IPO Watch listed CFOAM, Ltd. as the 4th most successful IPO on the Australian Stock Exchange in 2016. Touchstone is proud of this spin out company and the team that took the company public. CFOAM has invested substantially in to increase production in the original CFOAM manufacturing plant. https://ipowatch.com.au/blog/2017/1/8/ipo-winners-losers-2016
In 1988, Touchstone was in the middle of a multi-year R&D program to develop the world's best ingot mold cast iron material. In those days, molten steel was poured in these molds to produce steel ingots. Ingot molds have been widely replaced by continuous casters - although companies like Centre Foundry in Wheeling, West Virginia, continue to produce ingot molds for the specialty alloy industry.
During the development, Touchstone was asked to produce this video to explain the importance of graphite flakes in the performance of the ingot mold and to let the personnel who produce the iron that their involvement is critical to the quality of their product.
Recording video images in scanning electron microscopes was not so common in the 1980's...
Touchstone recently won a contract to develop a next-generation carbon fiber. This technology is expected to have a number of advantages over current state-of-the-art carbon fibers produced from rayon.
About carbon fibers: Carbon fibers are extremely strong and stiff. The tensile strength of carbon fiber is typically 500,000 pounds per square inch (3.5 Gpa). For comparison, 4143 steel, which is used for bicycle frames and automobile structures, has a tensile strength of 125,000 pounds per square inch and 2420-T3 aluminum, which is used for building aircraft, has a tensile strength of 65,000 pounds per square inch. Carbon fiber has the stiffness of steel and about three times the stiffness of aluminum.
Add to this that carbon fiber composites are about 1/5th the weight of steel and about half the weight of aluminum. Carbon fiber composites are a big deal and they are beginning to have a huge impact on our daily lives.
Touchstone has a long history of developing new materials including CFOAM carbon foam, stainless steel cut nails, aluminum brazing alloys, discontinuously reinforced metals and many others.
The carbon fiber development work is being funded by the Missile Defense Agency through its Small Business Innovation Research program with Phase 1 funding at $100,000.
