Designing of textile preforms for ceramic matrix composites
Advanced Composite Materials, 1999Two and three dimensional fiber preforms produced by textile forming techniques have been used successfully for reinforcing ceramic-based composites. The focus of this paper is on the design of textile preforms for reinforcing ceramic matrix composites. The research work consisted of the following tasks: (1) identification of typical loading conditions

Approximate solutions for preform design in rolling
International Journal of Machine Tool Design and Research, 1984Abstract In ingot rolling the defects of overhang at the front and rear ends plates. The defect shapes that occur under the plane-strain condition can be eliminated with proper design of end shapes in ingots. This paper presents an approximate solution for design of ingot end shapes.

Preform design for closed die forgings: Experimental basis for computer aided design
International Journal of Machine Tool Design and Research, 1975Abstract A rationalized procedure, incorporated into a computer programme, for the design of preforms for certain forging cross sections is outlined. The performance of preforms designed using this procedure is compared with those of other preforms, from the point of view of die filling, expected wear of the final impression and material utilization,

Approximate solutions for preform design in shell nosing
International Journal of Machine Tool Design and Research, 1983Abstract Two approximate solutions for preform design in shell nosing are derived. The degree of approximation was examined by the accurate numerical solution based on the new approach by the finite element method, for an example of uniform wall thickness of the nosed shell.

Computer Aided Preform Design for Long Hot Forgings
1977Long forgings are made from bar stock and normally require several preforming stages, the number employed being governed by the process technology and economic considerations of the quantities required. If the cross sectional area of the component varies appreciably along its length, material must be distributed along the length of the stock by drawing

Principles of Preform Design for Stretch Blow Molding Process
Polymer-Plastics Technology and Engineering, 1983Abstract The manufacture of plastic containers for carbonated beverages from polymeric resins by stretch blow molding technology has rapidly grown in recent years. Due to the unique properties of PET, such as high strength, transparency, surface gloss, low permeability, light weight, and recyclibility, billions of carbonated beverage bottles from ...
