Spreaders are used to control the areal weight of a fibre or fabric by increasing (spreading) or decreasing (condensing) the width of each fibre tow bundle or fabric. Spreading is often achieved by passing the fibre over a surface such as:
Often the choice of spreading technique is customised to suit the process and requirements of the fibre in each application. Customization is often achieved through lab testing at our facility.
Frequently, spreading is integrated into processes such as impregnation, in order to enhance the penetration of a material into a substrate.
In other processes, such as Uni-Directional (UD) Spreading, the objective is to achieve a target areal weight so that the material can be integrated into a composite with a tightly controlled fibre content in the composite.
