Future Aviation Use of Lighter Materials



The future of lightweighting is a topic of intense debate in the aviation sector. One organization with interest in researching this subject is the Aerospace Industries Association. The main topics of discussion are listed below. These subjects include iStream Superlight, 3D-woven technical textile, carbon fibre, and bio-based composite resin. Lightweighting in aviation has a bright future and the potential to revolutionize the sector.

Fibre carbon

The sports goods industry is one of the drivers of the rising demand for carbon fibre. Due to its high strength and lightweight, this material offers designers and manufacturers flexibility when creating products. In 2016, China held the largest regional market share for carbon fibre, with India not far behind. The emphasis on recycling materials and lowering carbon emissions are two key factors driving the market in India. Recycling lowers overall production and manufacturing costs in addition to reducing carbon footprint.

But the cost of carbon fibre is high. Its production calls for expensive materials and high levels of precision. Even though it isn't currently inexpensive, it will be in a few decades. Various products, including enormous wind turbines, have utilized carbon fibre. Many manufacturers are still wary of its costs and advantages, but the material's high demand and rising price fuel its expansion.

technical textile 3D-woven

Engineers have created a brand-new category of technical textiles known as 3D-woven at the University of Surrey. These materials can withstand intense vibrations and are very rigid. They also possess excellent sound-dampening capabilities. These materials were initially used in cars to strengthen the body shell, but engineers soon discovered they could add space to the vehicle.

Engineered preforms remove the complexity of manual composite fabrication processes. Lightweight composites can be created using the 3D weaving process in hours instead of days. Engineered performs raise output as well. The adoption of 3D fabrics is anticipated to be fueled by these benefits. Technocrats will continue to create new fabrics, procedures, and materials as 3-d textiles continue to gain popularity.

Superlight iStream

Unique chassis designs for each model variant are to be replaced by Gordon Murray Design's iStream Superlight, a new automotive manufacturing system. The iStream system, initially created for Formula One racing, is now offered in an evolution known as "Superlight." It consists of honeycomb recycled carbon composite panels on an aluminium, thin-wall tubular frame.

Gordon Murray Design is creating a new lightweight sports car based on the technology in addition to the iStream Superlight. It is anticipated to weigh only 2,000 pounds, a tiny portion of a Mazda MX-5 Miata. The vehicle's powertrain comprises a 1.5-litre three-cylinder turbocharged engine and six-speed manual transmission. The 2.0-litre engine in the Mazda Miata generates 181 hp. Murray intends to sell the technology to any manufacturer, with TVR being the first to do so. 2019 will see TVR's entry into the Griffith sports car market.

composite resin made from plants

The MAESO brand of bio-based composite resin is a brand-new product. It has several advantages over traditional unplasticized resins (UPRs), but its properties are comparable to those of conventional UPRs. It is biodegradable and works well with other substances, such as metal and wood. It can be recycled as well. Additionally, it is anticipated to reduce carbon footprint, allowing for use in various applications.

Although bio-based composites have been on the market for a while, most academic literature and research concentrates on their potential uses. Comparing bio-based materials to synthetic ones, there are clear environmental advantages. However, bio-based composites have several disadvantages, including flammability, poor thermal resistance, and variation across fibres. Bio-based feedstocks are also challenging to produce and sell. Although it is a growing source of worry, industry competition also catalyses innovation in bio-based feedstocks.
