Carbon Fiber Molding Compounds – Enabling Ultimate Performance in Demanding Applications
Carbon fiber molding compounds represent the premium tier of SMC and BMC technology, offering exceptional strength-to-weight ratios, fatigue resistance, and dimensional stability for the most demanding aerospace, automotive, and industrial applications. While carbon fiber reinforcement significantly increases material costs, it delivers performance characteristics that cannot be matched by glass fiber alternatives.
Understanding Carbon Fiber Molding Compounds
Carbon fiber molding compounds are available in both SMC and BMC formats. Recent research has developed novel carbon fiber mat-based SMC materials using pseudo-thermoplastic resins to address environmental concerns and enable recyclable composite materials. Toray's Toray Cetex MC1322 is a thermoplastic bulk molding compound based on PEKK thermoplastic resin with carbon fibers up to 25.4 mm in length.
