Suprem SA, a Swiss-based prepreg manufacturer, has reported a more than 50% annual growth in its business from prepregs made with Victrex PEEK polymer.
Suprems proprietary impregnation method allows for the rapid and flexible production of a variety of prepreg tapes optimized for automated processing equipment a key requirement for the cost effective mass production of composite parts for the aerospace and industrial markets.
Suprem have developed several options in fibre distribution across the section of a tape and adapted the surface qualities for the maximum energy absorbance offering higher design freedom for lighter weight and lower cost parts.
“”The excellent thermal stability and consistency of Victrex PEEK polymer enables Suprem to work with tight process controls in the impregnation process for unidirectional (UD) tapes to achieve the required processability and long-term performance,”” said Hansjrg Gysin, CEO Suprem SA.
Since the 1990s Victrex PEEK polymer powders and pellets have been used as a matrix material in the manufacture of advanced thermoplastic composite prepregs made of carbon, glass or aramid continuous fibres. Suprem is looking to develop applications in the future that use Victrex’s expertise in polyaryletherketones and other developments, such as VICTREX HT polymer for increased service temperatures and the reduced viscosity Victrex PEEK 90.
