10h00-10h45: Design (Prof. C. Dransfeld, TU Delft, Netherlands)
Course Content

Successful design with composites results from the holistic approach to shape, fabrication and material. With composites being intrinsically heterogeneous and composed of stiff reinforcement elements, arranged and connected by a soft polymer phase, the manufacturing of an object and creation of the composite materials coincide. This pauses challenges and created opportunities when exploited in a smart way. The “gestalt” of a composite product, its entirety being more than the contributing elements, results from a supreme control of the composite material at several scales, from the fibre interface, to textile architecture up to large scale joining processes. Finally the convergence of computational design, digital fabrication and engineered functional materials augments the design process with composites to unprecedented levels.

11h50-12h35 Durability (Dr. P. Davies, IFREMER, France)
Course Content


While we can today predict the short term properties of fibre reinforced composites with some confidence this is not always the case for long term behaviour. Prediction of the effects of fatigue, creep, environmental factors and in particular the coupling between these effects still poses significant problems. This presentation will give an overview of recent work in this area, using the current development of composite structures for marine renewable energy to illustrate what we know and where further work is needed.


Dr. P. Davies is a researcher at the French Ocean Research Institute (IFREMER): He has been working on the aging and long term behaviour of polymers and composites in a marine environment for over 25 years:


12h35-13h30: Lunch break
13h30-14h15: Biocomposites (Prof. Em. I. Verpoest, KU Leuven, Belgium)
Course Content

First, a large number of examples will be presented where natural fibre composites have been and/or are being used, and explain the main reasons for it. This would be the “inspiring” part, opening the view of young researchers on where and how natural fibre composites are being used. Second, the basics on the morphology and properties of natural fibres will be highlighted, and finally some aspects of natural fibre composites which need somewhat more attention will be discussed, like the way we measure fibre properties, the recent developments in fibre preforms, the discussions on LCA-studies for NFC’s… This would be the more “scientific” part.

14h20-15h05: Tools and models for a predictive simulation of composite forming processes (Dr. N. Hamila, Insa Lyon, France)
Course Content

The ambition to shorten the processing cycle continuous composite materials on developable geometries requires to better control the defects of the parts and to provide engineers with information about their mechanical and material properties in service. The use of the numerical tools seems to be a beneficial way to achieve these objectives, while avoiding a prohibitive cost of development by trial error approach. Most frequently encountered forming defects are wrinkling, fiber crack, fiber slippage or matrix deconsolidation. Whatever the defect evoked, its influence on the mechanical properties makes the part often unusable. The modeling of composite materials is diversified both by the nature of the matrix and its temperature dependence, and by the wide variety of types of continuous fiber reinforcements. For each of these cases, mechanical models and numerical formulations are proposed.


Dr. N. Hamila : Graduated from Paris-Sorbonne University (UPMC) in mechanical engineering in 2004, N. Hamila defended his PhD on December 7, 2007 at INSA Lyon. He has since been Associate Professor at INSA Lyon, where he continues his research on modeling and simulation of composites during the manufacturing process.


15h05-15h15: Short break
15h15-16h00: Liquid Composite Molding (LCM) Processes (Prof. S. Advani, University of Delaware, USA)
Course Content

Various composite manufacturing processes that fall under the umbrella of LCM will be introduced. Their similarities, differences, pros and cons will be identified. The processing challenges at the macro and micro level will be presented. The approach to modeling and simulating these processes will be highlighted. Material characterization methods to determine the fabric permeability will be put forth. The role of such simulations in the design, optimization and control of the LCM process to manufacture void free complex parts will be demonstrated with examples.


Prof. S.G. Advani :



16h05-16h50: Discontinuous fiber composites (Prof. C.L. Tucker, University of Illinois at Urbana-Champaign, USA)
Course Content

Composites with discontinuous fibers are often processed by injection or compression molding.  Flow during the molding process will change the orientation of the fibers, which affects the mechanical properties of the finished part.  This talk will discuss how fiber orientation can be described mathematically, measured experimentally, and predicted in computer simulations of molding.  We will also show how the orientation information is used to calculate stiffness and thermal expansion of the final material.


Charles L. Tucker is professor emeritus of Mechanical Science and Engineering at the University of Illinois at Urbana-Champaign, USA.  He developed some of the first computer simulations of compression molding, and with Suresh Advani he pioneered the tensor approach to modeling fiber orientation in discontinuous fiber composites.  He was the first to apply this approach to predict fiber orientation in injection-molded composites, and his methods are used in all commercial injection molding software programs.

18h00-18h45 : Double-double - a new way to reduce weight (Pr. S. Tsai, Stanford University, USA)
Course Content


We have discovered that saving 50 percent of weight over a quasi-isotropic CFRP composite structures can be routinely achieved if double-double laminates are used in place of the traditional 0, ±45, 90. This means that CFRP would weigh 30 percent of aluminum. The approach is to combine conventional FEA with Lam search optimizer.  This Excel-based search engine can instantly select the best laminate and controlling load under multiple loads.  With the controlling load that sets the heaviest thickness, all remaining areas can be thinned so the strength is equalized for the entire structure.  Cost of fabrication can be reduced not only because of less material is needed but with 1-axis layup when the deposition rate can be 6 times faster than the quad layup, and with better quality and easier inspection.  Essential for our approach include trace, strength ratio, homogenization, double-double, and Lam search.  They can be found in our Paris Airshow book of June 2019, which is posted online for free download.  Lam search is also available free.
