Radar Ski Materials

Discovering the marriage between new designs and the advancements in available materials long drove Herb O’Brien. Never satisfied with ‘the way it’s always been done,’ Herb knew that it was a symbiotic relationship between the two components that really created the magic. New materials allow for innovative developments in design, and vice versa. It's at the Radar Lab where we discover what is possible and bring our new ideas to light. Every concept that ends up in a Radar ski is born here and every Vapor is hand-produced in this special place that Herb built. From Radar Lake to lakes around the world, yours included, we hope you enjoy the ride.

The Textreme Spread Tow Carbon Advantage

  • Higher Strength-to-Weight Ratio
    Spread tow carbon allows for a denser packing of fibers with fewer overlaps and gaps, maximizing the amount of load-bearing fiber in the composite.

  • Reduced Fiber Crimp
    In standard weaves, the crossing of fibers (crimp) can lead to stress concentrations and reduced mechanical properties. Spread tow fabric, being flatter, minimizes crimp, which enhances stiffness and tensile strength.

  • Improved Resin Distribution
    A more uniform fabric structure facilitates even resin flow during curing. This reduces voids in the resin, resulting in a more consistent and reliable composite material.

  • Lighter Weight
    By optimizing the carbon fiber layout, you reduce excess resin. The result is a lighter, faster ski. 

The PMI (polymethacrylimide) Foam Core Advantage

  • Higher Strength-to-Weight Ratio
    PMI foam has superior mechanical properties at a lower density, contributing to a stiffer, yet lighter structure than other popular materials. When every gram counts, this is a crucial advantage. 

  • Improved Compressive and Shear Strength
    PMI foam can better withstand compressive and shear loads, ensuring the core maintains its integrity under stress. This is particularly important in the fast-moving, high-stress slalom ski environment. 

  • Enhanced Thermal Stability
    PMI foam offers better thermal performance by maintaining its properties in a wider range of temperatures. This is beneficial when operating in dynamic environments (think hot sun, cool water.).

  • Superior Bonding with Composite Skins
    The particular cellular structure of PMI foam promotes strong adhesion with carbon fiber. This ensures a more consistent and durable bond than with alternative foams.
