Compared with state-of the-art composite materials favored by the other players on the ice, the age-old wooden material dampens the sting of vibrations more effectively, making it simply more comfortable for goalies to wield a wooden stick.
In Flint, Mich., Kettering University undergraduate student Linda Hunt studied the way goalie sticks respond to impacts along with her adviser, Daniel Russell. Presented earlier this month at the meeting of the Acoustical Society of America in San Diego, the project quantified a feeling often expressed by many goalies playing at higher levels….
Most NHL goalies use wooden sticks, officials from the Carolina Hurricanes and Columbus Blue Jackets said. Hurricanes equipment manager Bob Gorman explained that one of their goalies does use a composite stick, primarily because it weighs less than a wooden one.
The energy of a frozen puck traveling 100 mph is quickly absorbed by the thick padding of a goalie’s leg pads. But the sticks—wooden or composite—are not as forgiving. The puck transfers its energy to the stick, which vibrates violently.
