Method of making synthetic composite fuel metering membrane

摘要

A method of making a synthetic composite flexible diaphragm by applying an elastic polymer to only one side of a sheet of fabric of warp knitted polyester fibers, disposing the coated fabric in a mold, and while in the mold applying heat and pressure to the coated fabric to force the elastomeric polymer into the interstices of the fabric, mold the diaphragm to a predetermined configuration, and cure the elastomer to produce a molded diaphragm which is at least substantially impervious to liquid fuel.
