Abstract
A novel Aromatic Thermosetting Copolyester (ATSP) fully dense sheets can be processed by recycling the foam structure with unique combination of properties including mechanical strength and high temperature performance (compared to PEEK) to help improve part functionality, gain long-term reliability and cost savings. ATSP machinable plates can be used in valves, fittings, bearing, bushing, seals, aerospace parts and pump components.
Claims18
A method of synthesizing a foam comprising:
- preparing a solid state dry powder comprising an aromatic thermosetting copolyester, and wherein the aromatic thermosetting copolyester is selected from the group consisting of:
- an aromatic thermosetting copolyester comprising a first oligomer having a carboxylic acid end group and a second oligomer having an acetoxy end group;
- mixing the solid state dry oligomeric powder with a carbon nanofiller;
- thermal cycling the mixture of the solid state dry powder with the carbon nanofiller, and wherein the thermal cycling is configured to cause melting, and wherein the thermal cycling includes a two dwell stage thermal cycle defined to include a first dwell stage set at about 202° C. for about 90 minutes and a second dwell stage set at about 270° C. for about 150 minutes;
- and
- curing the mixture to cause a reaction between the carbon nanofiller and the aromatic thermosetting copolyester to structurally link chemically the carbon nanofiller and first and second oligomer chains to form a chemically contiguous structure foam material.
