Project manager of PRELUDE 5 Project

Mar. 2014 – May 2016 

I was a project manager of PRELUDE 5 Research Project funded by the National Science Centre of Poland; “Detection and evaluation of the delamination in multilayered composite structures by Active Infrared Thermography”, Contract no UMO-2013/09/N/ST8/04360, 06.03.2014 - 06.05.2016.

As a project manager, I was responsible for devising the research conception, the schedule and the project plan execution in accordance with the contract. I supervised and cooperated with mechanical, material science and electrical engineers as well as external institutions and companies. Specific research aims of the project required from me performing the following tasks:

– Research material design and the manufacture process supervision. It was one of the key components of the project. Specimens were made of two types of materials: woven glass fabric with epoxy resin and Hexcel TVR 380 M12/R-glass unidirectional prepreg layers. Excellent quality of investigated components was ensured by the autoclave manufacture system. For the comparison, a standard vacuum bag and oven were used for sample preparation. The different directional characteristics were tailored in order to obtain high mechanical properties, mainly, specific strength and stiffness. The laminates were also produced with artificial delaminations on the edges of individual material layers in order to investigate their influence on the thermo-mechanical behaviour of structures. The novel delamination standard in the form of the void of pre-defined geometry and thermal properties within the composite structure was constructed and used in testing as the reference standard.

– Research method optimizing. The following Active Infrared Thermography analysis parameters were determined: thermal pulse shape, the emissivity of investigated surface samples, homogeneity of heat excitation, environment conditions, research equipment positioning, signal sample frequency, data-time correlation optimizing.

– Composite structures experimental research. Plates and curved components with artificial and real delaminations were analysed thermographically and mechanically. The aims of the study were to determine detection, localisation as well as quantification and development evaluation of defects in multilayered composite structures.

– Numerical Finite Element analysis. Transient heat transfer and mechanical analyses were performed for 2D and 3D models of composite structures with various embedded defects in order to investigate their influence on the thermal and mechanical structure behaviour. All of the FE simulations were carried out with the use of the commercially available numerical ANSYS package.

– Appropriate scientific journals selection for study results publication. It required data analysis and evaluation, comparison between experimental and numerical results, drawing conclusions.

PARTICULAR ACHIEVEMENTS

Constructed, tested and patented the novel delamination standard in the form of a pre-defined 10-micrometre void geometry and thermal properties within the curved multilayered composite structures.
