elevated temperatures ( °C to °C), validate key mechanical properties of these composites, and demonstrate cost-saving fabrication methods at the subcomponent level. Electron beam curing of polymer matrix composites is an enabling capability for production of aerospace structures in a non-autoclave process. Electron-beam (e-beam) curing is an emerging manufacturing technology that offers high potential as a low-cost, nonautoclave process for cure of large composite structure. The advantages of electromagnetic processing to cure polymer-matrix composites include the following (Goodman et al., ): Reduced curing .

The first experiments with electron beams date from as early as in the US, but the first attempts to cure varnishes with Electron Beam Curing (EBC) were only made in The essence of EBC is that an electron bundle induces cross-linking in a coating that has been applied, which actually involves radical polymerization as we know it from. Electron beam curing of composites – historical background The initial experiments that demonstrated the efficacy of EB curing for composite materials were conducted in the late ’s by Dr Walter Brenner, a professor of chemistry at New York University and then a consultant to the accelerator manufacturer, Radiation Dynamics.

manufacture of carbon fiber composites. Penetrating X-rays generated with high-energy, high-power electron beam (EB) accelerators can cure structural composites while they are constrained within inexpensive molds; thus reducing cure times, eliminating heat transfer concerns and potentially hazardous volatile emissions during the curing process. Electron beam (EB) radiation processing is being used for cross-linking of such composite matrices [3, 4]. Main advantages of this process are: low temperatures, fast reaction time, low emission of volatile materials and a product with improved mechanical properties. The action of.

Electron beam curing technology for advanced composites has emerged as a credible and attractive alternative to thermal curing for most composite products. Technical advantages, e.g., for aerospace structures, include curing at room temperature, using low-cost tooling, and the ability to fabricate large integrated structures.

Fiber-reinforced polymer composites are also cured using high-energy electron beams or X-rays. These beam plants offer significant advantages for the production of small or medium series of a. Studies by aerospace companies have shown potential cost savings of 10–60% by using electron beam curing.

Electronic Beam curing (EBC) is a surface curing process in the manufacture of high pressure laminate (HPL) boards.

The process applies color to a single sheet of Kraft paper which is adhered to a HPL board in such a way that it will keep its color durably while remaining scratch-resistant.

Unlike other HPL creation methods, EBC does not use heat. The EBC machine used in the curing process. Abstract. SinceAEROSPATIALE has developped a new curing process of composite using electron beam and X-rays with the first objective to manufacture filament wound motor by: Curing of composites manufactured by vacuum bagging is already used in electron beam curing.

An example is shown in Fig.where an aircraft part for military applications is passing under the electron beam and is being cured []. The accelerated electrons traverse the bag film to reach the composite and to cure the resin.

Electron-beam curing produces a finish similar to that of traditional solvent-evaporation processes, but achieves that finish through a polymerization process. Electron microscopes An electron microscope uses a controlled beam of electrons to.

Electron Beam Curing of Epoxy Composites. Felipe Wolff‐Fabris. University of Bayreuth, Department of Polymer Engineering, Faculty of Applied Natural Science, Universitaetsstra Bayreuth, Germany. Book Editor(s): Prof. Jean‐Pierre Pascault. Cited by: 1. Electron beam (EB) curing is a technology that promises, in certain applications, to deliver lower cost and higher performance polymer matrix composite (PMC) structures compared to conventional thermal curing processes.

PMCs enhance performance by making products lighter, stronger, more durable, and less energy demanding. Researchers at ACSION Industries and Oak Ridge Center for Composite Manufacturing Technology have recently achieved a major breakthrough for the composites industry by successfully developing Electron-Beam (EB) curable epoxies and EB curing cycles that reduce processing time and cost while meeting the demanding requirements of high-performance composite by: @article{osti_, title = {Electron beam curing of epoxy resins by cationic polymerization}, author = {Janke, C J and Dorsey, G F and Havens, S J and Lopata, V J}, abstractNote = {Preliminary investigations have determined that conventional epoxy resins can be cured at selectable temperatures with high glass transition temperatures (essentially the same as with thermal curing), while still.

In this work, Electron beam, delivered through a thin foil, into a purified gas filled chamber, was used only as an excitation tool to generate UV light. Curing of coatings induced by Plasma is suggested by Misev et al. In this case, a 3-dimensional object is placed in a Plasma discharge chamber and initial curing takes place upon exposure.

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.

Society of Plastics Engineers. Composites are growing in importance and are moving from high-tech applications to consumer goods. Therefore the importance of price and production time increases. For curing thick composites, electron beam (EB) is an alternative to today’s standard, thermal curing.

In order to master EB-curing it is important to have a good understanding of not. SourceBook is a comprehensive directory of composites industry suppliers, manufacturers and service companies for the entire composites industry.

Search more than 2, industry suppliers and read important updates in the industry overview, along with the links to Industry Organizations and a. Thermal curing may provide the answer for some thicker materials, however e-beam curing has several advantages over the thermal curing process: Lower energy consumption (as little as 10% of thermal cure), especially for large products.

Curing Technology High-performance resins like epoxy and bismaleimide (BMI) are typically cured in an autoclave under high heat in a vacuum. A new class of resins is emerging, called out-of-autoclave (OOA) resins, that are cured under heat only and thus bypass the need for vacuum.REVIEW OF ELECTRON BEAM AND X-RAY ADHESIVE CURING A detailed review of EB/X-ray curing of adhesives was performed by the authors [11] to assess the state of the art of the technology.
