Abstract
A manufacturing method includes: in a loom, weaving a woven reinforcing fibre fabric including a plurality of reinforcing fibre tows and polymeric material; and heating the woven reinforcing fibre fabric as it exits the loom to cause the polymeric material to melt and/or cure.
Claims18
A manufacturing method comprising:
- in a loom, weaving a woven reinforcing fibre fabric comprising a plurality of reinforcing fibre tows and polymeric material comprising a plurality of thermoplastic yarns, wherein weaving comprises weaving the plurality of reinforcing fibres tows and a plurality of thermoplastic polymer yarns together in the loom to form the woven reinforcing fibre fabric, wherein:
- (a) each thermoplastic polymer yarn has a linear density no less than 110 dtex and/or no greater than 330 dtex;
- and/or
- (b) the woven reinforcing fibre fabric comprises no less than 1.0 wt. % and/or no greater than 8.0 wt. % thermoplastic polymer yarn;
- and;
- heating the woven reinforcing fibre fabric as it exits the loom to cause the polymeric material to melt and/or cure.
3 more elements
Weaving apparatus comprising:
- a loom for weaving a woven reinforcing fibre fabric;
- a heat source configured to heat the woven reinforcing fibre fabric as it exits the loom;
- and
- a tensioner for applying tension to the woven reinforcing fibre fabric as it exits the loom, wherein the tensioner comprises a rotatable mandrel configured to receive and draw the woven reinforcing fibre fabric away from the loom.
