Vacuum Consumables The range of vacuum consumables has been designed for use in a wide range of vacuum bag processes. Such processes include autoclave/ prepreg curing, wet lay-up, low temperature oven/ prepreg processes and infusion processes. Gurit has selected a specific range of products which are particularly suitable for working with Gurit's epoxy prepreg and laminating systems where they are regularly used for the curing of large composite structures at temperatures up to 150°C. Sealant Tapes Sealant tape is used to seal the tool to the vacuum bag in order to provide an airtight seal. The tapes are tacky to ensure a positive seal is achieved against a variety of tool surfaces. Peel Plies Peel plies are fine weave fabrics which are applied to the laminate stack to provide a clean, contaminant-free textured surface, suitable for secondary bonding, filling or painting. Our range is green in colour. Release Films Release films are used to separate and release the laminate from the vacuum stack following the cure of the component. These films are perforated to allow a certain bleed of resin from the laminate into a breather material such as Econoweave 44W. Breather Fabrics / Meshes Breather fabrics are used to absorb excess resin (bleed) from a laminate which is being cured under vacuum. The fabric also allows the air, or any volatiles, to be evacuated prior to, and during the cure cycle. Vacuum Bagging Films Vacuum bagging films are used to effectively seal the whole of the area of the composite laminate to be cured. Self-Adhesive Mould Release Materials Self-adhesive mould release materials are used to cover moulds as an effective alternative to the use of release wax or liquids. Flash / Release / Shrink Tapes Flash tapes are used to locate vacuum consumable materials or to mask off areas to be painted, sanded or to prevent damage. Some of these tapes have release qualities so they can be used as tool repair tapes if necessary. Shrinktapes are used to consolidate specific components.
