  1. 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...

  2. Control of Reaction Fronts for Rapid Energy-Efficient Manufacturing of Multifunctional Polymers and Composites

    04 Jun 2021

    This lecture describes a new manufacturing platform technology that allows for near net-zero energy fabrication of structural polymers and composites. The approach is predicated on the exploitation of a self-propagating polymerization reaction occurring in a system undergoing reaction and...

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

    16 Oct 2020 | Contributor(s):: Kenneth L Reifsnider

    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....

  4. 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...

  5. 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...

  6. Practical Developments in Multiscale Modeling of Composites

    07 Apr 2021 | Contributor(s):: Steven Arnold

    Validated models (be they data driven or physics based) can accelerate the design, certification, and ultimate deployment of novel materials and structures by allowing rapid iteration and virtual experimentation while at the same time minimizing the need for expensive and time consuming physical...

  7. Recent Developments in Computational Approaches to Model Laminated Composite Shells and Damage and Fracture in Solids

    16 Feb 2021

    In this lecture, two different topics of considerable interest to composite materials and structural mechanics communities are discussed. The first topic deals with the development of locking-free shell finite elements with thickness stretch for the nonlinear analysis of isotropic and laminated...

  8. Rheology of Carbon Fiber Thermoplastic Polymer Composites

    26 Apr 2021 | Contributor(s):: Byron Pipes

    The rheology of fiber–reinforced thermoplastic composites will be presented with specific focus on several topics studied over the past three decades. Interest in the elongational viscosity of collimated, discontinuous fiber systems was initiated by the introduction of impregnated, stretch...

  9. Sustainable Manufacturing of Composite Materials

    21 May 2021 | Contributor(s):: Pascal Hubert

    The growing use of composite materials in aerospace, transportation, recreational products and renewable energy production manufacturing has created a critical need for low-cost sustainable manufacturing methods. The current methods of consolidation and cure are not compatible with the projected...

  10. 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...
