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...
Hierarchical Multi-Response Gaussian Processes for Uncertainty Analysis with Multi-Scale Composite Manufacturing Simulation
23 Feb 2022 | Contributor(s):: kai kai zhou zhou, Ryan Scott Enos, Dianyun Zhang
Variations of constituent fiber and matrix properties and process conditions can cause significant variability in composite parts and affect their performance. The focus of this paper is to establish a new computational framework that can efficiently quantify the uncertainty propagation of...
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...
