Research interests:聽My research interests include the manufacture and performance prediction of durability-enhanced thermoplastic composites for marine, transport, and sporting goods applications. The virtually unlimited potential for design tailoring and unexplored processing, repair and recycling opportunities make thermoplastic laminates an exciting area of research. More computing power, new materials and novel requirements have seen performance prediction adoption in new markets, opening up new challenges for researchers to develop advanced explicit dynamics (time-dependant) simulations with continuum damage and user-material models to investigate the impact durability of thick laminates and coupled finite element analysis-computational fluid dynamics to explore underwater impacts. Designing experiments that help verify these predictions has been one of my most rewarding practical challenges to date.

Project Title:聽CT inspection of bonded composite repairs
Abstract:聽Florian is an exchange research student from the Polymer Competence Center Leoben located in Leoben, Austria. His main area of research is repair of composites by adhesive bonding, which is of high interest for the aircraft industry. This interest is related to the fact that an increasing amount of structural components used in modern civil aircraft are constructed using composite materials. The scope of the research activities performed during the exchange is the investigation of damage mechanisms in repaired composite specimens that were subjected to impact loads with well-defined energy levels. For this purpose, damaged as well as pristine specimens will be inspected using high resolution computed tomography.

Project Title:聽Performance monitor and prediction of a biaxially loaded thin composite tube
Abstract:聽The objective of this project was to study the behaviour of composite drive shaft. Therefore, I have concentrated on cylindrical specimens, manufactured using the automated fibre placement technique (AFP), under combined loading. During this internship, I was involved in a range of analytical and experimental activities related to biaxial testing of composite cylindrical specimens with cut out. A FEA has been carried out for the prepared specimens to predict strain and failure under combined loading. Besides, some analytical calculation have been made, including dimensioning calculations of a conventional drive shaft in order to compare with the performance of a composite drive shaft. After the analytical step, the experimental investigation has been carried out using an Instron biaxial testing machine. Digital Image Correlation (DIC) and Distributed Fibre Optic Sensing (DFOS) has been used to acquire strain fields on cylindrical specimens.

Project Title:聽Optimisation of Advanced Grid Structure Based on Automated Fibre Placement
Abstract:聽Advanced grid structure (AGS) has been regarded as one of the most common composite structures. This project aims at the optimisation design and automated manufacture of a novel grid structure with significantly improved structural efficiency. The deformation mechanism of fibres around intersection region of crossed grids will be analysed considering compaction of fibre bed and flowing of resin. Moreover, the relationship between fibre distribution and the mechanical properties of composite structure will be studied in theoretical and experimental method. A universal criterion will be proposed to reduce processing defects and optimise the intersection region of AGS, based on automated fibre placement process. The success of this research will provide theoretical foundation and technical reference for the design and manufacture of high performance advanced composite grid structures, to meet requirements of lightweight and extreme service conditions.

Project Title:聽Automated Manufacture of a Shape-Adaptive Large Hydrofoils
Abstract:聽In this work was presented the design and manufacture of a shape-adaptive large hydrofoil of 1.5 m long using the automated fibre placement technique (AFP). To determine the optimum layup of the laminate, a coupled FEM code with a Genetic Algorithm was used. With this method, the goal was to obtain the different ply orientation to achieve the required bend/twist capability of the large hydrofoil. Once the optimization phase was completed, the resulting layup orientation was used in the development of the G-code and proceeded with the manufacturing of the laminate using the AFP technique. During the automated lamination, it was implanted an embedded optic fibre as a monitor control system. After the curing process, the laminate will be submitted to fatigue loads and measure the mechanical response. The results obtained will be compared to experiments made on laminates with similar characteristics built with classic manufacturing process (RTM).

Project Title:聽Evaluation of the influence of hoop fiber to axial fiber ratio (H / A) on the amount of absorbed energy in the process of the axisymmetric tube compression in dynamic conditions.
Abstract:聽Recently, there has been considerable interest to incorporate composite crashworthy structures in the aerospace and automotive industries. Crashworthiness is typically defined as the ability of a structure to absorb energy in a collision or an impact, and survive; in the case of a passenger vehicle, this would be the ability to ensure the survivability of the occupants. Well-designed composite crush structures can absorb significantly more energy per unit mass than metals. The crushing tests of samples with use of various hoop fiber to axial fiber ratio in dynamic conditions are planned in this work. Unidirectional prepreg and plain carbon prepregs of various weights will be used in the study. Made research may allow for significantly increasing in transport safety.

Project Title:聽Characterization of the influence of placement rate on the mechanical properties of laser-assisted AFP composite laminates by means of in-situ mircoCT compression tests.
Abstract:聽Automated Fiber Placement (AFP) of composite materials has great potential to become an manufacturing technology for components of high volume applications. Parts of thermoplastic composites can be fully processed with this technology by in-situ consolidation of the material via laser heating. This ability to manufacture composite parts without an out-of-autoclave (OOA) process potentially saves high running and capital costs that are associated with autoclaves. However, to obtain autoclave-level mechanical properties via AFP is still challenging. In this study unidirectional carbon-fiber-reinforced PEEK laminates, manufactured by laser-assisted AFP with different placement rates, are compared. The mechanical behavior of the composite laminates are analyzed by means of in-situ microCT compression tests. The focus of these measurements is especially on the distribution and geometry of the voids within the material and the failure initiation under compression.

Project Title:聽Heating characteristics of laser assisted Thermoplastic-Automated Fiber Placement of 3D paths
Abstract:聽Thermoplastic Automated Fiber Placement (TP AFP) is a fully automated process to manufacture high performance composite parts. The thermoplastic matrix offers unique properties to the composite part, but also requires special manufacturing process knowledge. The ultimate goal of TP AFP process development is reaching sound in situ consolidation, as this reduces manufacturing steps and costs. However, today the TP AFP process is limited to flat parts or geometries with either constant or a very soft curvature. The work focuses on characterizing the laser heating characteristics of convex 3D geometries with a small corner radius. A thermal model of the process is accompanied by lay up trials with a state-of-the-art TP AFP machine on 3D geometry.
