The Challenges of Determining the Strength of Composites
24 Nov 2020 | Contributor(s): Johnathan Goodsell
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...

US-COMP: Next Generation of Composites Materials for Crewed Deep Space Missions
15 Dec 2023 | Contributor(s): Johnathan Goodsell
Current state-of-the-art composite materials are not light/strong enough for crewed missions to Mars and beyond. Structural components of deep space vehicles require lighter/stronger materials for fuel efficiency. The NASA Space Technologies Research Institute (STRI) for Ultra-Strong Composites...

Woven fabrics UMAT- a coupled material model
02 Aug 2017 | Contributor(s): Ali Roumani
One of the advantages of woven fabrics over unidirectional prepregs is their superior formability thanks to the large shear deformation capability. There exists, however, a limit on the shear deformation of woven fabrics, namely the wrinkling. Applying tension to delay wrinkling during forming...
