Diab Core Infusion blade concept

The DIAB Core infusion concept includes multiple core materials covering a wide range of mechanical properties. Below we illustrate what we believe are suitable core concepts for blades manufactured with DIAB infusion process. Using DIAB kits enables you to select an optimal core for your loading requirements, keeping cost and weight down. Further, you can also significantly improve lay-up time and blade quality using the DIAB kit process.

The Diab cores are available in a number of different finishing options particularly suited for wind blades. Using the appropriate finishing for curvature and resin consumption can also provide a considerable weight and cost reduction. 

Our Technical Services team and Composites Consulting Group (CCG) have a unique combination of practical and theoretical experience and can help you select the optimal combination of materials and finishing for your particular application.
