ABSTRACT:
Aligned fibre mats are produced by passing a continuously accelerating or decelerating stream of fibre dispersion over a permeable surface and simultaneously withdrawing a limited proportion of the dispersion liquid through the permeable surface to deposit aligned fibres thereon. Mats having a wide variety of shapes and alignment patterns may readily be produced and may subsequently be impregnated with resins, metals etc. to form fibre-reinforced composite materials.
