Polyester surfacing tissues made of polyester fiber with high strength, not easy to wear and break through wet process, without any adhesive material. Tissue surface is high, uniform and flat, soft to feel, good air permeability and other characteristics, giving polyester surfacing tissues applied in FRP products with resin affinity function, resin penetration and formation of resin rich layer on the surface of FRP products, eliminate bubble and white stain phenomenon and cover fiber lines, improve the surface finish of FRP and anti-leakage performance, at the same time,It has excellent corrosion resistance. Especially for hydrofluoric acid (HF) and oxidation components or solvents, so that it still maintains good physical properties and dimensional stability in the liquid. The UV resistance stability of polyester surfacing tissue can effectively improve the UV resistance of glass fiber surface, so that the glass fiber products can be protected in texture, color and other aspects, and improve the anti-aging ability.
The product is widely used in pultrusion process, winding process, hand paste process, vacuum injection process. Such as: ship, plate, light tile, car board, wind turbine blade, storage tank, pipe, profile, radome, etc.
The application of polyester surfacing tissue in FRP helmet
The application of polyester surfacing tissue on fiberglass helmet is realized by hand paste process. Polyester surfacing tissue on helmet can play the role of rich resin, so that glass fiber and resin can be well combined together, enhance the mechanical properties of the helmet surface, but also improve the finish of the helmet surface. The glass fiber should not leak out so as to prevent the direct contact between human body and glass fiber. In order to better protect the human skin from glass fiber damage.
Second, the application of polyester surfacing tissue in honeycomb panel manufacturing industry
Polyester surfacing tissue is copolymerized with polyester fiber modification, so that it has a strong affinity and resin, than other materials have the following unique product characteristics.
First, Using the softness and plasticity of polyester surfacing tissue, other honeycomb panels are seamlessly combined to create a sweeping strip combining honeycomb panels with other panels.
Second, Polyester surfacing tissue through fiber modification, and resin or other adhesives have strong permeability and adhesion, so that honeycomb board and other materials bond without cracking, no delamination.
third,he polyester surfacing tissue is processed into a mesh structure, which enhances the bonding area between the resin and the board, reduces the phenomenon of air leakage and ventilation in the composite process, and makes it more sound insulation.
Fourth, polyester surfacing tissue itself has extremely superior anticorrosive material, at the same time resistance to hydrofluoric acid is its strength, has a wide range of applicability.
