^M4\M ^PB|#' WW Uni-Directional Prepreg Tapes Germanischer Lloyd Approved, Approval No. WP Ì 030030 HH Medium-to-High Areal Weight Carbon Fiber Prepregs for high-volume commercial applications Zoltek produces uni-directional (UD) prepreg tapes based on Panex carbon fiber. Zoltek prepreg is ideal for large-volume composite applications where high production throughput, excellent composite properties, and low material cost are important. A wide selection of epoxy resin formulations meets most processing and composite property require- ments for tack, toughness, flow in cure, surface finish, cure- time, cure temperature, and delivered composite strength and modulus. Custom formulations are also available. Zoltek prepreg properties, such as fiber areal weight (FAW), resin content, and width, are readily adjusted to exactly meet customer requirements. Packaging options include core size, interleaf type (paper and/or poly film) and number (one side or two), and custom labeling. Zoltek prepreg production is geared to large volumes and low cost Special projects are welcomed. Recommended Use Any article or component benefiting from the unique properties of carbon fiber composites. Excellent for hand lay-up or automated fabri cation processes. Applications Wind energy, automotive, petroleum production, aviation, marine, industrial, other transportation, medical (including X-ray), sports and Zoltek Uni-Directional Prepreg Tapes 'Production efficiency and pricing may be impacted by tape and width selection ** Maximum roll size is 1,000 lbs net prepreg weight Zoltek Corporation | 3101 McKelvey Rd. | St. Louis, MO 63044
