Products in Prepregs & Molding Compounds: Thermoset Polyimide (PI)

HexTool® M61 Tooling Compound is randomly layered strips of uni-directional prepreg which is consolidated into rolled goods. It can be utilized as multi-ply quasi-isotropic hand lay-up, and subsequently CNC milled to close tolerance. HexTool® has proved to be dimensionally stable with the ability to hold vacuum integrity before and after machining, and after more than 500 part cure cycles. Fabricated from Hexcel’s BMI resin HexPly® M61, HexTool® tools are ideally suited for 180°C (356°F) cure carbon fiber tools. This makes them lighter weight, more energy efficient than tools made of steel or Invar®, and more cost-effective with tighter mold tolerance than standard composites.

Renegade Materials Corporation RM-3004 prepreg products offer an Out of Autoclave (OOA) option for processing BMI’s. This very unique chemistry can be processed into low-void, high quality, thick laminates with only a vacuum bag in the oven. Yet it still delivers excellent hot/wet performance and durability in airframe, missile and propulsion applications at service temperatures up to 400°F (204°C). RM-3004 (OOA) BMI delivers comparable damage tolerance at high temperatures to industry-standard Autoclave Processed BMI’s. Although developed for structural applications, RM-3004 also offers some unique advantages for tooling. Renegade precision-quality prepregs exhibit excellent handling characteristics and are available in woven and unidirectional form on various fibers including carbon, quartz and S2 glass. A wide variety of nano-materials can be incorporated into this resin system for tailored laminate properties and multi-functional performance. Renegade has formulated compatible BMI Paste Adhesive products (RM-3006, RM-3007) for use with RM-3004 prepregs. Renegade also offers BMI resin systems for RTM (RM-3000) or VARTM (RM-3010) infusion processing.

Hexcel tooling fabrics are produced from high-performance bismaleimide (BMI) resin and carbon fiber utilizing Hexcel’s proprietary PrimeTex® spreading technology. PrimeTex® fabrics are inherently more uniform as the filaments in each tow are spread creating a closed fabric with lower interstitial porosity and reduced resin rich regions normally seen in other tooling fabrics. The resulting tooling surface enables quality part production with less post cure processing of finished part surfaces.
