For engineers and designers

Composites is a key enabling technology with uses in an ever-increasing number of industries. As composite materials behave differently to traditional materials such as steel and aluminum, an understanding of these differences and appropriate design methods are required to achieve structural integrity.

This growing library of articles (below) are written to assist engineers and designers introducing composites to projects.

About the author

Dr Rikard B. Heslehurst, PhD, MEng, BEng(Aero), FIEAust, FRAeS, CPEng, FSAMPE), is the owner and director of Heslehurst and Associates Pty Ltd, providing composite engineering consultancy services in design and development.  He also runs several training courses in composite materials and structures.

Rik is currently the Senior Engineer for Abaris Training – Reno Nevada, USA.  He consults for the Australian Defence Force, Civil Aviation Safety Authority, Raytheon Missile Systems, NASA, USAF, Boeing Airplane Company, Bombardier Aerospace, Australian Space Safety Office, John Deere, Walt Disney Imagineering, SRAM-Zipp Wheels and SP Systems-UK. He recently retired as a Senior Lecturer in the School of Engineering and Information Technology of the University College, UNSW at the Australian Defence Force Academy (UNSW@ADFA).

Rik is a regular contributor to Composites Australia’s magazine Connection, as author of the popular “Composite Engineer’s Viewpoint” series. Articles published to date are available below in PDF format.
