Summary

 

Composites 3 - AERO97048

Aims

Lifecycle assessment and recycling of composite materials

The overall aim of this course is to provide an understanding of lifecycle and recycling considerations related to the growing use of composite materials.

Joining and Repair of Fibre-Reinforced Plastics

To introduce the principles underlying joining and repair of fibre-reinforced plastics.

Laminate Analysis

Familiarisation with classical lamination theory and its application for predicting the deformation and strength of laminated composite plates. 

Design

This course aims at providing an introduction to general design approaches, with application to Composite Materials and Structures. There will be a review of particular issues in designing with composites, stressing interactions between materials, manufacturing & inspection, design and analysis. The course will introduce aspects linked with the Certification of Composites Civil Aircraft Structures and review Industrial Applications, with an emphasis on aircraft structures. 

Analytical Techniques

  • To develop a basic understanding of the main methods for organic materials characterisation  
  • To appreciate the type of information required to characterise organic materials. 
  • To appreciate the methods to characterise fibre and void volume fraction in composites. 
  • Understanding the principles and use of thermal analysis techniques for characterising polymeric materials. 
  • Introduction to methodology and tools for fractographic analysis 
  • Overview of basic translaminar, intralaminar and interlaminar failure modes 
  • Present case studies demonstrating methodologies and morphologies

Composites 1 - AERO97046

Aims

Introduction to Composites

To provide an overview of the science, technology and application of composite materials.

Fibres

  • To introduce the classification of fibres used as reinforcement in composites: natural an artificial fibres, metallic, polymeric, carbon, glass and ceramic fibres. 
  • To explain the distribution of strengths of fibres and introduce the concept of fibre bundle.  
  • To introduce the concept of fibre flexibility 
  • To present the processing, structure and properties of commonly available fibres.  
  • To consider the production of selected particulate and whisker reinforcements and the relative merits of different forms of reinforcement.  
  • To present the importance of control of the matrix-reinforcement interface 

Interfaces

  • To establish the basic principles of the theories of wetting and adhesion of materials. (This part of the course will also be relevant for the “Joining of Composites” lectures later in the course.)  
  • To show how the intrinsic interactions across the fibre/matrix interface may be modified. To show why such modifications are undertaken in industry.   
  • To show how the “strength” of the fibre/matrix interface can be measured and related to the nature of the interfacial interactions.  
  • To examine the effect that the nature of the fibre/matrix interface has upon the presence of the fibre/composite material.  

Ceramic/Metal/Polymer Matrix

• To introduce the development of ceramic matrix composites (CMCs)  
• To present the different polycrystalline ceramic and silicate glass matrix available for CMCs 
• To consider relevant process technologies for reliable production of CMCs  
• To enhance understanding of the structure and mechanical properties of CMCs by considering particle and fibre reinforced composites, toughening mechanisms, failure behaviour and high-temperature behaviour, including thermal shock.  
• To illustrate application of ceramic matrix composite materials with selected examples of commercially available composites.  
• To address limitations of available CMCs

• To introduce the variety and typical applications of metal matrix composites (MMCs) 
• To deliver an overview of MMC technologies; benefits and limitations, 
• To consider processing methods for different MMCs and factors affecting their manufacture. 
• To review typical behaviours and failure modes of the main MMC classes. 

• To introduce polymer-basics: chemistry, physics, classification, structure, molecular weight (distribution). 
• To present the difference between: a) chain growth & step growth polymerisation, b) amorphous & semi-crystalline polymers, c) thermoplasts & cross-linked polymers. 
• To present polymer properties: thermal (melting temperature, glass transition temperature), crystallinity: dependency on structure. 
• To illustrate mechanical properties: stress-strain behaviour, Young`s modulus. 
• To introduce viscoelasticity: models, time-temperature-superposition. 
• To address an example of polymer-matrix-composite

Role

Lecturer

Advanced Manufacturing - AERO96020

Aims

The aim of this module is to introduce the manufacturing processes of composite materials and their corresponding underlying manufacturing principles to provide a deeper understanding of the relationship between design, manufacturing processing and materials properties. This module discusses basic transport equations and constitutive laws used in composite processing, followed by detailed quantitative/qualitative discussion and analytical analysis of polymer matrix, metal matrix and ceramic matrix composite manufacturing. Various composite manufacturing methods are discussed, including short polymer fibre composites, advanced thermoplastic composites, advanced thermoset composites, melt metallurgical processes, powder metallurgical processes, advanced hybrid fibre metal laminates and ceramic matrix composite manufacturing route via melt infiltration, chemical vapour infiltration and polymer impregnation and pyrolysis processes. The real life applications of each manufacturing processes are also covered in this module. The module will consist of timetabled lectures deliver by two academics with the relevant research expertise.
