  1. Emerging Role of Process Models & Simulations in Composites Manufacturing

    07 Dec 2020 | Contributor(s):: Suresh Advani

    This talk will highlight the ever increasing benefits of process modeling in Composite Manufacturing processes. First, the use of science base approach of materials processing, which integrates material parameters with transport phenomena at various scales during manufacturing to create...

  2. 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...

  3. 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...

  4. Defect Coupling Predicting the Strength and Life of Fiberous Composite Laminates

    16 Oct 2020

    After more than 30 years of careful experimental investigation and exhaustive development of discrete damage analysis methods including integrated computational mechanics methods, our community knows a great deal about how discrete defects such as matrix cracks and defect growth (e.g....

  6. A Manufacturing Sensitive Design Strategy for Composite Materials Using Physical Modeling and Stochastic Simulation of Defects

    02 Oct 2020 | Contributor(s):: Ramesh Talreja

    This presentation outlines a strategy for designing composite structures accounting for the presence of defects that are inevitable in a practical manufacturing process. The essential ingredients of the strategy are incorporation of defects in physical models for assessment of composite...

  7. Digital Disruption of Composites Manufacturing and Design

    18 Sep 2020 | Online Presentations | Contributor(s):: Anoush Poursartip

    Composite materials and structures are an excellent example of how engineering practice often outpaces scientific knowledge. Born in the analog world of the 1960s, carbon-fibre composites manufacturing and design practice is a complex and often fragile construct that is primarily driven by the...
