Abstract
A process and product formed therefrom for providing a protective closure for hollow structures that are used in high velocity applications. The protective closure comprises a closure material and a sheath material permanently bond to each other. Both the closure material and the sheath material are "set" in a configuration of the closure. The protective closure is fabricated by having the closure material and the sheath material permanently bonded and "set" to each other by subjecting them to a high energy impulse force.
Claims9
A fabricating process for forming and bonding a laminated protective closure for an open ended hollow structure by permanently bonding together and setting dissimilar materials, comprising the steps of:
- a. Forming a first material undersized to the outside wall of said hollow structure and in the general configuration of the protective closure to be formed;
- b. Forming a second material, comprised of higher physical properties than said first material, to the general configuration of the protective closure to be formed;
- c. Slip-fitting said second formed material to said first formed material;
- d. Permanently bonding said first material to said second material and setting said materials to the configuration of the protective closure to be formed by:
- i. Placing said slip-fitted first and second materials in the proximity of a die of the protective closure to be formed;
- ii. Destroying the memory of both said slip-fitted materials by subjecting said slip-fitted materials to a high energy impulse force to force said first material against said second material and force both slip-fitted materials to assume the configurations of the die.
