Iranian Researchers Produce Prepregs, Epoxy Glass to Make Composites
Prepregs are pre-impregnated fabrics using a pre-defined resin system (usually epoxy). Prepregs are processed using vacuum, press and/or autoclave production techniques. Curing temperature and cycle will be defined by the resin system used (with a minimum of 80°C), an online research said.
“After several years of conducting research and development and the implementation of master's and PhD projects, with the cooperation of engineer Amirreza Poladvand, a PhD student of this research institute, we succeeded in extracting the technical knowhow of producing different types of these primers at a large scale,” Mohammad Hossein Beheshti, a professor at the Polymer and Petrochemical Institute of Iran and the manager of the prepregs project said, according to public relations department of the Iranian Ministry of Science, Higher Education.
He said that they produced epoxy primers of about 300 meters in length and one meter in width at the end of September 2022 in their company, adding, “The purpose of producing this product is to help the country's sensitive composite components production units and getting this product to the market.”
The researcher also said that manufacturers of composite products for both domestic and export applications can use these products in order to increase the quality of their products as well as accelerating their production process.
There are no limits regarding the type of fiber or the fabric, percentage of resin, and the technical team implementing this project can produce and supply all types of prepregs at a large scale, Beheshti further said.
The industrial production of phenolic glass prepregs was done a few years ago by a research team at the Composite Department of the Polymer and Petrochemical Institute, the report added.
