The Challenges of Determining the Strength of Composites
out of 5 stars
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...
Automating the Lay-up of Geometrically Complex Composite Structures Made from Preimpregnated Reinforcements: a Route to a Roadmap
04 Nov 2020 | Contributor(s):: Kevin Potter
A significant amount of research and industrial effort has been expended on the development of equipment such as automated fibre placement machines to lay-up prepregged reinforcements into structures of relatively simple geometry such as wing skins and spars, and fuselage structures. These...
