摘要:
In a process for the manufacture of composite material comprising a matrix of set inorganic binder (e.g. Portland cement) and reinforcing fibre (e.g. carbon fibre), by de-watering a slurry containing water-settable inorganic binder, reinforcing fibre and web-forming fibre (e.g. cellulose fibre), and subsequently setting the binder, a ball clay is included in the slurry that is de-watered, in order to reduce shrinkage of the composite material during setting of the binder.
