JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC Europe 2014 - A laser-based heating system has been developed for use with both thermoplastic and thermoset automated fibre placement (AFP) equipment.
The system utilizes a high-power laser and specialized optics to precisely heat carbon fibre prepreg, significantly improving upon the capabilities of hot gas and infrared lamp based equipment. Real-time monitoring of the composite surface temperature allows for a complete record of the manufacturing process.Combined with a near-instantaneous response time, the composite temperature can be held within ±10°C. This results in a more predictable product with less variability and uncertainty. Since the laser beam has a precise perimeter and an extremely high heating efficiency, the heat-affected zone is minimized, further enhancing part quality and improving processing speed by two to three times.Targeted at high-temperature, high-speed AFP, the laser heating system is available as an option on new Automated Dynamics AFP work cells or as a retrofit onto other AFP machines.More information: www.automateddynamics.comBooth: M63b
