In the modified engineering plastics industry, long fiber reinforced composite material refers to long carbon fiber, long glass fiber, aramid fiber or basalt fiber and polymer matrix, through a series of special modification methods to produce composite materials. The biggest characteristic of long fiber composites is that they have superior properties that the original materials do not have. If they are classified according to the length of the added reinforcement materials, they can be divided into long fiber, short fiber and continuous fiber composites. As mentioned in the beginning, long carbon fiber composite material is a kind of long fiber reinforced composite material, which is a new fiber material with high strength and high modulus fiber. LCF carbon fiber composite exhibits high strength along the fiber axis, and has the characteristics of high strength and light weight. It has the comprehensive mechanical properties such as density, specific strength and specific modulus that are incomparable to other materials. It is a new material with excellent mechanical properties and many special functions. What are the properties of Long Carbon fiber?

Compared with glass fiber, LCF carbon fiber composite has higher strength, higher rigidity, lower weight, and excellent electrical conductivity. What is the application fileds of PA66-LCF? 1. Military industry LFT long carbon fiber composite has very high specific strength and stiffness, and has the characteristics of corrosion resistance, fatigue resistance, high temperature resistance and low thermal expansion coefficient, etc. LCF carbon fiber composite is widely used in rocket, missile, military aircraft, personal protection and other military fields at home and abroad. Compared with conventional materials, long carbon fiber composites allow for continuous improvements in the performance of military equipment, such as reducing the weight of warships by 20 to 40 percent. 同時に、LCF炭素繊維複合材料は、金属材料が腐食しやすく、疲労しやすいなどの欠点を克服し、軍事製品の耐久性を向上および強化します。現在、LCF 炭素繊維複合材料の 40% 以上が一部の先進的な軍用ヘリコプターに使用されており、無人航空機ではさらに多く使用されています。航空機に加えて、海兵隊の軍艦にも長い炭素繊維複合材料が使用されています。これは、長い炭素繊維複合材料が海水やさまざまな化学不純物の腐食に耐えることができ、耐用年数が長く、鋼鉄軍艦よりも耐久性があり、メンテナンスコストが低いためです。 、現代の防衛軍事兵器および装備の開発にとって重要な戦略物資となっています。 2. 家電分野 LCF炭素繊維複合材料は、低密度、優れた耐薬品性、優れた性能などの特性を備えており、徐々に家電業界で好まれる改質エンジニアリングプラスチックとなり、その使用量は約30％を占め、増加傾向にあります。さらに、家電製品はますますインテリジェント化およびパーソナライズされており、材料の改良された性能要件はより高くなります。したがって、長炭素繊維複合材が家電業界に選ばれるのも不思議ではありません。 1、グリーンおよび環境保護：従来の材料と比較して、製造プロセスは比較的シンプルですが、より環境保護、より経済的であり、高光沢、形成が容易、耐傷性、リサイクル可能な特性を備えています。 2、安全性と高い安定性：サイズの安定性が良好で、低温および高温の使用環境に適応でき、変形の問題が小さく、安全に使用できます。 3、高い耐疲労性：長期間使用でき、クリープが小さく、総合的な機械的特性が優れています。 4.軽量：密度が低いため、完成品の重量が軽くなり、毎日の使用に便利です。 3. 風力タービンブレード 風力タービンの重要なコンポーネントの 1 つはブレードです。風力タービンブレードの製造では、空気力学的影響、技術プロセス、複合材料の構造を考慮する必要があり、ブレードの長さは風力タービンの出力に比例します。ブレードの全体の質量は大きくありませんが、ファンの中で 15% ～ 20% を占める最もコストの高い部品であるため、ブレードを作成するための材料の選択は非常に重要です。 ファンブレードは表面の汚染物質や粗さの影響を受けにくく、構造的に可能な限り厚いブレード形状を使用する必要があります。風に耐えられる疲労回復回数が多ければ多いほど良い。ブレードの長さが長くなると、強化材の強度と剛性に対して新たな要件が求められます。大型複合ブレードの製造におけるガラス繊維の性能は明らかに不十分です。LFT 長炭素繊維複合材料を使用することは、ブレードの質量要件を軽減し、強度と剛性の要件を満たす最良の方法です。 より強力な風力発電設備とより長いローターブレードの開発では、より優れた性能を備えた LCF 炭素繊維複合材料が使用されるのが一般的な傾向です。さらに、一定のサポートがあれば、長いカーボンファイバーブレードはグラスファイバーブレードよりも安価であり、材料の消費、労働力、輸送、設置コストが削減さ...

Long carbon chain nylon is nylon with an amide group in the main chain repeating unit of nylon molecule, and the length of methylene between the two amide groups is greater than 10. We call it long carbon chain nylon, including nylon 11, nylon 12, etc. PA12 is nylon 12, also known as polydodecactam, polylauractam, is a long carbon chain nylon. The basic material for its polymerization is butadiene, a semi-crystalline - crystalline thermoplastic material. Nylon 12 is the most widely used long carbon chain nylon, in addition to most of the general properties of nylon, low water absorption, and has high dimensional stability, high temperature resistance, corrosion resistance, good toughness, easy processing and other advantages. Compared with PA11, another long carbon chain nylon material, the price of butadiene, the raw material of PA12, is only one third of the price of castor oil, the raw material of PA11. It can replace PA11 and be applied in most scenes, and has a wide range of applications in automobile fuel pipe, air brake hose, submarine cable, 3D printing and many other fields. In long chain nylon, compared with other nylon materials, PA12 has great advantages, such as the lowest water absorption rate, the lowest density, low melting point, impact resistance, friction resistance, low temperature resistance, fuel resistance, good dimensional stability, good anti-noise effect. PA12 has the properties of PA6, PA66 and polyolefin (PE, PP) at the same time, achieving the combination of lightweight and physical and chemical properties, and has advantages in performance. There are a large number of non-polar methylene groups in nylon 12, which makes nylon 12 molecular chain more compliant. The amide group in nylon 12 is polar, and the cohesion energy is very large, it can form hydrogen bonds between the molecules, so that the molecular arrangement is regular. Therefore, nylon 12 has high crystallinity and high strength. Nylon 12 has low water absorption, good low temperature resistance, good air tightness, excellent alkali and oil resistance, medium resistance to alcohol, inorganic dilute acid and aromatic hydrocarbons, good mechanical and electrical properties, and is a self-flameout material. 1) Density The relative density of nylon 12 is only 1.01-1.03, which is the smallest among all engineering plastics, which has a certain effect on reducing the quality of vehicles and reducing fuel consumption. When compared by unit volume, nylon 12 has advantages in price and performance. 2) Melting point The melting point of nylon 12 is 172-178℃, slightly lower than nylon 11, can fully meet the requirements of automobile fuel pipe and brake pipe working environment temperature. 3) Water absorption As we all know, the biggest disadvantage of nylon products is large water absorption, dimensional stability is difficult to ensure. And PA12 has the lowest water absorption rate of nylon products, this is due to the methylene molecules in nylon 12 greatly reduce the hydrophilic groups, which makes nylon 12 has a great advantage. 4) Impact strength Impact strength is an important technical index, especially for nylon 12 pipe often exposed to air. Nylon 12 under -20℃ and -40℃ according to the standard test, no fracture phenomenon, fully meet the requirements of use. Nylon 12 has excellent impact resistance. 5) Low temperature performance Nylon 12 has the lowest brittleness temperature of -70 degrees Celsius, so it can be widely used in low-temperature resistant parts. 6) Flexibility The influence of plasticizer on the physical properties of nylon 12 is concentrated on the elastic modulus of resin. Nylon 12 has three basic types of resin, their main difference is due to the plasticizer content of different forms of flexibility. The elastic modulus of resin decreases with the increase of extractable component content of plasticizer. 7) Low wear and low friction performance Nylon 12 has excellent low abrasion and low friction properties and self lubricating properties, so the friction noise of nylon 12 products is very low. 8) Fuel resistance In automobiles, the mixture of oxygenated fuel, high aromatic fuel and alcohol currently used can cause the breakdown of many hose materials. After the test, only nylon 11, nylon 12 and fluorocarbon resin elastomers can be used in this environment. Almost other types of nylon melt under the action of automobile fuel, resulting in a change in size. 9) Resistance to zinc chloride solution Zinc chloride is found under the car. Under certain temperature and humidity, the salt on the road reacts with galvanized steel plate or zinc-containing primer to form the corrosive zinc chloride. In addition, ozone aging, ultraviolet radiation, temperature conditions and so on, will bring different degrees of damage to the parts, reduce the service life. Nylon 12 is very resistant to zinc chloride solution. Because there is no unsaturated double bond in nylon 12 which is susceptible to ozone attack, ozone ...
