Applications of pa66 glass fiber reinforced material

Today, the editor will take you on a detailed exploration of PA66 (Nylon 66) glass fiber reinforced material (commonly indicated as).PA66+GFPA66+GF30 indicates the application field with 30% glass fiber.

This material significantly enhances the mechanical strength, rigidity, heat resistance, dimensional stability, and creep resistance of pure PA66 by adding glass fibers to the PA66 matrix. However, it also reduces impact toughness and increases wear. It is precisely this combination of excellent properties that has led to its widespread application in many demanding industrial fields.

PA66+GF, due to its excellent strength, heat resistance, and oil resistance, is very suitable for use in structural and functional components within and around the automobile engine compartment.

Engine peripheralsHood, intake manifold, throttle body, radiator end tank, fan blades, etc. These components need to withstand high temperatures (up to 130-140°C) and vibrations for extended periods.

DrivetrainShift fork, clutch actuator, bearing cover, etc., require high strength and wear resistance.

Electrical and sensor componentsVarious electronic control unit (ECU) housings, sensor brackets and housings (such as oxygen sensors), connectors, etc., require good dimensional stability and insulation.

Exterior partsRearview mirror brackets, door handles, fenders, etc., require high rigidity and dimensional stability to maintain their shape.

Due to its excellent insulation, heat resistance, and flame retardancy (often achieved by adding flame retardants), PA66+GF is widely used in this field.

Circuit breakerThe enclosures, brackets, and operating mechanisms of high and low voltage circuit breakers require extremely high mechanical strength, insulation, and arc resistance.

ConnectorInternal connectors of various electronic devices (such as computers and mobile phones) require high precision, high strength, and resistance to soldering temperatures (such as SMT reflow soldering).

Coil bobbinThe framework of relays, transformers, etc. requires good insulation and dimensional stability.

Motor componentsEnd covers, fans, and insulation brackets for household appliances and industrial motors.

This is another core application area, mainly used for manufacturing high-load, high-speed precision mechanical parts to replace metal, reduce weight, and lower costs.

Gears and bearingsVarious transmission gears, cams, bearing cages, pulleys, etc. PA66+GF has self-lubricating properties and low noise characteristics.

ComponentsEnd-of-arm tooling (EOAT), robot joint components, guide rails, brackets, housings, hydraulic and pneumatic components' cylinders, etc.

Conveying systemLinks, rollers, fixtures, etc., require wear resistance and fatigue resistance.

Using its high strength-to-weight ratio (high specific strength), it is used to manufacture equipment that requires both lightweight and robustness.

Power toolsThe housings and internal structural components of electric drills and angle grinders can effectively absorb vibrations and protect the internal motors.

Sports equipmentSki bindings, scooter parts, bicycle disc brake pistons, drone bodies and brackets.

Household appliancesMotor brackets, turbine blades, lifting arms of washing machines, gearboxes, etc., for high-end vacuum cleaners.

AerospaceFor some non-load-bearing internal structural components, brackets, fasteners, etc., to meet lightweight requirements.

Military equipmentGun parts, ammunition boxes, optical equipment mounts, etc.

When choosing to use PA66+GF, it is usually for the combination of the following key advantages:

High strength and high rigidityCan withstand high loads, replace metal.

Excellent heat resistanceSuitable for long-term use in high-temperature environments such as engine compartments.

Good dimensional stabilityThe shape and size change little with variations in temperature and humidity, ensuring assembly precision.

Good chemical resistanceIt has good resistance to oils, fuels, and many chemicals.

Reducing weight and costCompared to metals, it has a lower density, can be lightweight, and is easy to form complex parts through injection molding, reducing processing costs.

Potential DrawbacksThe disadvantages are increased brittleness (reduced impact strength), anisotropy (uneven shrinkage easily leading to warping), and significant wear on processing equipment. Therefore, these factors need to be fully considered in design and use.

In summary,PA66 glass fiber reinforced material is a crucial engineering plastic.It is applied in almost all industrial and consumer product fields that require strength, heat resistance, and dimensional stability, making it an indispensable material in modern manufacturing.
