Honeycomb Core Production from Prepregs Based on Carbon, Glass, and Basalt Fibers Using Continuous Molding

Composite materials have excellent stress-related properties. At the same time, constructions made from them are lightweight and durable. To produce material based on the required structural properties, South Ural State University has proposed to regulate the mechanical characteristics of composites during manufacturing.

It is possible to optimize the characteristics of composites for production tasks using prepregs, i.e. semi-finished composite materials consisting of a fibrous reinforcing filler and a binder applied on both sides. Also, the technological option of changing the diameter of honeycomb core cells makes it possible to adjust the material properties. It is made from composite materials using expansion and embossing.

‘The technical peculiarity of this project is a fundamentally new approach to molding. We intend to organize a continuous process which significantly expands the scope of the composite materials studied,’ says Denis Vinnik, Doctor of Chemistry, Head of the Advanced Materials and Resource Saving Technologies of the Scientific Research Institute of SUSU (NRU), Head of the Department of Materials Science and Physical Chemistry of Materials.

The material will be used in the automotive and space industries.
