Nonwovens have a wide range of applications in the aerospace industry and can be used to manufacture a variety of aerospace materials and equipment. Nonwovens are fiber mesh structures formed directly from fibers or interlining paper without traditional processing methods such as weaving or braiding. This special manufacturing process gives nonwovens the advantages of light weight, high strength, thermal insulation and good wear and corrosion resistance. In the modern aerospace field, these advantages make nonwovens one of the ideal materials for manufacturing aerospace equipment.

Introduction

The application of nonwovens in the aerospace field is mainly based on their special advantages such as light weight, high strength and thermal insulation properties, such as the manufacture of space suits, fuel filters, radiation protection materials, etc.. All these applications require the use of high performance materials to meet the requirements in extreme environments. For example, small, low-speed UAVs are needed for various complex measurement tasks. In this case, the UAV needs to be lightweight in design and must also have sufficient load-bearing capacity and flight stability performance. In this case, nonwoven fabric is often chosen as one of the materials.

Application areas

Aviation field In the aviation field, nonwovens are widely used, such as aircraft interiors, air conditioning filters, fuel filters, etc. In aircraft manufacturing, nonwovens are widely used to make the walls, floors and ceilings of aircraft interiors, and they are ideal for making seats and other seat accessories due to their lightweight and soft characteristics. In addition, nonwovens can be used as materials for air conditioning filters. With its high filtration efficiency and low resistance, it can purify the air inside the aircraft, making the air inside cleaner and fresher.

Space field In the space field, the application of nonwoven fabrics includes space suits, radiation protection materials and heat insulation materials. Space suits are essential equipment for astronauts on space missions. Due to the extremely low temperature of the external environment in space, the insulation function of space suits is very important. Nonwoven fabrics can be made into radiation-proof materials that can protect astronauts from the radiation and temperature in the space environment. The insulation must be sufficiently insulating to stop the conduction of heat and thus protect the astronauts and the spacecraft. The good thermal insulation property of nonwoven fabric makes it an ideal thermal insulation material.

Application characteristics

Lightweight Nonwoven is a lightweight material, which is light and soft and can effectively reduce the total weight. In the aviation field, lightweight is a very important design consideration. As airplanes and other aircraft continue to be upgraded and improved, the total weight of an aircraft can be reduced through the use of lightweight materials such as nonwovens, resulting in improved fuel efficiency.

High strength Compared to other materials, nonwovens have greater tensile strength and tear resistance. In the aerospace field, many equipment and facilities require the use of high-strength materials. Nonwovens are tougher and more durable due to the disordered nature of the fibers and multiple interlacing, allowing them to withstand the challenges and stresses of being in an aerospace environment.

Abrasion and corrosion resistance In aerospace, materials are often exposed to harsh environments, such as high temperatures, high pressures, high speeds and other extreme conditions. Nonwovens have excellent abrasion and corrosion resistance to withstand these extreme environments, resulting in a longer service life.

Excellent Thermal Insulation Thermal insulation is a very critical issue in aerospace equipment manufacturing. Nonwovens have good thermal insulation properties because of their loose structure and low heat transfer properties, which can effectively prevent heat transfer, thus protecting astronauts and other facilities from high temperatures and other effects.

Application cases

Space suit Space suit is the necessary equipment for astronauts to carry out space missions. Nonwoven fabric can be used as heat insulation material in space suits because of its good heat insulation performance. By using nonwoven as insulation material, it can effectively protect astronauts from the high temperature and radiation in space environment. This material also has good breathability and softness, which allows the astronaut to bend his body freely for operation.

Air Conditioning Filters Inside the aircraft, air conditioning filters are needed to purify the air. Nonwoven fabric is widely used as the main material for air conditioning filters because of its good filtration performance, high filtration efficiency and low resistance.

Aircraft external protection cover In flight, aircraft and facilities often need an external protection cover to protect them from various substances and the external environment. Nonwoven fabric can be used as the main material for the protective cover due to its advantages such as abrasion resistance, water resistance and corrosion resistance. In the case of harsh external environment, the high abrasion and corrosion resistance of nonwoven fabric ensures that the equipment and facilities are always in good condition.

Development Prospects

With the continuous development of aerospace technology and manufacturing process, the application of nonwoven fabrics in the aerospace field will be more widely promoted and used. Currently, the aviation industry and manufacturers are focusing on developing more lightweight structures and materials to reduce the UNIT cost (price per seat) of aircraft. Nonwovens will be an important direction in this new structural material, and thus more widely used in the aviation industry.
