CFM (continuous filament mat) is commonly used for pultrusion process. It has advantages of fast impregnation and high strength. However it’s easy to be jammed and broken in mold due to its thickness.

Now more and more fabricators like to use veilmat (polyester veil stitched to chopped strand) as substitute of CFM. Veilmat has the following strength compared to CFM:

1. Veilmat is stitched, so it’s thinner. Chopped length of fiber (same fiber as CFM) is 10cm. This gives higher strength to veil mat.  Joints can be stitched or overlapped, which is easy for operation.

2. Polyester veil has feature of anti-aging & water resistant, and also gives good surface.
