Curved reinforced support member
First Claim
1. A fiber reinforced body of plastic material in which said body is curved about an axis of revolution and has a generally U-shaped cross section with an inner peripheral edge portion and an outer peripheral edge portion comprising a plurality of relatively long fibers of reinforcing material extending into said body from said edge portions generally in planes containing the axis of revolution of said body and a plurality of relatively short fibers of reinforcing material extending generally circumferentially of said body and in planes perpendicular to the axis of revolution of said body and the majority of said relatively short fibers being in said edge portions.

Abstract
A support member curved about an axis of revolution for mounting on a wheel rim inside a tire chamber to support the tire in a deflated condition. The support member has a generally U-shaped cross section and may have open ends or the ends may be closed with webs having edges joining the radially inner and outer peripheral edges of the support member.
A relatively lightweight high-strength material such as reinforced plastic may be used in the construction of the support member with relatively long fibers of reinforcing material extending generally in planes containing the axis of revolution and relatively short fibers of reinforcing material extending generally circumferentially of the support member and in planes perpendicular to the axis of revolution. Heat-conducting material in the form of wire screen or short lengths of wire may be embedded in the support member to conduct heat away from the surface engaged by a deflated tire.
