Patent number: 9421703Abstract: Polymer-based materials and processes suitable for producing panels, for example, panels for use in a fan shroud abradable seal of a turbofan engine. Such a process includes introducing constituents of an expandable foam material into a continuous forming apparatus that continuously compounds the constituents into a partially-cured compounded polymeric material, which is then continuously formed with the continuous forming apparatus to produce a continuous form having a constant cross-sectional shape transverse to a continuous forming direction of the continuous forming apparatus. A portion of the continuous form is then deformed to produce a preform, and the preform is cured within a restricted volume to cause the preform to expand and produce the panel.Type: GrantFiled: December 22, 2011Date of Patent: August 23, 2016Assignee: General Electric CompanyInventors: Michael Dominic Schulte, Eric Joseph Aho, Peter Kennedy Davis, Wendy Wen-Ling Lin, Michael Joseph O'Brien, Brian Dominic Stephens

Patent number: 8921462Abstract: A rubber composition with disperse phase particles containing poly(phenylene ether) can be formed by a method that includes melt blending an uncured rubber with a poly(phenylene ether) composition containing a poly(phenylene ether) and an oil to form an uncured rubber composition, then curing the uncured rubber composition. Before being blended with the rubber, the poly(phenylene ether) composition exhibits a glass transition temperature of about 40 to about 140° C., and during blending with the rubber, the oil component of poly(phenylene ether) composition migrates from the poly(phenylene ether) composition to the rubber, leaving a poly(phenylene ether)-containing disperse phase that gives rise to a second hysteresis peak temperature of about 160 to about 220° C. as measured by dynamic mechanical analysis of the cured rubber composition.Type: GrantFiled: December 16, 2013Date of Patent: December 30, 2014Assignee: SABIC Global Technologies B.V.Inventors: Scott Michael Fisher, Qiwei Lu, William Eugene Pecak, Michael Joseph O'Brien
