Composites Plant

Mitaş Composites operates in its modern factory located in Ankara ASO 2nd Industrial Zone. The facility, which was commissioned in 2018 by Mitaş Energy, became a company under the name Mitaş Composites Plastic Industry and Trade Inc. in 2019 and will continue to provide services to all its customers by working on innovative composite products with its experienced staff in design, production and assembly, environmentally friendly technology, R&D and quality laboratory.

This facility uses filament winding method up to 12 m length and 1000 mm dimensions in its high-quality and capacity computer-aided machines. Also, all the supporting operations from winding until the end product can be done by the CNC machines within the facility. The facility is capable of using not only glass but also advanced fibers like carbon and aramid together with polyester and epoxy resins. In the facility there is also a pultrusion line which enables to produce any kind of cross sections (I, U, L, O, etc.) up to 1000x300 mm continuously.

MİTAŞ will continue to provide services to all its customers by working on innovative composite products with its experienced staff in design, production and assembly, environmentally friendly technology, R&D and quality laboratory.

Production Methods

Filament Winding

It is a method of controlled winding of the impregnated fibers on the desired pattern, angle and thickness over a rotating mold, which was coated with a release agent. After the product is cured on the mold, it is extracted from the mold by a special machine. With this production method, it is possible to obtain very strong and high-quality products as the reinforcement rate is high. In addition, properties such as UV resistance, hardness and fire resistance of the product can be developed with the additions to the resin. Cylindrical or conical tubes and all other kinds of hollow profiles can be produced with this method. Fibers such as glass, carbon and aramid can be produced with resins such as polyester and epoxy.

Linear Pultrusion

It is the fastest production method in composites. It is the method of pulling glass, carbon or aramid fibers combined with polyester or epoxy resins within a hot mold. The product is cured shortly after it is pulled out of the mold. There is no length limitation in the end product and any kind of section allowed by the mold can be pulled continuously. High strength and high-quality products can also be obtained with this method.

Radius Pultrusion

It is a version of linear pultrusion by which profiles with a certain bending diameter can be produced. The products are released from the mold as already cured and curved with this method.

Pulwinding

Pulwinding is a combination of Filament Winding and Pultrusion methods. The products obtained as a result of this method have higher resistance. With this method, it is possible to obtain more slender but rigid sections.

Hand Lay-up

The simplest production method, the hand lay-up, is to place the fiber in the pre-prepared mold and then apply the resin onto the fiber with the brush until it reaches the desired thickness. Fibers such as glass, carbon or aramid, polyester and epoxy as resin can be used as reinforcement. At this stage, the required additives are added to the resin by taking into consideration the desired properties of the product as in the other methods. Fiber reinforcement ratios are lower than the above methods. It has a wide application area since it is possible to produce parts in almost every kind of geometry.

Vacuum Bagging

It is a method of emptying the remaining air inside the product which is closed with a vacuum bag and then obtaining higher quality products with the pressure applied as a result of the bag sticking to the surface of the product. In this method, parts can be produced in different geometries just like hand lay-up.
