Full text

Abstract:

Fibrous composites, having excellent mechanical properties in the direction of the fibres, have lower mechanical properties in the through thickness direction, controlled by resin. Z-pinning improves the delamination toughness (up to 500%) with a relatively modest reduction to the in-plane mechanical properties (typically 5-15%). This experimental study investigates the mechanical performance of Z-Pins bridging an existing delamination in fibre reinforced resin composites under pull-out (Mode I), shear-out (Mode II) and mixed mode loading conditions using a specially designed testing rig.

Abstract:

Z-pinning is a through-thickness reinforcement technology for polymer composite materials that has been developed and commercialised over the past fifteen years. The through-thickness reinforcement of composites with thin metallic or fibrous pins aids in suppressing delamination, improving impact damage tolerance and increasing joint strength. Z-pins are applied to the composite part during its manufacture. Pins are embedded within sheets of foam and placed over the unconsolidated part. Subsequently, the foam is compacted and the pins transferred into the part, which is usually an uncured pr

Abstract:

Effective treatment of carbon fiber components to improve delamination resistance is vital to the application of such materials since delamination is one of the biggest concerns regarding the use of composites in the aerospace sector. Due to the significant application benefit gained from increased stiffness to density ratio with composite materials, innovative developments resulting in improved through-thickness strength have been on the rise. The inherent anisotropy of composite materials results in an added difficulty in designing structural elements that make use of such materials. Propose

Abstract:

Sandwich structure is one type of composite materials that has been widely used in automotive, marine and aerospace structures. It offers high specific modulus and specific strength. Sandwich structures consist of two thin face plates that enclose a thick core. The face plate is generally stiff enough to resist bending load, whilst the foam core is of lower modulus, lightweight yet it can transfer the shear and compressive loadings. Sandwich structures with composite faces have been applied to fabricate aerospace structures (e.g., engine cowling, floor panels, etc.) because of their excellent

Abstract:

This thesis describes specific new applications of Z-Fibre ® pinning and focuses the attention onto the failure modes of locally reinforced (z-pinned) structures. Design implications of the use of localised reinforcement on structures, rather than laboratory coupons, are considered. Z-pinning reinforcement is applied to cylindrical crash tubes and I-section patch joints manufactured from woven carbon / epoxy pre-pregs. Z-pinning is shown to improve the Specific Energy Absorption (SEA) of the crash tubes by up to 76 %, the exact amount depending on the tube geometry. For the I-section patch joi

Abstract:

Il numero di casi riguardanti patologie neurodegenerative che colpiscono il sistema nervoso centrale sotto forma di demenza aumenta di anno in anno. Si ha quindi la necessità di individuare la presenza della malattia non solo a livello qualitativo, ovvero tramite la sola diagnosi del medico, ma anche a livello quantitativo, cercando di elaborare un metodo di analisi che tenga conto della variabilità tra individuo e individuo, ma che rimanga applicabile per la maggior parte della popolazione. In questo lavoro di tesi sono stati utilizzati due metodi di analisi statistica di immagini PET cerebra

L'amplitude du processus etudie (l'annihilation d'une paire electron-positron en un z qui se desintegre en une paire de leptons tau) est fonction des constantes des couplages vectoriel et vectoriel-axial, dont le rapport depend quadratiquement de la masse du top.

Celé riadenie motora je navrhnuté v prostredí Matlab-Simulink technikou nazývanou návrh systému z modelu. Následne pomocou automatického generovania kódu bol získaný zdrojový kód, ktorý bol použitý v reálnom aktuátore a odtestovaný v reálnych podmienkach.

Abstract:

The bearing behavior of bolted composite joints is significantly poorer than that of their metallic counterparts. The objective of the present study was to examine ways of improving the bearing performance of bolted joints in carbon fibre reinforced epoxy laminates. Two strategies were examined, namely stiffening of the matrix using nanofillers and through- thickness reinforcement of the laminates using z- pins. The development of a nanoparticle reinforced matrix resin, and its performance in a composite loaded in bearing, was the focus of the first part of the study. A commercial nanoclay, I3
