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.

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.
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.
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.
