Dow Plastics has developed a new pultrusion process technology for the production of continuous fibre thermoplastic composites called FULCRUM.
According to Chris Edwards, marketing development manager for Dow, profiles pultruded with FULCRUM thermoplastic composites have many times the strength of any other thermoplastic seen before. “These profiles have extremely high mechanical properties and excellent toughness and damage tolerance,” says Edwards. “In addition, profiles can be processed at very high speeds, and are able to be post formed, and are also recyclable.”
Historically, Edwards notes, thermoplastic composites have lacked the mechanical properties of thermoset composites, primarily because of poor fibre impregnation and poor fibre adhesion. Edwards says the use of Dow’s engineering thermoplastics polyurethanes, ISOPLAST, in FULCRUM composite materials, provides a suitable thermoplastic matrix to overcome these limitations. The table below compares advantages of thermoplastic vs. thermoset composites
Higher processing speed
Lower environmental impact
Higher damage tolerance
Higher transverse properties
Longer shelf life in matrix
Better ignition resistance
Better corrosion resistance
Better creep resistance
