Aerospace 

The replacement of metal materials or thermosetting composite materials by high-performance thermoplastic composite materials on large passenger aircraft has become a direction for the development of new materials and new technologies. Various developed countries and aviation organizations have increased research in this area. As the first thermoplastic material to be used in the aerospace industry, PEEK (PAEK) is now an integral part of aerospace materials. PEEK (PAEK) polymer materials are extremely robust, chemically inert and flame retardant, and easy to process. The advantages of components with extremely small tolerances have been officially approved by many aircraft manufacturers and are also in line with the requirements for the supply of military standard products.

A variety of new PEEK (PAEK) polymeric materials and composite grades currently available from Hengbo not only optimize mechanical properties, but also improve molding processability.

Main performance

High temperature and high 

temperature  

stability 

Due to the semi-crystalline structure of PEEK (PAEK) polymer material, its mechanical properties are still good at temperatures above the glass transition temperature. Compared with other common high temperature thermoplastic materials, PEEK (PAEK) polymer materials High temperature resistance is more stable.

Flame retardancy

PEEK (PAEK) polymeric materials are also excellent in flame retardancy. PEEK (PAEK) has a flame retardant rating of UL94 V-0. The flame retardant properties are inherent to the material and do not require the addition of any flame retardant materials such as halogen additives. The data measured for the soot produced by the burning of plastic materials showed that PEEK (PAEK) polymeric materials had the lowest specific optical density values among all the tested materials.

Toxic  

gas release

The amount of toxic gases produced by PEEK (PAEK) polymeric materials is minimal when burned. Its pyrolysis products are mainly carbon dioxide and carbon monoxide.

Thermal expansion coefficient

The addition of filler to the PEEK (PAEK) polymeric material reduces the coefficient of expansion to a level comparable to that of metal. Therefore, the metal component can be directly replaced by a polymeric material component without any problems caused by uneven expansion.

Strength

Compared to metals, PEEK (PAEK) polymeric materials have high tensile strength and low density. Reinforced with glass short fibers or carbon fibers, the strength-to-weight ratio is comparable or superior to that of conventional aerospace materials. Long fiber reinforced composites made of PEEK (PAEK) polymeric materials have significantly improved strength and rigidity.

Chemical resistance

PEEK (PAEK) polymeric materials have excellent chemical resistance and are resistant to a wide range of acids, bases and hydrocarbons including aviation fuels. When the PEEK (PAEK) composite was immersed in aviation hydraulic oil at 70 ° C for 1000 hours, its tensile strength, tensile modulus and tensile elongation decreased by less than 5%.


Car 

In the context of environmental pollution, in order to achieve the purpose of reducing weight and energy saving, the use of traditional steel, iron, copper and other materials in automobiles has been gradually reduced, and the consumption of new lightweight materials has gradually increased. In particular, the development of plastic-based composite materials is very fast, playing an important role in the field of plastic-substituted steel.

Jiangsu Hengbo Composite Materials Co., Ltd. produces a variety of thermoplastic materials including PEEK (PAEK) polymeric materials. These high-performance thermoplastics maintain stable mechanical properties in high temperature environments above 140°C to meet the latest demands in the automotive industry. A recent study showed that PEEK (PAEK) polymeric materials can retain their original stiffness, tensile strength and impact strength after 5,000 hours of use: while traditional materials such as PPA and nylon have a performance degradation of up to 50 under the same conditions. %. PEEK (PAEK) thermoplastic polymer materials have a melting temperature above 340 ° C and a glass transition temperature above 140 ° C, which can adapt to harsh environments.

Main performance

High mechanical strength

PEEK (PAEK) polymeric materials maintain their mechanical properties well in working environments above their glass transition temperature.

Tensile fatigue performance

Hengbo's carbon fiber reinforced PEEK (PAEK) material is not only easy to process, but also has high mechanical properties and fatigue resistance.

Thermal expansion

Fillers added to PEEK (PAEK) polymeric materials can reduce the coefficient of thermal expansion (CTE) of materials to levels comparable to metals. Therefore, when a metal part is directly replaced with a polymeric material member, there is no risk at all due to the difference in expansion coefficient.

Tolerance

The tolerances of Hengbo's injection molded parts are usually within 0.05% of the specified size.

Specific strength

PEEK (PAEK) polymeric materials have high tensile strength and low density. Reinforcement with fiberglass or carbon fiber allows the strength-to-weight ratio of polymeric materials to meet or exceed common lightweight materials. The strength and rigidity of continuous fiber reinforced composites using PEEK (PAEK) polymeric matrix exceeds the strength and rigidity of some metallic materials.

PEEK (PAEK) outperforms standard aluminum alloys in terms of weight and profile thickness. Compared with ternary alloy brass materials, the size can be almost achieved. It's exactly the same.

Creep

Both filled and unfilled PEEK (PAEK) exhibited excellent creep resistance at room temperature. When the temperature exceeds the glass transition temperature (Tg), only enhanced PEEK (PAEK) is suitable for structural applications. The apparent modulus of PEEK (PAEK) is in many cases higher than the tensile/bending modulus of other high temperature resistant thermoplastics.
