A Study on Replacing Bolted Joining with Riveted Joining in Composite Load-carrying Pail of Satellite

摘要

Low weight is of great importance in a composite load-carrying pail of satellite structures. The purpose of this work is to investigate the possibility of reducing weight by replacing bolted joining of the composite structure with riveted joining since the weight of bolted joining structure is usually greater than that of riveted joining structure. The electromagnetic riveting (EMR) technique is used to rivet fiber composite laminates for this purpose. EMR technology and EMR process parameters are investigated in detail and comparison of the corresponding static strength between bolted joint and riveted joint is presented. Results indicated that the static strength of joint conducted by EMR did not decrease obviously, and EMR did not bring installation damage to fiber composite structures. Hence, bolted joining can be replaced with EMR in the composite load-carrying pail of satellite. As a result, the structure weight of load-carrying pail is significantly reduced.
