Book Synopsis Electron Beam Curing of Composites by : Felipe Wolff-Fabris
Download or read book Electron Beam Curing of Composites written by Felipe Wolff-Fabris and published by . This book was released on 2011 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Electron beam curing technology for advanced composites has emerged as a credible and attractive alternative to thermal curing for most composite products. Technical advantages, such as aerospace structures, include curing at room temperature, using low-cost tooling, and the ability to fabricate large integrated structure including structures too large to fit inside autoclaves. Studies by aerospace companies have shown potential cost savings of 10-60% by using electron beam curing. In this book, both theoretical and practical aspects of electron beam curing of composites are presented, intending to build a bridge between the academic knowledge and the industrial applications."--Publisher.
Book Synopsis Electron-Beam (E-Beam) Processing as a Means of Achieving High Performance Composite Structures by :
Download or read book Electron-Beam (E-Beam) Processing as a Means of Achieving High Performance Composite Structures written by and published by . This book was released on 2001 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron-beam (E-beam) curing is among the key out-of-autoclave technologies being explored for future advanced composite and adhesive applications. E-beam irradiation curing is capable of rapid and through-thickness curing of composite samples up to 2-in thickness, eliminating the need for long cure cycles in the autoclave. However, current resin and adhesive chemistries are optimized for cure by thermal initiation, which involves slow ramps and long cure cycles, particularly for thermoset composites based on epoxides. Therefore, in order to provide improved performance in composite systems cured by E-beam irradiation, a program was undertaken to investigate performance and formulation effects in two E-beam curable systems. One system, a free-radical-cured acrylic system, introduces the concept of interpenetrating network structures as a means of meeting performance requirements in E-beam-processed composites. The second resin system incorporates cationic curing of epoxides induced through Lewis acid or cation generating initiators. Additionally, a new approach to toughened interpenetrating polymer networks (IPNs) based on simultaneous cure using both free-radical and cationic-cure mechanisms is proposed along with initial experimental characterizations. The results of formulation and processing modifications on key properties of adhesives, resins, and composites structures are demonstrated.

This book was released on 2012-02-07 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text examines the effect of radiation on polymers and the versatility of its industrial applications. By helping readers understand and solve problems associated with radiation processing of polymers, it serves as an important reference and fills a gap in the literature. Radiation processing can significantly improve important properties of polymers, however, there are still misconceptions about processing polymers by using ionizing radiation. This book explains the radiation processing of polymeric materials used in many industrial products including cars, airplanes, computers, and TVs. It even addresses emerging "green" issues like biomaterials and hydrogels.
