Glass fibre reinforced material mfr. - uses bonding adhesive to secure parallel fibre strands to nonwoven carrier

摘要

In the mfr. of a reinforced material, parallel strands of glass fibre are bonded to a non-woven felting of unorientated staple fibres, using an adhesive bonding agent to hold the layers together. The parallel fibre strands are laid longitudinally, horizontally or at an angle of about 45 degrees on the carrier fabric. Two layers of glass fibre strands can also be used, with the strands in one layer being at about 90 degrees to the strands in the other layer, and the layer(s) are clad on both sides by a matting of glass fibre staple. The application of the adhesive bonding aent is by passing through a bath of the bonding agent. The carrier fabric is developed in strip or belting form with the layer of parallel glass fibre strands being applied and moved with the carrier strip.
