Fiber reinforced thermoplastic composites and methods of making |
| 摘要 |
Methods of making a fiber-reinforced thermoplastic polyurethane composite are described. The methods may include applying a sizing composition to a plurality of fibers to make sized fibers, where the sizing composition may include at least one curative for a thermoplastic polyurethane prepolymer. The sized fibers may be contacted with a thermoplastic polyurethane prepolymer composition to form a resin-fiber amalgam, where the thermoplastic polyurethane prepolymer composition includes 50 wt. % or less of a total amount of the curative that is also present on the sized fibers. The resin-fiber amalgam may then be cured to form the fiber-reinforced thermoplastic polyurethane composite. |

1. A method of making a fiber-reinforced thermoplastic polyurethane composite, the method comprising:
applying a sizing composition to a plurality of fibers to make sized fibers, wherein the sizing composition comprises at least one curative for a thermoplastic polyurethane prepolymer; contacting the sized fibers with the thermoplastic polyurethane prepolymer composition to form a resin-fiber amalgam, wherein the thermoplastic polyurethane prepolymer composition includes 50 wt. % or less of a total amount of the at least one curative that is also present on the sized fibers; and curing the resin-fiber amalgam to form the fiber-reinforced thermoplastic polyurethane composite. |
