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,

Fonotipia continued to operate into the electrical recording era, which commenced in 1925–26, by which time the company had been absorbed into Odeon records. The records made by Fonotipia are prized by collectors and musicologists for their high technical quality, and for the high artistic merit and interest of much of what was captured for posterity. The Fonotipia catalogues were reconstructed, so far as then possible,
