Abstract

This paper investigate the fracture toughness prediction of composite materials. A technique for monitoring and predicting the fracture point of composite materials is developed via experimental study. Samples of a composite approved for use in aerospace applications in accordance with EASA Part-145 are tested with a Zwick Z10 in order to determine the ultimate tensile strength. Several sample groups were introduced with the inclusion of size, production method, and lamination structure in order to identify any undue correlation. Data collected then analysed in order to identify the material nature. All information sets are used to identify the critical stress intensity factor, using a modified Griffith equation. Finally, this investigation present a full data set reflecting the fracture point of the material, which may be used for material selection reference purposes
