Continuous Glass Fiber Reinforced Polyamide Resin

Contributing to the integration and weight reduction of various parts

With the increasing importance of environmental protection and with stricter regulations on CO2 emissions as well as fuel efficiency, the weight reduction of automobiles is becoming more and more important. Continuous Glass Fiber Reinforced Polyamide Resin (Continuous Glass Fiber) takes full advantage of the features of reinforced resin, this material has excellent strength, rigidity, and impact resistance. Therefore, the polyamide resin can be considered as an alternative to metals and contributes to the need for weight reduction.

Continuous Glass Fiber Reinforced Polyamide Resin

Product Q&A


QCan you provide us with product samples? In what condition will they be delivered?

A We can provide samples. We will deliver them in the form of prepreg (plates).

QWill you tell me the base resin and fiber type of the product?

A The base resin is PA66, and the fiber is continuous glass fiber.

QWhat applications do you predict?

A We are considering that the product can be applied to components requiring excellent strength as well as impact resistance and to strength components requiring electrical insulation as well as weight reduction. Main target products: Automobiles, robots, and other industrial products.

By substituting metal with Continuous Glass Fiber, it is possible to contribute to weight reduction and extend the mileage of automobiles.

Lightweight and high physical properties

In order to contribute to further weight reduction of automobiles, Asahi Kasei has established technologies for excellent strength, high rigidity, and high impact resistance by clarifying and controlling the mechanism of the interfacial strength development between resin and glass fiber. Since Asahi Kasei's engineering plastics have strength and impact resistance that are equal to or higher than those of metal, they can guarantee collision safety and light weight effect. Accordingly, Asahi Kasei will propose them as materials that can contribute to reliability and fuel efficiency improvement.


Excellent NVH characteristics

Since Regulation No 51 of the Economic Commission for Europe of the United Nations (UNECE) — Uniform provisions concerning the approval of motor vehicles having at least four wheels with regard to their sound emissions (R51-03) is to be enforced in 2024, the need for NVH reduction is increasing day by day in various countries around the world.
Asahi Kasei is working on the development of a compound composed of polyamide foam SunForce™ (AM), which focuses on damping characteristics effective for meeting strict regulation values, and a continuous fiber material, to meet the needs of NVH reduction. The combination of the two materials can deliver the performance for both “damping (vibration of objects)” and “transmission (penetration of sound)” with regard to the sound (noise) felt by the driver and passengers in the vehicle.

Usage example01

Bumper beam and brake pedal

Since the parts like bumper beams and brake pedals are made of metals such as iron and aluminum, weight reduction is needed. Continuous Glass Fiber has comparable strength, rigidity, impact resistance, and durability to metal. Steel bumper beams require post-processing such as bending or welding to another component. Integral molding using Continuous Glass Fiber can reduce not only weight, but also the number of processes and parts.

Usage example02

Application for Trunk floor panel

We are developing applications that utilize not only the excellent mechanical properties of Continuous Glass Fiber, but also the sound absorption and insulation characteristics obtained by combining the resin with polyamide foam SunForce™ (AM). The combination of the two materials further improves impact resistance. Furthermore, changing the thickness of the foam material can change the sound absorption frequency band. These will expand the range of applications and designs.
