Description

This unit will introduce a wide range of solutions and principles found in nature, e.g. biological ceramic, polymer, elastomeric and cellular materials, nature's approach to building with fibres, attachment methods in nature, structural adaptivity and functional biological materials. The unit will be delivered from a materials science perspective with particular emphasis on the application of these methodologies to advanced fibre reinforced polymer composites. The specialist knowledge and understanding gained through this unit will provide the students with a good foundation for further research in this field.

The aim of this unit is to:

  • Provide the students with an overview of the structure-function relationship of natural materials as a model for the development of new types of high-performance engineering materials.
  • Introduce a range of composites materials that can be found or are inspired by nature, or that make use of naturally occurring components to enhance their functionality.

Intended learning outcomes

Upon successful completion of the unit students will be able to:

  1. Provide a clear overview of the diverse range of nature's materials, their complex hierarchical structure and describe their unique engineering properties.
  2. Synthesis and critically compare engineering and nature's solution to the structural design of composites materials through self-direction and communicate their conclusions clearly to specialist and non-specialist audiences.
  3. Extend their current understanding by communicating the future technical challenges in the design and manufacture of biologically inspired composite materials and structures.

The learning outcomes align to the UK-SPEC A1, A2 and B1 (Engineering Council - https://www.engc.org.uk/standards-guidance/standards/uk-spec/)

Teaching details

The unit comprises a combination of initial lectures to give an overview of nature materials, seminar style discussions, investigative activities and individual presentations by the students on their chosen topics. Students will be expected to research their own subjects in their own time by engaging with provided reading material and participating in feedback tutorials with the Unit Director.

Assessment Details

1. Written assessment on chosen topic: Specialist Written Assignment (60%) (ILO 1-3)

  • This is written as a 12-15 page journal style report
  • This will highlight the students’ ability to synthesis and critically compare nature's structure-function relationships with engineering principles and concepts as a model for the development of new types of high-performance composite materials.

2. 12-minute Specialist Topic Presentation with 3 minutes for questions (40%) (ILO 1-3)

This is assessed by the Unit Director and a second assessor.
