Factors affecting the fiber dispersion and uniformity of choppedstrand mat, such as glass strand quality, equipment, environment and personal factors, are introduced and analyzed.
Wet reinforcement fibers such as wet choppedstrandglass fibers are opened by passing the fibers consecutively through a first opener (210), a condenser (220), and, optionally, a second opener (230).
A method of forming a choppedstrand mat formed of bonding materials and wet use choppedstrandglass fibers (WUCS) which demonstrate a reduced occurrence of static electricity is provided.
