Technical Datasheet Panex® 35 Chopped Fiber (Type -13) Flake-Type Chopped Carbon Fiber Description Panex® 35 Flake Type chopped fibers provide ready impregnation of thermoset resins, with the capability to mold complex shapes. The resultant carbon fiber/ resin matrix composites offer high strength-to-weight and stiffness-toweight ratios. Panex® 35 Flake Type chopped fibers may also be used as a low-cost alternative in thermoplastic applications, whereby a small portion of the matrix-specific product can be replaced with chopped flake carbon fibers with negligible impact to composite properties. Recommended Use Thermoset resins: Epoxy, Vinyl Ester, Unsaturated Polyester, and Phenolic. Applications Automotive, aerospace, chemical industry, construction, military, sporting goods.
