System for manufacturing a composite fibre structure

A system for manufacturing by electrospinning a composite fibre structure;

• wherein the system comprises:
• a first device of solution electrospinning comprising
• a first head with a first nozzle, the first head being configured to be biased to a first voltage, and
• a pump in fluid communication with such first head;
• a second device of melt electrospinning comprising
• a second head with a second nozzle, the second head configured to be electrically connected to ground, and
• heating means and an extruder in fluid communication with such second head;
• a collector arranged spaced apart from the first and second heads, wherein the collector is configured to be either electrically connected to ground or biased to a second voltage;
• and
• switching means configured to selectively assign the electrical status of the collector so that:
• when the first device is operating, the collector is electrically connected to ground so that there is a first voltage difference between the first head and the collector;
• and
• when the second device is operating, the collector is biased to a second voltage so that there is a second voltage difference between the second head and the collector.
