Development of Infusion Technology for Thermoplastic Composites with PMMA Matrix

Article Preview

Abstract:

The paper presents the development of vacuum infusion technology for thermoplastic composites with a polymethyl methacrylate (PMMA) matrix and continuous fibre reinforcement. The study focuses on process optimization, including testing of various tool surface treatments, adjustment of infusion parameters, and modifications to the technological lay-up. Additionally, the influence of sampling location within the composite panels on test results was examined. Differences in thickness, glass transition temperature, and in-plane shear strength were observed between the different sections of the panels. High-quality impregnation of glass fabrics was achieved, and the feasibility of manufacturing functional demonstrators with complex geometries was verified. The findings confirm the potential suitability of PMMA-based composites for aerospace applications.
