OPTIMAT BLADES Informe resumido

Design recommendations for next generation of rotor blades

The OPTIMAT research programme is an extensive material testing program that has conducted over 3000 individual tests over four years. The testing focus has been on the mechanical properties of the composite materials commonly used in modern wind turbine blades, specifically epoxy GFRP. This report aims to analyse the key research outcomes of the OPTIMAT research programme, and provide a summary of these key findings in the context of practical design guidance.

The TG6 work captured in this report has reviewed all of the work conducted throughout OPTIMAT and summarised this in the context of practical applications in design for industry.

As part of this review, the following key areas were reviewed: test coupon selection, stiffness assessment, S-N curve development, Constant Life Diagrams, rain flow counting, strain rate effects, variable amplitude loading, complex stress states, extreme conditions, thick laminates and repairs, residual strength, and the use of OptiDAT data in design.

The current industry approach, the key OPTIMAT observations, and new perspectives have been identified for each of these areas.

In all, 39 design recommendations have been developed in the following key areas: life time prediction, complex loading, residual strength, extreme conditions, and repair. These design recommendations will be considered for inclusion of the next version of DNV/GL design guidelines.
