High-performance metal matrix composites of copper, aluminum, and/or titanium are produced by embedding nanocarbon reinforcement into metal foil or sheet which is concurrently laminated into a multilayer structure to produce high-performance materials for thermal management, enhanced electrical conductivity, armor products and high-strength composite structures.

A tubular implement, such as a container, in particular a container (pipe for transport) for food or beverages such as a drinking straw, includes a first part having a sheet of wood veneer rolled to form the tubular implement in the form of a cylinder.

A multi-layer co-extruded film includes a first layer having a first color and a second layer having a second different color, wherein the first and second layers are co-extruded layers. The multi-layer co-extruded film also includes a plurality of intermittently stretched regions, wherein the multi-layer co-extruded film exhibits a perceivable color change when subjected to a strain. In perceivable color change or E between about 2.50 and about 7.00. Methods of forming a multi-layer co-extruded film includes coextruding a first layer having a first color with a second layer having a second different color and intermittently stretching a plurality of regions of the multi-layer co-extruded film, wherein the first layer and the second layer are co-extruded and intermittently stretched to exhibit a perceivable color change when subjected to a strain.
