—

It can be used in a variety of molding processes such as hand lay-up, molding, RTM, winding, etc. It is flexible in processing and can adapt to complex structures and curved components.

Wettability

—

After contact with the resin, it is easy to quickly penetrate and wet evenly. It is suitable for a variety of thermosetting resins to reduce operation time and improve the density and mechanical properties of the finished product.

Mechanical properties

—

Multi-directional reinforcement, good interlayer strength, balanced reinforcement effect, improved product bending, tensile and impact strength, suitable for structural parts or shell products

Bubble release

—

The fibers are loose, there are many exhaust channels, the resin has good fluidity, reduces bubbles, and improves the appearance quality and mechanical properties.

Surface smoothness

—

The surface is uniform, the thickness is stable, and there are few burrs. The finished product has a beautiful appearance and is suitable for surface treatment such as spraying and electroplating.

Easy to operate

—

Easy to cut and lay, suitable for molds of various sizes and shapes. High construction efficiency, wide adaptability, and convenient for manual/automatic production
