1. Continuous felting
(1) The product is resistant to tearing. Because the continuous felt strands are continuously formed into loops, it is isotropic and high in strength (the strength is about 1-1.5 times that of chopped strand mat) and is resistant to tearing.
(2) The surface finish of the product is high, and it can be used to decorate the surface.
(3) The designability of the product can be used for different product requirements and molding processes, such as pultrusion, RTM, vacuum casting, and molding through the change of felt layer and elasticity and different adhesives.
(4) It is easy to cut, has good flexibility and laminating properties, is easy to form, and can adapt to more complicated molds.
2. Chopped strand mat performance
(1) The chopped strand mat does not have tight interweaving points like fabrics, and is easy to absorb resin. The resin content of the product is large (50-75%), so the product has good sealing performance and no leakage, making the product resistant to water and other media The corrosion performance is improved and the appearance quality is also improved.
(2) Chopped strand mat is not as dense as fabric, so it is easy to thicken when used to make reinforced products, and the production process of chopped strand mat is less than that of fabric, and the cost is lower. Chopped strand mat can reduce product cost.
(3) The fiber in the chopped strand mat is non-directional, and the surface is rougher than the fabric, so the interlayer adhesion is good, so that the product is not easy to delaminate, and the strength of the product is isotropic.
(4) The fibers in the chopped strand mat are discontinuous, so after the product is damaged, the damaged area is small and the strength is reduced.
(5) Resin impregnation, good resin impregnation, fast impregnation speed, speed up curing speed, improve production efficiency, generally resin impregnation rate is less than or equal to 60 seconds.
(6) Laminating performance, good peritoneal performance, easy cutting, convenient construction, suitable for making products with more complex shapes
