On request

Fabric Weight	420-520gsm	Standard (depending on weave style)
Fabric Weight	250-800gsm	On request

Fabric Width	1.25m	Standard
Fabric Width	Up to 3m	On request

Processing	The commingled fabric can be consolidated by heating to 180-200°C and applying a pressure of 1-50bar. Typical processes include vacuum consolidation, autoclave and press moulding.

Preconsolidated Sheet
Thickness	0.8, 1.2, 1.6, 2.0, 2.4 & 2.8mm	Standard
	Others	On request

Processing	The sheets can be formed to shape by heating to 180-200°C and stamp forming with a matched tool in a press at typical pressures of 10-100bar.
