Method for manufacturing filler-containing compositions with a specific curing regimen

A method for manufacturing a filler-containing composite object, the method comprising the steps of

• providing a composition comprising a filler and a polymer, wherein the polymer is a polyester derived from an aliphatic polyol with 2-15 carbon atoms and an aliphatic polycarboxylic acid with 3 to 15 carbon atoms, the polyester having an extent of polymerization, which is the ratio of the fraction of functional groups that have reacted to the maximum of those functional groups that can react, in the range of 0.1-0.8, and
• subjecting the composition to a curing step, in which the composition is subjected to high-frequency heating for a period of 10 seconds to 30 minutes, at a pressure of at most 1.106 Pa (10 bar), resulting in the formation of a composite object, wherein high-frequency heating is carried out by subjecting the composition to an alternating electromagnetic field with a frequency in the range of 3-100 MHz.
