Abstract
Low energy fuse for use in transmitting shock waves. The fuse consists of a hollow plastic tube fabricated of an ethylene-chlorotrifluoroethylene terpolymer, with a coating of reactive powder on an inner wall of the tube. The terpolymer contains a third polymer which enhances adhesion of the powder to the tube, and in the disclosed embodiment, the third polymer is hexafluoroisobutylene.
Claims16
A low energy fuse for transmitting shock waves comprising:
- a hollow plastic tube fabricated of a terpolymer consisting essentially of ethylene, chlorotrifluoroethylene, and hexafluoroisobutylene, and
- a coating of pulverulent reactive material on an inner wall of the tube.
A low energy fuse for transmitting shock waves comprising:
- a hollow plastic tube consisting essentially of:
- an ethylene-chlorotrifluoroethylene terpolymer containing substantially equal amounts of ethylene and chlorotrifluoroethylene, and
- an amount of hexafluoroisobutylene,
- the tubing having in inner diameter of about 0.040 inch and an outer diameter of about 0.120 inch, and
- a coating of pulverulent reactive material comprising a homogeneous mixture of about 75 to 90 percent cylcotetramethylenetetranitramine (HMX) and about 10 to 25 percent aluminum on an inner wall of the tube.
A low energy fuse for transmitting shock waves comprising:
- a hollow plastic tube fabricated of a terpolymer containing hexafluoroisobutylene, and
- a coating of pulverulent reactive material on an inner wall of the tube.
A low energy fuse for transmitting shock waves comprising:
- a hollow plastic tube fabricated of an ethylene-chlorotrifluoroethylene terpolymer, and
- a coating of reactive powder on an inner wall of the tube,
