This communication includes two parts corresponding to separate topics.
Part one is concerned with a definite aspect of the mechanical performance of the new windshield, namely its resistance to aging and more precisely to abrasion during a normal use.
This study is conducted in two directions: the first one comprises a fundamental evaluation of the comparative weakening effect on safety glasses resulting from, either a well defined single scratch, either a friction or impact of solid abrasive particles.
The second one, definitely more pratical, is directed towards the study of the wipers aging effect on the impact resistance of the conventional and the new V.H.R. windshield.
Part two is concerned with the biomechanical behaviour of the new windshields evaluated by impact tests of an anthropomorphic dummy positioned in a full scale modified car accelerated up to 30 mph and undergoing simulated barrier crashes.
These experiments have been carried out by a team led by Professor Patrick at Wayne State University, Detroit (U.S.A.).
Dynamics of the impacts have been recorded with three high speed motion picture cameras.
Fundamental parameters such as deceleration peak, impact duration, severity index and laceration index have been measured.
These various studies have been achieved by comparing the new V.H.R. windshield with the conventional car safety glasses.
