Urlings, A.P.C. (author)
The goal of this research was to get a better understanding of the consequences of the integration of a battery electric powertrain on the chassis layout and its type approval in the European Union. The Roding Roadster was used as reference throughout this research. Based on the legislation for type approval within the European Union,...

Tonnaer, R. (author)
The strict quality requirements for aerospace composite structures give rise to costly quality control procedures. In automated fibre placement (AFP) these procedures rely heavily on manualwork and inspection. This research aims at performing preventative non-destructive evaluation of composite laminate quality based on an online geometric...

Liu, L. (author)
A one-dimensional analytical solution to predict buckling-induced delamination growth was developed toward an efficient and effective engineering application. The postbuckling solution for a composite beam was first obtained with nonlinear deflection approximations based on 'thin film' assumption. An interlaminar stress analysis method was then...

Groeneboom, B. (author)
AE-based structural integrity monitoring of composite structures potentially offers the means to gain knowledge on in-service damage accumulation, as well as mitigation of some of the risks associated with in-service damage. However, validation of any identified classes of AE events with regard to their underlying source mechanics is generally...

In aerospace industry, composites structures are widely used because of their high stiffness to weight ratio. To ease the manufacturing process, components are assembled together using fasteners which leads to introduction of holes in composites. The failure of these composite structures is affected the high stress concentration region around...

Even though composite materials are being applied more and more often, these materials are often not used to their full potential. In particular, composite materials are very sensitive to Compression-After-Impact (CAI), typically leading to knockdown factors in the order of 0.65. Many researchers have tried to predict the effects of Compression...

Research into the fusion bonding of joints containing thermoplastic and/or thermoset composites. A thermoplastic interlayer is co-cured with the thermoset that provides a fusible surface. Depending on the type of materials the interlayer can form an adhesive interface or a gradient interphase with the thermoset. Welding of thermoset composite to...

This thesis continues the work performed by Ferreira and Almeida on the topic of weight and cost reduction of composite multi-spar torsion-bending boxes. The goal is to find the influence of changes to the structural configuration on the resulting weight of said torsion-bending boxes. Using analytical methods, combined into the BoxSolver MATLAB...

Subramanian, K. (author)
The high stiffness to weight ratio of fibre reinforced composites have been utilized in improving the performance of various structures conventionally designed using metals. One such application is the gangway of the Ampelmann system used to transfer personnel safely from and to the offshore platform in sea. In the current work, a preliminary...

Accurate thermal characterisation of composite structures can help structural designers in predicting thermal paths in a spacecraft structure and assessing the effect of modifying materials on the structure’s overall thermal performance. Existing spacecraft thermal analysis software lack the ability to model anisotropic thermal properties of...

This paper introduces a new type of peel tests dedicated to composite bonding: Composite Peel Tests. This test is inspired on the standard floating roller peel test widely used for metal bonding. The aim of this study is to investigate the potential of the Composite Peel Test to assess interface adhesion in composite bonded structures. To this...

Kosmas, N. (author)
In design with composite materials, the capability of tailoring the properties of the structure with respect to the specific load requirements in each direction, allowed by their anisotropic nature, is coupled with the development of interlaminar stresses transferred through the thickness. Specifically, at the free edge of the laminate, due to...

Shi, H. (author)
Compared to thermoset composites, thermoplastic composites are drawing more and more attention by aircraft industries not only due to their excellent material properties but also due to their potentials to reduce cycle time and structure cost by using low-cost manufacturing technologies such as welding. Resistance welding has been regarded as...

Dillinger, J.K.S. (author)
The application of composite material in load carrying structural components of an aircraft is rapidly gaining momentum. While part of the reason for this can certainly be attributed to an increasing confidence of designers in the new material as a result of growing experience, two other crucial points can be made. One, the continuous...

Van der Vossen, B.C.W. (author)
Modern and future aerospace structures make increasing use of fiber reinforced composite materials to optimize structural performance. Yet, characterizing the composite material properties is very expensive and time consuming. Parameters like non-linear shear and their interactions with stresses perpendicular to the fiber direction are hardly...

Cui, H. (author)
Composites are increasingly being used in aerospace, automotive and other industries. The T-joint (also named stringer stiffened skin) is a typical connection, broadly used in thin-walled structures, such as the wing and fuselage of aircraft. This thesis presents the analysis of the delamination and debonding failure of laminated composite T...

Nagelsmit, M.H. (author)
Composites are notorious for their poor impact behaviour. Delaminations seriously decrease the compressive strength of the material after impact. Laminates made from woven fabric show in general more beneficial impact behaviour than laminates with unidirectional layers, but their manufacturing process is harder to automate. The new fibre...

This paper demonstrates that existing Structural Health Monitoring (SHM) techniques have potential during the production phase in addition to their application for maintenance and for in-flight monitoring. Flaws occur during composite fabrication in industry, due to an imperfect process control and human errors. This decreases production...
