Flame retardant for thermosetsAt its booth, Ciba Corp. (Newport, Del.) will promote its MELAPUR 200 halogen-free flame retardant (melamine polyphosphate) for thermoset composites. Reported benefits of the product include reduced smoke and corrosivity, synergy with other flame retardants and the ability to maintain critical properties of the formulation. It decomposes endothermically above 350°C/662°F, acting as a heat sink to cool the polymer. The released phosphoric acid forms a coating that shields the polymer substrate. The phosphoric acid further reacts with the polymer to form a char and inhibit the release of free radical gasses into the oxygen phase. Simultaneously, nitrogen species released from the degradation of melamine intumesces the char to further protect the polymer. Ciba also will conduct a survey regarding thermoset flame retardancy and smoke requirements in the transportation and building and construction markets. The survey is designed to identify new opportunities and guide future flame retardant developments in these industries. Survey participants will have the chance to win an iPod Touch.

ATL/AFP simulation softwareCG Tech (Irvine, Calif.) will demonstrate its VERICUT Composite Applications Suite at the show (center photo, at right). The suite consists of machine-independent offline programming and simulation software for automated composite tape and fiber-placement CNC machines. It consists of two separate applications: VERICUT Composite Programming (VCP) and VERICUT Composite Simulation (VCS). VCP reads CAD surfaces and ply boundary information and adds material to fill the plies according to user-specified manufacturing standards and requirements. Layup paths are linked together to form specific layup sequences and are output as NC programs for the automated layup machine. VCS reads CAD models and NC programs, either from VCP or other composite layup path-generation applications, and simulates the sequence of NC programs on a virtual machine. Material is applied to the tool via NC program instructions in a virtual CNC simulation environment. The simulated material applied to the form can be measured and inspected to ensure the NC program follows manufacturing standards and requirements. A report showing simulation results and statistical information can be automatically created. See CG Tech in Booth 301.
