Determination of Reliability of Epoxy Potting Compound and Eutectic Metal for Terminating the Armor Wire of Variable Depth Sonar Towline Systems
Abstract
Mechanical methods currently in use for terminating the armor wire of Variable Depth Sonar (VDS) towcables have proven unreliable. NASL undertook the development of a poured socket as a means of effecting a more suitable termination. As part of this work, NASL developed a rigid epoxy compound, designated NASL-E-4, consisting of an epoxy resin, a curing agent and a filler material in sufficient amounts to inhibit cracking due to the severe operating requirements of VDS systems. NASL-E-4 epoxy compound and a low temperature melting eutectic metal (Cerro-Tru) were evaluated as socketing materials. Results of the work, conducted using SQA-10 VDS towcables, showed that a poured socket using the NASL-E-4 epoxy compound developed the full strength of the cable whereas the eutectic metal developed no greater than about 75% of the strength of the cable.
