Abstract
Light resin transfer moulding (LRTM) has been developed as an alternative to vacuum infusion (VI) but a direct comparison between the two processes is needed to quantify any advantages. This paper uses a technical cost model and an empirical study to show the potential financial and performance benefits of LRTM for manufacture of a generic 40 m wind turbine blade shell. The use of LRTM when compared to VI demonstrated a possible 3% cost saving, improved dimensional stability (5.5%), and reductions in resin wastage (3%) and infusion time (25%). A decrease in internal void formation (0.9%) resulted in an increase in mechanical performance (<4%) for LRTM moulded parts.
