Zur Notwendigkeit eines konstruktionsmethodischen Ansatzes für die zeitfeste Auslegung endlosfaserverstärkter Kunststoffbauteile

Abstract

Efficient and systematic design methods are indispensable aids on the way to effective lightweight solutions. In this article. the necessity of providing the product developer with a design method for the design of endless fibre-reinforced plastic [FRP] components to fulfil fatigue requirements is highlighted. Existing damage models and test methods could be used and extended within such approaches. A suitable method should take into account particularly the variety of requirements for FRP components and consider other influences. e.g. from multi-layer composite design or load introduction. preferably supported by CAE tools. The simple applicability of an effective approach should be demonstrated both on test specimens and on demonstrator components.
