Composite - material of the future

Our basic manufacturing material is composite. A composite material is made by man, not by nature, although it may include natural intermediates (e.g. wood). It is made of at least two chemically different materials (matrix and reinforcing phase), which must be connected in a continuous manner, while maintaining the borders of the two materials. As the Wit-Composites, we mainly produce polymer-fiber composites, using preimpregnated fabrics.

In the production process of polymer-fiber composites we use among other things, the method of autoclaving, infusion and vacuum bagging. Next to the most widely used contact forming, allowing for quick start of production in small quantities, we use the vacuum methods, the winding methods, pressure methods using an autoclave and pre-impregnated fabrics, so that we get the products of very high quality and repeatability. The use of composites in industry increases permanently, primarily in order to reduce weight, improve safety, and to change the material properties, which is related to the economics of use. Many branches of industry are using currently the growing family of composite materials.

Three advantages of the composite

stiffness

- composite, due to its characteristics, can be formed in any shape and after curing exhibit high stiffness

lightness

- anything made of composite will be of the lowest possible weight

strength

- composite guarantees that the manufactured products will not be susceptible to stretching and bending, and yet be stiff and light

Technology of the future

lightness, strength and durability
