Development of preform concepts to optimise local load transfer points for a space application, validated in a resin transfer moulding technology

Abstract

The objective of the thesis is to develop new design concepts or dry textile preforms, which are implemented in a new concept to enhance the performance of a local load transfer point, the T-joint. Therefore, the present occurrent failure modes have to be identified to define reasonable fibre architectures for the concepts. To meet the requirements on the T-section, all textile-processing techniques have to be screened. As a result, a wide spectrum of opportunities will be given to provide a wide base for determination. To compare the variety of given concepts, relevant criteria have to be defined and weighted to contrast them in a decision matrix. Moreover, the most promising concepts have to be validated physically to underline and intensify the informational value of the previously gained results. The comparison to a referring structure will demonstrate the achieved performance of the new concepts. Concurrent to the evaluation of the concepts, the manufacturing processes, as preforming and consolidation or resin infusion have to be customised to the new preform concepts.
