JR Technology - Composite test and repair specialists and production engineers

These Bolster and Contour Bags are designed to withstand temperatures in excess of 200°C, depending on the grade ordered.  They are filled with an insulation which conforms to the components shape and offer an alternative to preparing special tools and contour boards for supporting parts during repair or patch curing operations.  The bolsters are double skin protected, having a reinforced outer cover suitable for the temperature range specified.

JRTL supply standard units, but also provide a tailoring service for specific components and profiles.

These high temperature resistant blankets are used to retain heat when performing manufacturing or repair operation.  They ensure that heat losses are minimised at the points where required when either using integral heating or individual heater mats.  The blankets are manufactured from a variety of soft woven materials with impermeable surfaces as required. These range from a combination of polyester and glass to aramid, quartz and ceramic textiles.  The filling is generally a mineral fibre or granular material giving a quilted thickness range of 100 - 150 mm.
