Abstract: Woven fabric of continuous, untwisted carbon yarn is impregnated with a modified cyanate ester resin or oligomer, preferably at least about 10% by weight of the combined weight of the cured resin and fabric. The cured fabric may be employed as a wet friction material suitable for use in transmission fluid couplings, and the like. The cured composite sheet can be backed with an adhesive film or liquid bonding paste for ease of bonding to one side of the metal portion of the transmission or clutch. Where thicker material is required, two or more cured composite sheets can be bonded together for applications such as transmissions.

Abstract: A bridge plate assembly for use in moving vehicles between rail cars for unloading and loading has a sufficient length to span the space between adjacent rail cars and has sufficient width to accommodate vehicles of varying wheelbase. The plate assembly includes two load bearing plate members, positioned one on top of another, with one end of each plate member being formed and adapted to be attached to the end of a rail car. Each plate member has top and bottom face layers bonded to an intermediate low density core.
