SYSTEMATIC FAILURE TESTING OF CARBON COMPOSITE REINFORCED PULSE MAGNETS

Results will be presented of the testing to stress failure of a series of small, 10 mm bore pulse magnets reinforced with different varietie s and thicknesses of carbon composite. The field reached at failure al lows a calculation of the stresses generated within the carbon fiber a nd a consequent comparison with computer models of highly stressed com posite reinforced magnets. Where necessary, empirical corrections can be made in light of the experimental results. It will be shown that an accurate estimation of the radial and axial elastic modulus of the co mposite is of paramount importance in the modeling of stress transfer throughout the shell. The future utility of composites will be discuss ed together with an examination of the alternatives. (C) 1998 Elsevier Science B.V. All rights reserved.
