B-PREG

About This Project

B-PREG develops and manufactures natural fiber-reinforced thermoplastic composite materials aimed at lightweighting vehicles in the automotive industry.
Reducing fuel consumption and CO₂ emissions, as well as extending the range of electric vehicles, has made lightweighting one of the most critical focus areas in automotive design. The industry is constantly seeking lighter and thinner materials that still meet high mechanical and acoustic performance requirements.

B-PREG Kompozit ve Tekstil A.Ş. has developed a truly novel material—the first of its kind in Turkey, and among the few globally: a natural fiber-reinforced unidirectional thermoplastic prepreg.
Offering superior mechanical and acoustic performance, B-PREG is significantly lighter and thinner than conventional alternatives. Thanks to its natural composition, it is also highly eco-friendly.

Currently, natural fiber materials in vehicles are used mostly in the form of felt or wood-dust composites for interior trim parts. In comparative trials, panels made with B-PREG achieved up to 70% weight reduction over these existing materials. What’s more, B-PREG panels—only 3 mm thick—demonstrated over 40 dB sound transmission loss, a level of acoustic insulation that stands out in the automotive field.

Initial production tests show that B-PREG is highly compatible with existing automotive manufacturing processes. OEMs can adopt the material without significant capital investment or major changes to their current production lines.

The material’s mechanical performance is also highly promising. While tests so far have focused on car interior trim applications, the company plans to explore B-PREG as an alternative to sheet metal in the near future.

Bus manufacturers are also showing strong interest. They are preparing to test B-PREG for floor, roof, and side panels—applications that require thinner and lighter materials without compromising on durability or performance.
