A fast procedure for the design of composite stiffened panels
AbstractThis paper describes the analysis and the minimum weight optimisation of a fuselage composite stiffened panel made from carbon/epoxy material and stiffened by five omega stringers. The panel investigated inside the European project MAAXIMUS is studied using a fast tool, which relies on a semi-analytical procedure for the analysis and on genetic

Degradation investigation in a postbuckling composite stiffened fuselage panel [PDF]
COCOMAT is a four-year project under the European Commission 6th Framework Programme that aims to exploit the large strength reserves of composite structures through a more accurate prediction of collapse. Accordingly, one of the COCOMAT work packages involves the design of test panels with a focus on investigating the progression of composite damage ...

Combined structural and manufacturing optimization of stiffened composite panels [PDF]
Manufacturing considerations have been incorporated into the design optimization of a blade-stiffened composite panel. For the manufacturing analysis, a one-dimensional resin film infusion model is developed to compute the infiltration time of the resin into a fabric preform of the panel.

Computational Analysis of Compressed Stiffened Composite Panels with Impact Damage
A complex modeling technique is presented in this paper for a numerical analysis of compressed stiffened composite panels with impact damage. The numerical technique is based on the LS-Dyna code application, which simulates both the dynamic deformation ...

Vibro-Acoustic Modelling of Aeronautical Panels Reinforced by Unconventional Stiffeners
The purpose of this work is to characterise the vibro-acoustic behaviour of rectangular flat panels reinforced by “unconventional” stiffeners. Such panels are being increasingly employed in the aircraft industry in the case of composite fuselage, so that

Effect of Forming Process on Compression Characteristics of Composite Hat-stiffened Panels
An experiment was conducted for the composite hat-stiffened panels with different forming process types with boundary constraint, in order to study the effect of secondary bonding and co-curing on the compression stability and carrying capacity of ...

Structural Efficiency of Stitched Rod-Stiffened Composite Panels with Stiffener Crippling [PDF]
The structural efficiency of rod-stiffened stitched specimens is evaluated to determine their weight saving potential if the stiffeners were allowed to buckle at less than or equal to design ultimate load. Analytical and experimental results from rod-stiffened and blade-stiffened single-stiffener specimens are presented. In both cases, skin and flanges

Debonding between flange and skin is the dominate failure mode of stiffened composite panels which are widely used in modern aircraft. The influence of internal cladding layer in hat stringer on the onset of debonding is investigated experimentally and ...
