Composite material reinforcement materials. Another important factor is the gross quantity of material to be produced. Large quantities can be used to justify high capital expenditures for rapid and automated manufacturing technology. Small production quantities are accommodated with lower capital expenditures but higher labour and tooling costs at a correspondingly slower rate. Many commercially produced composites use a polymer matrix material often called a resin solution. There are many different polymers available depending upon the starting raw ingredients. There are several broad categories, each with numerous variations. The most common are known as polyester, vinyl ester, epoxy, phenolic, polyimide, polyamide, polypropylene, PEEK,
Gramophone Company mechanical patents that he owned, which patents were valuable in the agreement with Columbia. Thus, Victor and Columbia began making flat records in the U.S., with UK Gramophone and others continuing to do so outside the U.S. This left Edison the only major player in the making of cylinders; Columbia still made a limited number for a few years. Emile Berliner went out of the business. All he had left were the masters of his earlier records. These he took to Canada and reformed his Berliner label in Montreal, where he used the "His Master's Voice" trademark. Edison would soon
