In order to be eligible for a second cycle course the applicant needs to fulfil the general and specific entry requirements of the programme that owns the course. (If the second cycle course is owned by a first cycle programme, second cycle entry requirements apply.)
Exemption from the eligibility requirement:
Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling these requirements.
Course specific prerequisites
Courses in chemical and mechanical engineering.
The aim of this course is for the students to gain knowledge of biopolymers and biocomposites which are used as structural materials. The intention of this course is to bridge gap between biology, physics and chemistry and therefor this course is suitable for chemists, biologists and material scientists. In the course we present biologist's analysis of structural material of organisms, using molecular biology as astarting point. We will explore the chemical structure of biopolymers, illustrating how they composition determine mechanical properties of the materials in which they occur - including skin, artery, plant tissue, stiff composites such as insect cuticle and wood, and biological ceramics such as teefth, bone and egg-shell. Finally we will discuss with students how the design from nature with biomimicry can be applied in developing new "intelligent" materials.
Learning outcomes (after completion of the course the student should be able to)
- Cite the four components that are involved in the design, production, and utilization of various material classes
- List the differences between material properties of biological materials, polymers, ceramics and metals
- Describe a typical polymer molecule in terms of its chain structure
- List differences between structure of synthetic polymers and biopolymers
- Understand what determines the structure and properties of proteins
- List the major functions of proteins and list the most important structural proteins
- Compare major differences between structure and proteins and polysaccharides
- Understand biosynthesis and assembly process of cellulose and secondary cell wall
- Understand the basis of elastic and viscous properties of materials and list viscous Newtonian properties of different substances
- Describe the basic mechanical models for linear viscoelastic response
- Explain creep and stress-relaxation by using Mawell and/or Voigt-Kelvin elements and their combination and relate the response with the molecular response mechanisms in polymers
- Predict either viscous or elastic response of materials based upon the concept of the Deborah Number
- Describe the principles of Dynamic Mechanical Testing and its application in creep and stress relaxation experiments
- Explain the meaning of storage modulus, loss modulus, their relation with elastic and viscous properties of materials and damping
- Understand the principle of the Time-Temperature Superposition concept and its application to predict mechanical response of polymeric materials
- Relate the molecular structure of polymers with their viscoelastic response
- List the mechanical test used to assess the end use and the mechanical properties of polymeric materials
- Perform the mechanical testing of biological and polymeric materials and evaluate data
- Understand the fracture mechanics of biological materials
- Describe the mechanism of reinforcement in man-made and biological composites
- Relate the structure and composition of biological materials with their mechanical properties and the significance for biological inspired engineering materials and biomimetics.
Many material systems found in nature exhibit a combination of properties that is not found in synthetic systems. The unique performance of natural materials arises from precise hierarchial organization over a large range of length scales. These materials display unique properties that are affected by structure and generative processes at all levels of the biological structural hierarchy. The following subjects will be discussed in lectures.
- Biomechanical properties of biological materials
- Experimental tools for determining structure of biological materials
- Fracture mechanics, prediction of failure
- Biopolymers: Proteins
- Biopolymers: Polysaccharides
- Biofabrication. Biogenesis, enzymes and cells at work
- Biomimetic material design
In addition to series of lectures students will participate in projects in which they will make experiments with biological materials such as wood, shells, mussel adhesives, spider silk, bones etc
