Examples of how the guide can help are in scenarios such as those where one must determine if a Precision Board low- temperature (PBLT — contin- uous to 200°F) or Precision Board high-temperature (PBHT — continuous to 300°F) product is needed. The information in the Guide's chart represents PBLT and PBHT densities ranging from 4-75 lb/ft 3 , used in a variety of applications, including signage, sculpture, theme parks, tooling, prototypes and autoclave tools. precisionboard.com » THERMOSET RESINS & ADHESIVE SYSTEMS Covalent bonding aerospace adhesive Solvay (Alpharetta, GA, US) has launched FusePly, a new bonding technology designed specifically for use in prepreg-based aerospace composites fabrication applications. Solvay developed FusePly to enable the build of reliable, bonded composite parts using conventional manufacturing processes, through the creation of covalently bonded structures, thus offering the potential for eliminating the need, in terms of part certification, to ensure sufficient bond strength through the use of rivets or other fasteners. The adhesive reportedly addresses the manufacturing challenges faced by aircraft builders looking for improved perfor- mance, build rates and lightweighting. Solvay contends that FusePly offers users a clear step-change in bonding performance and resulting benefits: • Improved reliability: Through the creation of chemical bonds, it reportedly enables part manufacturers to have increased confidence in bonded structures. • Higher part performance: Compared to mechanical fasteners, FusePly offers higher performance because drilling holes into fiber-reinforced structures introduces structural damage and creates stress concentrations that ultimately reduce the load capacity of the part. • Lightweighting: The reduction and replace- ment of fasteners with FusePly bonding will substantially reduce the overall weight of the aircraft. • Greater design freedom: Adhesives offer much greater design flexibility in terms of manu- facture and assembly at lower cost. FusePly, Solvay maintains, can easily be integrated into existing manufacturing processes as an upgrade for conventional surface preparation methods. solvay.com NEW PRODUCTS
