Light weight POLYESTER fabric
150g/m2, non-woven, polyester breather fabric has excellent elongation and drapability.
It is ideally suited to oven and lower pressure autoclave processes.
Breather fabrics are essential air flow media, which provide a flexible pathway through which the air and volatile gasses can be successfully removed. They enable an even vacuum level across the component surface i.e. they prevent localised air entrapment – “lock off”.
Breather Fabrics generally are of a non-woven construction, which allows the fabric to stretch and conform to complex shapes, and are supplied in various synthetic materials, in a choice of weights depending upon the process temperature and pressure requirements.These same fabrics can also be utilised as a “bleeder” layer during component cure to absorb any excess resin.
