When the International Tire Exhibition and Conference opened here today, more than 2,500 people gathered in small meeting rooms to listen to scientists deliver papers on "Metallic Coagents for Bonding Rubber to Metal and Synthetic Fibers" or "Tire Shearography".
For seismic isolation, the total thickness of rubber provides a low horizontal stiffness, whereas the close spacing of the intermediate shim plates provides a high vertical stiffness, relative to the horizontal, for a given bonded rubber area and shear modulus.
After joining DuPont in 1938, he developed the first practical adhesive for bonding rubber to nylon for B-29 bomber tires, discovered light-fast dyes for cotton, led development of dyes for polyester and acrylic fibers, and served as DuPont's Director of Research and Development for synthetic rubbers and plastics from 1963-1980.
Currently, the critical load is estimated using an approach whereby a ratio, that of the overlapping area between the top and bottom bearing endplates to the bonded rubber area, is used to reduce the critical load at zero lateral displacement, referred to herein as the overlapping area method.
Zinc oxide is a necessary ingredient in rubber compounds for bonding rubber to reinforcing steel cord, etc.
"I realised I didn't need a rock climbing shoe—I could just bond climbing rubber right to the artificial foot," he says.
Microstructural analysis using a Scanning Electron Microscope (SEM) was used to investigate bond between rubber and concrete at the Interface Transition Zone (ITZ).
However, certain diamines (e.g., alkyl-aryl paraphenylene diamines) prevent cracking, probably by competing with the C=C bonds in rubber for reaction with ozone.
In the early 1970's, in an effort to cut costs, the Swartzes switched to injection molding, a technique that chemically bonds the rubber sole to the leather without stitching.
Strain energy release rates were also evaluated for growth of a crack along the bond-line, starting at the edges, and compared with those reported previously by Lindley and Teo [Energy for crack growth at the bonds of rubber springs, Plast. Rubber Mat. Appl. 4 (1979) 29 37], Muhr et al. [A fracture mechanics study of natural rubber-to-metal bond failure, J. Adhes. Sci.
