Common Plastic Materials Used in the Aerospace Industry

In the aerospace industry, the selection of materials is crucial, especially those used in aircraft and spacecraft. Given the strict demands for lightweight, high strength, and high-temperature resistance, choosing the right plastic materials is essential for ensuring the performance and safety of flying vehicles. This article will introduce the common plastic materials used in aerospace applications and their specific uses, helping you better understand the characteristics of these materials and their importance in the aerospace industry.

Common Plastic Materials and Their Applications

Below are several commonly used plastic materials in the aerospace industry, each with distinct properties suited to different aerospace applications.

Professional Application Insights for Various Plastics

1. Polycarbonate (PC) — The Perfect Combination of Strength and Transparency Polycarbonate (PC) is a colorless, transparent engineering plastic with exceptional impact strength, far exceeding most common plastics. Its excellent transparency and heat resistance make it widely used in aircraft windows, cabin screens, and light covers. In addition to providing clear visibility, polycarbonate can resist UV radiation, extending the lifespan of in-cabin equipment.

2. Polyamide (PA) — Superior Wear Resistance and Corrosion Resistance Polyamide, commonly known as Nylon, offers excellent wear and corrosion resistance, making it ideal for engine parts, fuel systems, and other high-load, high-pressure components. The presence of amide groups in its molecular chain allows it to resist a wide range of chemical agents, while maintaining strength and stability at high temperatures—an essential material in the aerospace field.

3. Polytetrafluoroethylene (PTFE) — Outstanding Chemical Resistance and Low Friction PTFE is used in aircraft fuel pipelines, seals, and insulation materials. Its exceptional chemical stability allows it to perform well in extreme environments. Another significant feature of PTFE is its extremely low friction coefficient, which improves the performance of sliding parts by reducing wear and enhancing the longevity of components.

4. Polyetheretherketone (PEEK) — The Ideal Choice for High-Temperature Environments Polyetheretherketone (PEEK) is a high-performance plastic known for its outstanding strength and temperature resistance, often used in aircraft engine parts and electronic device housings. It can withstand temperatures up to 250°C and provides excellent electrical insulation properties, making it perfect for demanding aerospace applications.

5. Polyvinyl Chloride (PVC) — Cost-Effectiveness and Reliability Although polyvinyl chloride (PVC) does not offer the same high-temperature resistance as other materials, its low cost and strong corrosion resistance make it an ideal choice for many aerospace applications. PVC is commonly used for cable insulation, piping systems, and low-load components. Its simple molding process and adaptability make it a versatile option.

6. Polyethylene Terephthalate (PET) — Strength and Environmental Responsibility PET is increasingly used in aerospace applications for composites and seat components. Its high strength, good UV resistance, and recyclability make it popular in the industry. With growing environmental awareness, PET’s recyclability offers both economic and environmental advantages for manufacturers and airlines alike.

The Role of Aerospace Thermoforming Technology in Plastic Processing

The aerospace industry places high demands on material performance, and choosing the right materials, such as those detailed above, is crucial for the safety, reliability, and performance of flying vehicles. In the processing of these plastic materials, aerospace thermoforming technology plays a vital role, especially when producing complex shapes and high-precision components.

Thermoforming is a process where plastic sheets are heated to a certain temperature and then stretched or pressed into the desired shape. This process not only enables the efficient production of high volumes of parts but also ensures the strength and structural integrity of the materials. In aerospace, thermoforming is commonly used to create complex components such as aircraft fuselages, seat parts, and cabin instrument panels, offering significant production efficiency and cost benefits.
