Dr. Karl Alfred Grosch (1923-2012) was a rubber industry scientist noted for his contributions to understanding tire friction[1] and abrasion.
[2] Dr. Grosch is the developer of the LAT 100 Abrasion tester that is used widely in the tire industry to evaluate the friction and wear properties of rubber compounds.
Grosch was born in Trannroda [de], today An der Heide 11, 07387 Krölpa/Trannroda Thuringia, Germany, on February 16, 1923, died July 15, 2012.
Grosch helped establish that rolling friction and grip on dry roads are governed by the viscoelastic properties of rubber.
After retirement, he developed the LAT 100 laboratory friction and abrasion tester, which is marketed by VMI Holland BV in the Netherlands.
