It surprises me that only few articles are available. Here's another interesting paper: http://paginas.fe.up.pt/demegi/Avaliacao/Pp_Camanho_Mathews_99.pdf? Professor Matthews did quite some work on composite joints a good reference is: Matthews, F. L. Joining fibre-reinforced plastics / 1987 Tom

For metallic lugs design guidelines are available (eg. Niu). However, these can not be directly used in composite lugs. Does anybody know of design guidelines or methods to analyze composite lug? I am analyzing a 3D composite (carbon/epoxy) lug. This thick laminated lug (17.5 mm) has a hole...

Thanks for your inputs! The Material Specification SM_5H_satin_AIMS_05-04-009 defines the requirements for the Standard modulus carbon fibre fabric, 5H satin, 370 g/m² (with or without binder) and toghether with the RTM6 liquid epoxy resin (180°C cure), this material is qualified for aerospace...

RPstress, thanks for your advice. We'll run a damage/strength(!) FE for this material with a virtual textile simulating software. Regards, Tom.

I am analyzing a composite (carbon/epoxy) component. For the Hashin-fabric failure criterion (see attachment), some out of plane properties are needed. We do not have time for coupon testing. Specific materials are: - Standard Modulus Carbon fibre fabric 5H Satin 370 g/m² - Liquid Epoxy Resin...
