In order to save additional weight and cost, Diab offers kits with multiple cores that can be customized according to loading requirements. You can also choose between a wide range of finishing options tailored to specific geometries and resin consumption requirements. 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.
