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...
