Conference on Composite materials for structural performance: towards higher limits, Roskilde, Denmark
5 September 2011 - 5 September 2011
Denmark
A conference on Composite materials for structural performance: towards higher limits will take place from 5 to 9 September 2011 in Roskilde, Denmark.
Today, most wind turbine blades are made of composite materials. Composite materials are based on plastic reinforced with long aligned fibres, which are made of either glass, carbon, kevlar or other strong materials. The fibres are arranged in layers on top of each other and are kept together by the plastic, which is also called a matrix. The strength and durability of the components depend on the properties of the materials and on the design methods and criteria used for designing the components. Similarly, composite materials are used for other large constructions such as ships and aircrafts..
There is a great need in industry for improving the properties of composite materials, e.g. for developing materials equally strong, but considerably lighter in order to save energy and increase cost-effectiveness. Design limits e.g. criteria for materials failure and lifetime predictions can be expanded by developing and validating improved models for the critical limit states, e.g. the onset of fatigue failure under multiaxial stress state, the use of damage tolerant design approach and the use of more advanced modelling tools such as cohesive zone modelling.
The focus of the conference is to increase the strength and durability of composite materials by providing a better understanding of the properties of composite materials, right down to micro scale.For further information, please visit: http://www.risoe.dtu.dk/News_archives/News/2011/0228_32_Materialesymp.aspx?sc_lang=en(opens in new window)
