One problem that occurred during the inspection process was the delamination of the composite material. This has meant designing more powerful engines, and lighter aircraft. Fiberglass composite material is a composite material made of glass fiber and epoxy resin. Engineers cum scientist tries to design a material which is lighter in weight and high in strength. Especially for smaller airplanes, carbon fiber composites are the best choice. It is also known as the strength/weight ratio. Amorphous thermoplastics are available in several physical forms, curing stages of resins, Prepreg material consists of a combination of a matrix and fiber reinforcement. Advantages offered by composites in these kinds include their capability to bond nicely with many substrate materials and cling to complicated shapes. Similar to heat resistance, certain composite materials such as Aramid fiber can yield high-impact resistance properties. Durable. The fibres are set into resin to form sheets which are laid on top of each other, bonded and then heated in a large oven, or “autoclave”. Advantages of Composite Materials in Aircraft Structures. Resilience – the ability to deform and spring back to their original shape without major damage. The main advantages and disadvantages of composite materials used in aircraft are: Lightweight is the biggest advantage of using composite materials. Special inspectors known as non-destructive testing technicians can perform more detailed inspections which gives them the ability to look inside the composite materials. It has high creep resistance. of the aircrafts to reduce the development and operating costs. Consolidated Parts and Function. Composite materials can drastically cut down on the weight of an aircraft, which leads to better performance and improved fuel efficiency. This useful feature can reduce maintenance and therefore the cost over the life of the aircraft. Strength-to-weight and stiffness-to-weight are greater than in steel or aluminium. 09 - Composite Materials – September 2018 Composite materials have been utilised in the aerospace industry for many decades, initially in non-safety critical applications and more recently as primary structures, including fuselage and wing structures on the latest aircraft from Boeing, Airbus, and Bombardier. They have several advantages over traditional aluminium alloys. Another passenger benefit to composites is that due to their very stiff material properties, windows can be larger. ... Another advantage of composite materials is that, generally speaking, they can be formed into more complex shapes than their metallic counterparts. Chemical Resistance. It is … Disadvantages The biggest disadvantage of composite materials is their higher initial cost compared with metals.

High Impact Strength. In this way, composite material selection in aircraft structures can be optimized for the specific flight performance required. Defects in aircraft composite materials include delamination cracks, skin-core interfacial cracks, voids and dry spots. Aircraft technicians can perform visual inspections to composite materials. Another big advantage of composites is their design flexibility: They can be made […] * Matrix is weak, therefore, low toughness. But … Resistant to fatigue/corrosion 6. Carbon in composites INTRODUCTION The most commonly used composite materials in aviation are carbon fiber, fiberglass, fiber-reinforced matrix systems, or a mixture of these materials. The main advantage of designing with composite material is the reduction of weight. Add to this are the advantages of improved aerodynamics, lower fuel costs, increased efficiency and requirement for fewer parts – no wonder why carbon fibre composite materials are fast emerging as a top-notch aircraft building material today. Another big advantage of composite materials is their design flexibility: they can be made into rough shapes. Ordinary RC (reinforced concrete) is composite section, each component provides some degree of advantage to it, for example in RC steel provides tension resistance while concrete provides compression and buckling resistance adding to durability and reduction in cost.

Design Flexibility. Key among them are strength, light weight, corrosion resistance, design flexibility and durability. Aluminum is sensitive to tension loads. With less weight in the aircraft structure, significant operational cost savings are realized; payload yields increased, maintenance costs decreased, and greater flight range is obtained, among many other positive attributes. In addition, it is difficult to determine when the internal structure of composite aircraft components has been damaged. Composites consist of two or more materials that, when combined, will provide structural properties and performance capabilities not obtainable from any one material component alone. As carbon composites are, in general, only 60% of the density of aluminium, they provide a much better strength-to-weight ratio than metals: sometimes by as much as 20%. Composites offer other advantages over aluminum, too: Composites are excellent at handling tension – In highly tension-loaded applications, such as the fuselage of airplanes, this helps decrease fatigue and maintenance.
