Transcript of Lacrosse Helmets
in the 1928 Olympics... Made For Impact The shells of lacrosse helmets are now made of injection-molded plastic such as ABS (acrylonitrile butadiene styrene) plastic. Some helmets also are made of the same plastics as motorcycle helmets, such as polycarbonate plastics. The facemasks, on the other hand, are made of strong, lightweight metals like titanium and steel. The inside of the shell is lined with a polypropylene or other foam padding. the chinstrap is made of leather and vinyl. Origin of Titanium Discovered by William Gregor in 1791, titanium frequently appears in our daily lives. Used in joint replacements, planes, and firearms, titanium is a relatively familiar material. Being an element, titanium not made out of any raw materials, but is often found in igneous rocks. Titanium can be fond in North America, Norway, South Africa, the Ukraine, and Australia. Bibliography "Lacrosse Helmet-The Importance of Choosing the Best." Johan Friedman. Ezine Articles, n.d. Web. 5 Dec. 2012. History of Lacrosse Helmets Lacrosse helmets were first in used in 1928 during the Olympics in Amsterdam. Based on the materials used in sports helmets of that time, the first lacrosse helmets were probably made of leather and string. Since then, helmets have evolved greatly. Sometime during the 1960's, plastic helmets were introduced.
Later, in 1988, helmets started to take on a better shape as injections molding was introduced, and now advancements in design and protection are flowing.
Not one person in particular can take credit for the invention of the lacrosse helmet, but many inovators include Cascade, Warrior, and Brine. Connor Smeader
Period 7 ...Since then, the design and materials
of lacrosse helmets have evolved greatly Function Lacrosse helmets are used to protect the wearer from injuries. A facemask on the front protects the wearer from being hit in the face with anything. The plastic shell both protects the wearer from being hit with something and acts as a cushion in the event of a collision.
A chinstrap holds the helmet securely in place. Then... ...Now Why These Materials? These materials are chosen for their strength and weight, mainly. Titanium, used in facemasks, has a low density, is strong, and is very resistant to corrosion. If you were to be wearing a helmet with a facemask made of a soft metal like gold and took a hit to the face or fell on your face, the facemask would not protect you very well. ABS plastic, one of the possible plastics used for the shell, is a polymer plastic, making it able to stand up to the wear and tear that accompanies lacrosse. (Bucket Helmet) "Heritage--LAX."
