Textile Composites

What is Composite?

Composite materials are materials that are formed in order to combine two or more same or different groups of materials in a single and new material with the desired features dominant and the undesired features eliminated in accordance with the design purpose.


Although composite essentially means a mixture, it does not have dissolving and dissolving components and is distinguished from alloys due to their insoluble properties. There is no chemical interaction between the components that make up the composite and there is no exchange of atoms.



The components of composite materials are reinforcement material and matrix material. Reinforcement materials are used for weight reduction in most composite production. It is a matrix material with a continuous (uninterrupted) volume and usually in greater amount from the components. As a basic logic, the improvement of the properties is achieved by means of reinforcing elements mixed into the matrix materials.


Properties of Composite Materials;

  • It has a reinforcement phase embedded in a continuous matrix material.

  • While the reinforcement material and the matrix act on their own before being combined, they act as a single material after combining.

  • Reinforcing materials have at least micro-level dimensions.

  • While the reinforcement materials carry a load, the matrix materials have the task of protecting the reinforcement.


The advantage of a composite material, if it is well designed, is that it exhibits the best of its components and has some properties that are not observed in any of its components.

Some properties can be achieved by producing composite material. These; properties such as mechanical strength, pressure, tensile, bending, impact resistance, fatigue resistance and abrasion resistance, corrosion resistance, fracture toughness, high temperature resistance, thermal conductivity or electrical resistance, acoustic conductivity, sound retention or sound absorbing, stiffness and weight gain.


Textile Composites

Textile composites can be defined as composite structures obtained by macro-dimensional combination of matrix material and fiber, yarn or fabric as textile reinforcement material. In these structures, the textile component provides strength and dimensional stability.


Textile composites have high strength and stiffness at low densities, high energy storage behavior and excellent fatigue performance.


Composite materials using inorganic and organic fibers (fiberglass, carbon, aramid, polyethylene, polypropylene, etc.) are produced in textiles. In this field, glass fiber composite textiles can be given as an example. It is made of glass fiber, polyester fiber and glass fiber.



Textile composites are used in the automotive industry such as shafts, side rails, doors, oil tank, leaf springs, wheels, truck bodies, engine cover, hinges, bumpers, seat supports, as well as main body manufacturing, trunk products such as luggage compartment, side walls, floor, ceiling, in the aircraft industry such as sinks, cargo bays, aerospace products such as missiles, rockets and satellites, in the marine industry such as boat hulls, sonar domes, antenna, buoy, mast and mast, submarine, and golf clubs, surfboards, javelin, jump pole, hockey It is used in the production of sports equipment such as sticks, ski sticks, tennis rackets, bicycle frames and helmets, canoes and catamarans.
