A polymer composite prepared by melt blending, comprising an amorphous polymer; and a crystallizable polymer; wherein upon cooling the polymer composite, the amorphous polymer forms a continuous phase and the crystallizable polymer forms a dispersed phase, and wherein the dispersed phase is less than 200 nanometers in size.

Method of forming holograms in polymer composites with confined crystallization

A polyester block terpolymer comprising an amorphous block comprising a polystyrene dicarboxylate; a crystallizable block comprising a polyethylene glycol; and an aliphatic diol block; wherein the amorphous block is a continuous phase and the crystallizable block is a dispersed phase, and wherein the dispersed phase is less than about 200 nanometers in size.

Block terpolymer with confined crystallization

A composite material having exposed nanofibers is prepared by dividing a polymer nanofiber matrix into sections. A portion of a polymeric substrate material is removed to expose lengths of nanofibers that together can act as a nanoadhesive.

Method for preparing a composite material having nanofibers exposed therefrom

A method facilitates reducing stress in a turbine bucket including a metallic base metal. The method comprises providing a turbine bucket including at least one pocket formed therein, and filling at least one pocket defined in the bucket with a polymer composite having continuous fibers oriented in a resin matrix, such that the fibers have an orientation determined in accordance with a pre-selected frequency tuning of the bucket.

Methods and apparatus for reducing stress in turbine buckets

To address certain deficiencies of carbon fiber material as a filler in a hybrid blade, a glass composite layer is provided as a barrier layer between a carbon fiber resin filler and the metallic main body of the blade. The glass composite layer also advantageously provides a gradient in thermal expansion between the carbon fiber composite and the body of the blade (steel) to reduce interfacial residual stress.
