Novel Powder Epoxy Composites for Thick-Section Structures
25 Jan 2021 | Contributor(s):: Conchur O'Bradaigh
This seminar discusses the ongoing work at The University of Edinburgh on the processing, design and testing of thicksection composites for industrial structures such as large wind and tidal turbine blades, via powder epoxy resin systems. Thick-section composite parts are difficult to manufacture...

Structural Self-sensing Based on Measuring the Resistance, Capacitance or Inductance of the Structural <aterial, Without Sensor Incorporation
06 Nov 2023 | | Contributor(s):: Deborah Chung
Structural self-sensing refers to a structural material sensing itself without sensor incorporation. Compared to sensor incorporation, advantages include low cost, high durability, large sensing volume and the mechanical properties being not degraded. The self-sensing ability makes the structural...

The Challenges of Determining the Strength of Composites
24 Nov 2020 | | Contributor(s):: Michael R Wisnom
Why are there such large differences in reported strengths of composites? Some of the reasons are the definition of strength, material variability, poor test methods, and subtle variations in carrying out the tests. But there are other important factors that affect strength that are not...
