How would you link automobiles, interior design, aerospace and shower cubicles? With a booming innovative momentum based on composite technology. Because the language of materials is not hermetic, mechanical, cold, hard. On the contrary, it is a living language that is creative and nourished by the observation of physical laws. This book invites us to penetrate into the intimate life of materials as well as that of composite materials and to learn to draw elements from an explained science in order to explain phenomena and elaborate new models... Flow dynamics, deformation of solids, capillarity... This work teaches the readers a grammar thanks to which they can acquire a new vision of physical phenomena and manufacturing processes. Based on interviews with five composite specialists, Francisco Chinesta signs a great book that celebrates a domain appealing to a creativity that can be found in students, industrial partners or technicians as much as in university researchers.
