Continuous Glass Fiber Reinforced Polyamide Resin

By using Asahi Kasei's continuous glass fiber-reinforced polyamide resin to replace metals, we are able to contribute to the reduction of weight, leading to an increase in the distance traveled by automobiles.

Light weight and high physical properties

In order to realize further weight reduction of automobiles, we are studying the mechanism of the interfacial strength development of resin and glass fiber, and are developing a technology to improve high strength, high stiffness, and high impact. We intend to propose this material as a material that can provide collision safety and light weight effects because it has tensile strength and impact properties equal to or greater than those of metals, and can also contribute to improved reliability and fuel efficiency.

Excellent NVH properties by combination with PA foaming.

In response to the enforcement of the United Nations Regulations on Automobile Accelerated Travel Noise (R51-03) in 2024, there is a growing need worldwide to reduce NVHs. We are working to develop a composite of polyamide foam (San Force® (AM)) and continuous fiber material that specializes in damping properties, which are an effective means to meet the demands of reducing NVH, in order to meet the strict regulatory limits. We believe that combining the two types of materials has the potential to achieve both “Damping: vibration of objects” and “Transmission: sound transmission” performance in terms of the sound (noise) felt by a person riding in a car.

Bumper beam, brake pedal

Metals such as iron and aluminum are used in parts such as bumper beams and brake pedals, leaving many possibilities for weight reduction. These components require materials with excellent strength, stiffness, impact, and durability. We believe that continuous glass fiber-reinforced resins that combine these characteristics are suitable. Iron bumper beams require post-processing, such as bending or welding with separate parts, but this material can reduce weight, as well as the number of processes and parts.

Use in trunk floor panels

In addition to the superior mechanical properties of continuous glass fiber reinforced resins, we are developing applications that take advantage of the sound absorption and sound insulation properties obtained by combining polyamide foam (Sunforce® (AM)). In addition to further improving the impact resistance of the composite of the two materials, by changing the thickness of the foamed material, it is possible to change the sound absorbing frequency band, thereby expanding the range of applications and designs.
