The concept that fabrics could be designed to meet particular functionality specifications is comparatively new. With high-performance composites, in spite of the fact that, the whole strategy of designing and fabricating a component might be labored out earlier than production. the aim of this booklet is to offer an built-in method of the layout and production of goods from complicated composites. It exhibits how the fundamental habit of composites and their constitutive relationships can be utilized throughout the layout level, which minimizes the complexity of producing composite elements and decreases the repetitive "design-build-test" cycle. Designing it correct the 1st time goes to figure out the competitiveness of a firm, the reliability of the half, the robustness of fabrication approaches, and eventually, the associated fee and improvement time of composite components. so much of all, it's going to extend using complex composite elements in fields that use composites basically to a restricted volume at the present. to accomplish those pursuits, this e-book offers the layout and fabrication of novel composite components made for computing device instruments and different purposes like robots and automobiles.This e-book is appropriate as a textbook for graduate classes within the layout and fabrication of composites. it is going to even be of curiosity to practising engineers studying approximately composites and axiomatic design.A CD-ROM is integrated in each replica of the e-book, containing Axiomatic CLPT software program. This software, constructed via the authors, will support readers in calculating fabric homes from the microstructure of the composite.This e-book is a part of the Oxford sequence on complex production.

Example text

In one method, fibers and matrix are processed directly into the finished structure. INTRODUCTION TO COMPOSITE MATERIALS 37 Examples of such processes are filament winding and pultrusion. In the second method, the matrix is impregnated into the fiber to prepare ready-to-mold sheets that can be stored and later processed to form laminated structures by autoclave molding or compression molding. Ready-to-mold fiber-reinforced polymer sheets are available in two basic forms, prepregs and sheet molding compounds.

Polyimides They are more expensive and less widely used than polyesters or epoxies but can withstand relatively high service temperatures. The polyimide chain, which is rigid INTRODUCTION TO COMPOSITE MATERIALS 33 and heat resistant owing to the presence of aromatic ring structures, results in a high stiffness, a low coefficient of thermal expansion, and a service temperature as high as 400 C for several hours. However, like other thermosets, they are brittle. Polyimide resin systems are used for electrical and low-friction products in the aerospace industry, as well as in office equipment.

3 Composite Properties Composite properties vary over a wide range according to the choice of fiber and matrix and the direction of loading. The designation of the different composites consists of the name of the fiber followed by the name of the matrix.
