Abstract
Inversion liners are provided which in a first embodiment include first and second flexible fabric layers separated by one or more glass fiber containing layers and joined in tubular form. The second flexible fabric layer further is bonded to a third flexible fabric layer comprising a substantially fluid impermeable layer. An invertible glass-faced liner is also provided by this invention which includes a glass facing on one side and a substantially fluid impermeable layer on the other. The substantially fluid impermeable layer is joined to a flexible fabric layer which is preferably heat bonded to a thin veil joined to a second glass containing layer of this liner embodiment. The inversion liners of this invention can be built-up in multiple layers or blocks to meet end-use design demands while still providing flexural moduli in excess of 500 ksi, preferably about 700-800 ksi.
