A great influence on quality of the glass fiber is used in the process of the tensile surface active agents.
Ingredients used in the surface active agents such as setting machine, lubricants, coupling agent and other additives affect the processing performance and the performance of the reinforced plastic.
The effect of coupling agent is part of the molecular and reinforced material form chain, and the other part can react with matrix resin, improve the bonding force of interface between resin and glass fiber, so as to improve the mechanical properties of composite materials, electric properties and aging resistance.
Used for glass fiber coupling agent is mainly silane coupling agent.
glass fiber three methods: 1. Before the treatment, in the process of glass fiber drawing impregnated by infiltrating agent make the fiber surface by chemical treatment. 2. Post-processing, heat the glass fiber or fabric to remove surface lubricant, then dip coating agent. 。 3. Migration method, coupling agent and compatibilizer involved in resin.
the difference between carbon fiber and graphite fiber depends on the carbon fiber, carbon content in 90% 99% for the carbon fiber, carbon content is higher than 99% as graphite fiber, its manufacturing principle and structure are the same. Carbon fiber can be made from polyacrylonitrile or asphalt, but the quality of the carbon fiber at present can only be made by PAN. CF need the surface treatment in order to improve the polarity of the fiber surface, improve the fiber by resin can be wettability and fiber/matrix bondability. Present problems of the carbon fiber is a high price, low interlaminar shear strength and impact strength. Electrical conductivity of carbon fiber in the performance of the special is that it and the linear expansion coefficient of the fiber axis axis, the specific performance is the cause of the carbon fiber can be widely used.
twisting filament yarn can also be used to reinforced plastics, although they are more conducive to injection molding processing, but the twisted yarn impregnated with thermosetting or thermoplastic resin is more difficult, therefore, not twisted yarn is more advantageous to reinforced plastics. Short fiber to thermoplastic polymer, thermosetting plastics and paper, such as the provision of fiber length is 3 - commonly 6mm。
carbon fiber using the enhancement of the substrate is engineering plastic. Carbon fiber reinforced thermoplastics can obtain high rigidity, high strength and lightweight composite material. At the same time, because the linear expansion coefficient of carbon fiber is negative, so it can be used to manufacture composite materials with zero linear expansion coefficient, or create another kind of material coefficient of thermal expansion and the same composite materials.
