Mikrosam (Prilep, Macedonia) said at JEC Americas 2014 that its new Li3000 series of impregnation lines for prepregging incorporate a sophisticated means of measuring both dry fabric weight and final prepreg weight. Expected to help prepreggers maintain far greater quality control and meet tighter specifications for customer prepregs, the Li3000 features new resin mixing and delivery systems that constantly monitor mix ratios, gauge the quantity of resin applied to the web and the resin’s viscosity via a digitally controlled closed system, managed from a single touch panel. Fresh mixing of resin is triggered when the set viscosity threshold is reached. Mikrosam says it also can provide climate-controlled enclosures for resin-mixing operations where prevention of prepreg moisture absorption is critical.
Mikrosam also touted its new MFP 2000 NC8 automated fiber placement (AFP) machine, which reportedly combines the cost advantages of tape laying with the high precision of AFP. The company said it has delivered one system already to a European civil aircraft OEM for manufacturing single-aisle jetliners and will deliver a second system in October.
