Multiscale Modeling of Damage Mechanics of Fiber Reinforced Polymer Composites From Micro- to Macroscale: The (Virtual) Reality and Challenges Ahead
13 May 2022 | Contributor(s):: Wim VAN PAEPEGEM
Multi-scale modelling of composites is a very active topic in composites science. This is illustrated by the numerous sessions in the recent European and International Conferences on Composite Materials, but also by the fast developments in multi-scale modelling software tools, developed by large...
The Story of Permeability in Liquid Composite Molding (LCM): How to Devise and Validate Process Simulation Software?
13 Apr 2022 | Contributor(s):: Francois Trochu
Permeability characterizes the capability of establishing a fluid flow through a porous medium. This lecture aims to present a summary on the state-of-the-art knowledge on permeability in LCM together with a discussion on open questions. The Story of Permeability in Liquid Composite Molding (LCM)...
Capillary Effects in Fiber Reinforced Polymer Composite Processing: A Zoom on the Flow Front
06 Apr 2022 | Contributor(s):: Véronique Michaud
Capillarity plays a major role in many natural and engineered systems, from nutrient delivery in plants, management of humidity in soils, to heat pipes and porous systems for spill recovery. In composite manufacturing, particularly in Liquid Composite Molding processes, capillary effects take...
Composite Materials: Where We are and Where to Go (Mechanical and Electrical Properties of Polymer Composites)
02 Mar 2022
Composite materials have developed in the last 60 years from a just new material into a class of established engineering material with surprisingly outstanding properties. Best demonstrated as being the material of choice in the aerospace industry. The idea of fibre reinforced composites was to...
Fiber-Optic-Based In-Process Monitoring of CFRP Structures for Material Quality Assurance
27 Jan 2022 | Contributor(s):: Nobuo Takeda
Although carbon fiber reinforced polymer (CFRP) composites have been used extensively in many aerospace structures such as Boeing 787 and Airbus 350, low-cost and high-rate production CFRP are highly demanded for next-generation single-aisle commercial aircraft. Competition has been increasing...
Fibrous Shell Approach and 3D Second Gradient Modeling for Textile Composite Draping
10 Dec 2021 | Contributor(s):: Philippe Boisse
Composite manufacturing processes are often complex and process simulation is a way to avoid costly trial-anderror development. Simulations of composites textile reinforcements draping use shell finite elements for which the bending behavior is very particular. The fibrous composition of the...
A Semi-Discrete Model for Progressive Damage and Failure of Fiber Reinforced Laminates
15 Nov 2021 | Contributor(s):: Anthony M Waas
High-strength and high-stiffness carbon fiber-reinforced polymer composite laminates (CFRP) are being increasingly used for primary load bearing structures in many industries. The most common material system used is based on thermoset resins (matrix material), which come in the form of convenient...
