Matériau compositevignette|Multicouche, un exemple de matériau composite. Un matériau composite est un assemblage ou un mélange hétérogène d'au moins deux composants, non miscibles mais ayant une forte capacité d'interpénétration et d'adhésion, dont les propriétés mécaniques se complètent. Le nouveau matériau ainsi constitué possède des propriétés avantageuses que les composants seuls ne possèdent pas. Bien que le terme composite soit moderne, de tels matériaux ont été inventés et abondamment utilisés bien avant l'Antiquité, comme les torchis pour la construction de bâtiments.
Textile performanceTextile performance, also known as fitness for purpose, is a textile's capacity to withstand various conditions, environments, and hazards, qualifying it for particular uses. The performance of textile products influences their appearance, comfort, durability, and protection. Different textile applications (automotive, clothing, sleepwear, workwear, sportswear, upholstery, and PPE) require a different set of performance parameters. As a result, the specifications determine the level of performance of a textile product.
Bending momentIn solid mechanics, a bending moment is the reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend. The most common or simplest structural element subjected to bending moments is the beam. The diagram shows a beam which is simply supported (free to rotate and therefore lacking bending moments) at both ends; the ends can only react to the shear loads. Other beams can have both ends fixed (known as encastre beam); therefore each end support has both bending moments and shear reaction loads.
Textile techniquethumb|Échantillons de géotextiles. Un textile technique est un tricot, tissu, non tissé, corde, tresse, etc., dont le toucher et l’aspect visuel ne sont pas primordiaux, constitués de fibres dites « fibres techniques », ayant des caractéristiques choisies pour une ou des applications bien déterminées (non-feu, résistance mécanique, conductivité électrique, antistatisme, protection, isolation, anticoupure, textiles « intelligents »). En général, ce type de textile doit répondre à un cahier des charges strict imposé par le client, répondant à des normes précises.
Polymère renforcé de fibres de carboneLe polymère renforcé de fibres de carbone, ou PRFC (en anglais Carbon Fiber Reinforced Polymer ou CFRP), est un matériau composite très résistant et léger. Son prix reste à l' assez élevé. De la même manière que le plastique à renfort fibre de verre est appelé plus simplement « fibre de verre », le CFRP prend la dénomination usuelle de « fibre de carbone ». La matrice généralement utilisée dans la fabrication du composite est une résine époxyde ; on peut aussi employer le polyester, le vinylester ou le polyamide.
Plastique renforcé de fibresthumb|Cuves en plastique à renfort fibre de verre. thumb|Tissu fibre de verre/aramide (pour haute traction et compression). Un plastique renforcé de fibres ou polymère renforcé de fibres (en anglais, fibre-reinforced plastic ou FRP) est un matériau composite constitué d’une matrice polymère (appelée résine) renforcée par de fines fibres (souvent synthétiques) à haut module. La résine est généralement un polyester thermodurcissable, un époxyde, un vinylester, ou thermoplastique (polyamide...
User interface designUser interface (UI) design or user interface engineering is the design of user interfaces for machines and software, such as computers, home appliances, mobile devices, and other electronic devices, with the focus on maximizing usability and the user experience. In computer or software design, user interface (UI) design primarily focuses on information architecture. It is the process of building interfaces that clearly communicates to the user what's important. UI design refers to graphical user interfaces and other forms of interface design.
Structural steelStructural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries. Most structural steel shapes, such as -beams, have high second moments of area, which means they are very stiff in respect to their cross-sectional area and thus can support a high load without excessive sagging.
Engineered woodEngineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation to form composite material. The panels vary in size but can range upwards of and in the case of cross-laminated timber (CLT) can be of any thickness from a few inches to or more.
Construction managementConstruction management (CM) is a professional service that uses specialized, project management techniques and software to oversee the planning, design, construction and closeout of a project. The purpose of construction management is to control the quality of a project's scope, time / delivery and cost—sometimes referred to as a project management triangle or "triple constraints." CM is compatible with all project delivery systems, including design-bid-build, design-build, CM At-Risk and Public Private Partnerships.
