The general objective of this course is to present Polymer and Metal Matrix Composites (MMC) as structural materials, from the point of view of their synthesis, their implementation and/or shape and their reactivity. · Polymers Composites · To provide the skills necessary for the development, characterization and implementation of polymer matrix composites (thermoplastics and thermosets) · Industrial composites, Synthesis of polymer networks (permanent or reversible networks). · Notions of interface and fiber/polymer interphase · Structural transformations (sol-gel transition, vitrification, phase diagrams). Chemo-rheology and characterization of networks (swelling, rubber elasticity...), model networks. Influence of fillers. · Mass transfers and heat exchanges in processing. Flow in processing machines. -Permeabilities in porous reinforcements. Study and in-situ control of the implementation processes (RTM, RIM, SMC, etc...) · Metal Matrix Composites (MMC) · Overview of the main MMC currently used in industry and their main industrial applications (Course 1). · Concise presentation of the different ways of MMC synthesis at an industrial (Course 2). · Focus on Reactivity drawbacks observed during the implementation or the use of the MMC (properties evolution, aging, damaging) and their understanding based on Phase diagrams (Course 3) · Presentation of cutting-edge and new ways of synthesis (MMC in-situ synthesis), current research on mechanical properties evolution (bimodal MMC) and the interest for “new” reinforcements (Carbides type and other) (Course 4). · Keywords: Fibrous reinforcements, Particle reinforcements, Polymer matrix, Metal matrix, - Implementation Thermodynamics, Reactivity, In-situ synthesis
