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...
