Abstract
A pipe coupling comprises a body of fiber glass reinforced plastic which has a rubber sleeve embedded therein. The sleeve is a one piece unit which includes specially shaped sealing gaskets on either end and has a rubber liner spanning the area between these sealing gaskets. The sleeve is stretched onto a steel and plastic molding mandrel, which places the rubber liner under tension, reduces the cross- sectional area of the liner and compensates for thermal expansion of the liner during curing. The mandrel/sleeve combination is rotated in order to wind a thermosetting resin impregnated fiber glass roving around the outer circumference of the mandrel/sleeve combination, thus embedding the sleeve in the fiber glass reinforced resin matrix. The thermosetting resin is cured at elevated temperatures, hardening into a rigid coupling with the embedded rubber sleeve integral therewith. Thereafter the hardened coupling is stripped from the steel and plastic mandrel and subjected to a further curing and finishing operation. The curing of a polyester body with a peroxide while in contact with a rubber surface is also claimed.
