LFT-G PPS ポリフェニレンサルファイド複合長炭素繊維 熱可塑性樹脂 オリジナルカラー 12mm

PPS

Special engineering plastics are engineering plastics with higher overall performance and long-term use temperature above 150℃, PPS is one of them.

The carbon fiber reinforced special engineering composites formed by carbon fiber as the reinforcement and these special engineering plastics as the matrix have excellent mechanical properties, wear resistance and high temperature resistance, which can be used in aerospace, marine or medical fields, and in some aspects show more desirable application advantages than thermosetting resins or even metal materials.

PPS-LCF

Polyphenylene sulfide PPS resin strength and hardness are relatively high, good mechanical properties, adapt to a variety of molding and processing methods, you can achieve secondary precision molding, the dimensional stability of the product is better. Its moisture absorption rate of only 0.03%, low density, melt temperature Tm of 285 ℃, the glass transition temperature Tg of 90 ℃, thermal stability is very good, in the air state, to reach 430 ℃ -460 ℃ before decomposition, high flame retardant grade, 200 ℃ insoluble in most organic solvents, excellent electrical insulation. As a special engineering plastics, PPS advantages are outstanding, but defects also exist, for example, because of the large number of benzene ring to make its impact resistance and elongation is not good enough, but through the carbon fiber reinforced way, can further improve the performance of the material strength and thermal stability, so as to better show the value of the application of the material.

Through the carbon fiber reinforced intervention, changing the original insulating properties of PPS into a conductive, anti-static properties, polyphenylene sulfide PPS toughness and strength can be substantially increased and improved, becoming one of the most commonly used composite materials in the aerospace field. It is used in aircraft landing gear, wings, hatches, fuel tank port covers, J-shaped nose cone, cabin interior trim and other components, not only to help increase the impact resistance, high temperature and corrosion resistance of these parts, more through the reduction in mass, to enhance the aircraft load efficiency and reduce fuel consumption. Compared with metal, this composite material has the advantages of low cost and easy processing, the cost can be reduced by 20-50 percent.

炭素繊維強化材と PPS 樹脂マトリックスの間で高い結合を維持する必要があります。製品が応力を受けたとき、この高度な結合により、界面が外部荷重を効果的に繊維に伝達できるようになり、複合材料の機械的特性が向上するだけでなく、界面間の剥離による亀裂を効果的に防ぐことができます。樹脂マトリックスと炭素繊維強化材の間で高い結合を形成するには、溶融状態のPPS樹脂と炭素繊維強化材を完全に接触させ、完全に含浸させ、繊維体が均一に分散した状態で良好な分散を実現する必要があります。含浸効果。
