Market Analysis: The Latest Development Trend Of Global Fiberglass Products
Owens Raikkonen (OC) has successfully developed a new type of roving for thermoplastics.
This twist free
roving
When the die is coated, the fiber bundle can be completely opened, so that hot plastic can penetrate into every root.
fibre
Therefore, fiber can avoid mechanical damage after injection molding in the end.
product
The medium fibers are evenly distributed and will not be exposed.
Because of the longer fiber, the mechanical strength of the final product has increased a lot.
Using different wetting agents, the roving can be applied to nylon, polycarbonate, acetal and thermoplastic polyester resin systems.
OC has also developed a super high strength glass fiber.
commodity
The name is ZenTron.. It is said that the tensile strength of the fiber is 50% higher than that of the traditional E glass fiber. It is higher than that of the S-2 high strength glass fiber. The product made of this glass fiber has a higher impact strength than the corresponding carbon fiber composite material 50%, and at the same time, the fiber also improves the fatigue resistance of the composite material.
At present, OC has made this kind of fiber into direct roving.
The roving of the roving is very low, and the fibers are arranged in a neat way, which is beneficial to the processing of composite materials and the strength of composite materials.
The company has developed a wetting agent system compatible with epoxy and vinyl ester.
This kind of fiber can be applied to winding and pultrusion.
Technology
It can also be woven into
Textile
It is more widely used than S-2 high strength glass fiber.
OC has also developed a new type of low foam glass fiber direct roving.
This roving is made of Borno glass, made of modern glass melting technology and advanced low foam fiber molding technology, to ensure that its bubble content is far below 0.5 g / g.
When the microbubbles in the glass decrease a lot, the formation of hollow fibers is avoided. Hollow fiber is the reason for providing electrical energy path, increasing electrical conductivity and causing system failure.
Therefore, the new direct roving has excellent electrical resistance and can be used for pultrusion FRP rod insulators for medium and high voltage pmission and distribution purposes.
A few days ago, the French Saint Gobain group, which has just been bought by OC, has successfully developed many new products, including short cut fiber / phenolic materials for automotive brake materials, special PTFE coated fiberglass insect resistant window screens for food processing plants, glass fiber / polymer fibers (polyene fibers, polyester fibers, etc.) Twintex composite fibers.
A new type of high bentonite sandwich composite felt was developed by the Saint Gobain technical fabric company in France.
The product is made of lightweight glass fiber / polyethylene fiber knitted fabric and made of short cut glass fibers with double sides stitched.
Its main characteristics are excellent laminating performance, easy operation, fast flow of resin, loose core material, low density, good overlay and smooth surface.
The product is suitable for any closed die forming process (such as RTM, light RTM and injection molding, etc.) in industries such as automobiles, boats, helmets, pipes and tanks.
The company has also developed many kinds of nonwoven mesh cloth.
It is a grid cloth bonded with a certain adhesive to weft and warp.
The standard structure is a square grid of yarns tied on the same plane.
Its main advantages are low cost and can be used for veneering materials, packaging materials and embedded reinforcement materials.
The other is a pair of vertical grids that intersects the horizontal yarns one by one.
Its main advantages are stable bonding and good stiffness.
There is also a three axial structure consisting of longitudinal yarns and two skew yarns.
Its main advantage is isotropic reinforcement, which can be used as veneering material and laminated products.
Another is a composite structure of grid cloth and wet glass fiber felt or polyester fiber felt compound.
Its main advantages are tear resistance and easy porosity control. It can be used for automobiles, roofs and flooring.
