PROCESS FOR MANUFACTURING A SHAPED OBJECT THROUGH FILAMENT WINDING

The invention pertains to a process for manufacturing a shaped object through a winding process comprising the steps of - winding resin-containing fiber under tension to form a shaped fibrous object, the resin comprising at least 50 wt.% of polyester derived from an aliphatic polyol with 2-15 carbon atoms and an aliphatic polycarboxylic acid with 3 to 15 carbon atoms, calculated on the polymer constituents of the resin, - subjecting the shaped fibrous object to a curing step. In one embodiment, the resin-containing fibers are provided through a process comprising the steps of - contacting fiber with a liquid resin composition, the resin composition comprising polyester derived from an aliphatic polyol with 2-15 carbon atoms and an aliphatic polycarboxylic acid with 3 to 15 carbon atoms, to obtain resin-containing fibers, - subjecting the resin-containing fibers to a drying step, the drying step being carried out until the resin-containing fibers are tacky and the resin-containing fiber has a diluent content of at most 25 wt.%, calculated on the weight of resin composition in the resin-containing fiber. Tacky fibers obtainable by this intermediate process are also claimed, as is the shaped fibrous object that can be obtained by the process according to the invention.
