Composite Stiffened Panel Optimisation

 

2013-2015: Aero Optimal developed the first analytical optimisation tool for CFRP stiffened panels typically used in large CAT "A" composite structures. This innovation facilitated the creation of minimum weight structures for multiple criteria in stiffness, strength, stability, and damage tolerance. However, over-design due to damage tolerance criteria dominating the design drive for CFRP panels was a key concern, hence the subject of several Aero Optimal study proposals.

2016-2019: Aero Optimal proposal to Innovate-UK to complete the Analytical Optimisation Tool Damage Tolerance Module Adapted for Graphene Enhanced Composite stringer stiffened Aero-structures panels.

 

Aero Optimal believed that the solution was to develop an analytical method for high accuracy in predicting the dynamic response of impact damage.  Updating this criterion as a responsive damage tolerance module to the software tool allows engineers to enhance failure prediction accuracy and negate the need for unnecessary sizable expensive, and time-consuming tests.

 

2019-2020: Analytical Prediction of Impact damage on Stiffened Composite Panels

Within this study, the effect of variable stiffness distribution due to the stringer presence with various layups was investigated for panel-stringer laminate under impact loading. Analytical models from a typical skin-stringers assembly were developed based on a spring-mass system to predict the dynamic behaviour of the striker-plate domain and finally, determine the contact force history.  Comparison with experimental and Finite Element results that the model developed proved to successfully predict the response of stringer stiffened composite panels with a range of layups and geometry designs under low-velocity impact loading conditions.
