TY - CHAP A1 - Stark, Wolfgang A1 - Bohmeyer, W. A2 - Karbhari, V.M. T1 - Non-destructive evaluation (NDE) of composites: using ultrasound to monitor the curing of composites T2 - Non-destructive evaluation (NDE) of polymer matrix composites - Techniques and applications N2 - Typical composite materials for lightweight construction consist of a fibre (glass or carbon) reinforced thermosetting matrix. The impregnation of the fabric is made with liquid resin – usually epoxy resin or unsaturated polyester resin are used. The main processing methods are resin transfer moulding (RTM) and prepreg technology often used in combination with autoclave curing. After shaping, the resin must be cured. The final properties of the produced parts depend on the curing degree and the final glass transition temperature. Analytical methods and the use of ultrasound for online cure monitoring in the manufacturing process are introduced. Examples for the application of ultrasonic cure monitoring for the production of composite parts for traffic systems are also covered.
