Adhesive Fiberglass Tape
Glass fiber grid tape for fixation of fiber layers and core materials
What is the function of glass fiber grid tape in the lamination process?
In vacuum-assisted processing, the grid tape serves to position and hold fabrics, core materials, or auxiliary materials such as perforated release film, peel ply, or breather fabric in place. It is applied before the laminate layup to specific areas in the mold or on top of the layers and maintains the alignment of materials during the vacuum build-up and infusion process. Its open grid design allows resin to pass through, which may be beneficial in vacuum infusion or similar resin transfer processes. The adhesive is compatible with common materials such as fiberglass, carbon fiber, and foam cores.
Which version is offered by HP-Textiles?
HP-Textiles offers the glass fiber grid tape HP-AM075/050, which features a width of 50 mm, a roll length of 90 m, and a weight of 75 g/m². The double-sided adhesive coating is applied to a reinforced fiberglass mesh, combining mechanical stability with user-friendly handling during the laminate assembly.
How is the grid tape used?
The adhesive tape is applied along the desired position and lightly pressed down. Fiber mats, reinforcement fabrics, core materials, or release film layers can then be fixed onto the tape. It remains in the laminate stack during the resin infusion and curing process, and – depending on part requirements – may remain inside the final laminate. This makes it suitable for setups where precise positioning is needed while maintaining resin flow permeability through the material.
Application areas of glass fiber grid tape
The glass fiber grid tape can be used in various areas of composite processing – such as in mold making, prototype construction, lightweight component manufacturing, boatbuilding, model making, or the production of sandwich structures. It is compatible with vacuum infusion processes using epoxy (EP) or unsaturated polyester (UP) resins. The material properties allow integration with other vacuum consumables used in composite fabrication setups.
