Glass article for automotive interior having improved head form impact testing performance

A glass article for a vehicle interior system, comprising:

• a glass sheet comprising a first major surface and a second major surface, the second major surface being opposite to the first major surface;
• a support member comprising a first support surface and a second support surface, the second support surface being opposite to the first support surface, wherein the glass sheet is disposed on the first support surface;
• and
• a mounting element disposed on the second support surface of the support member, wherein the mounting element comprises a plurality of mounting brackets configured for attachment to the vehicle interior system;
• wherein, when the glass article is subjected to headform impact testing according to FMVSS 201, the headform does not exceed 80 g deceleration continuously for more than 3 ms;
• and
• wherein the glass sheet deflects less than 50 mm when subjected to the headform impact testing.

A method of manufacturing a glass article, the glass article comprising a glass sheet having a first major surface and a second major surface, a support member having a first support surface and a second support surface, and a mounting element, the method comprising the steps of:

• adhering the second major surface of the glass sheet to first support surface of the support member;
• wherein the mounting element is attached to the second support surface of the support member;
• wherein the support member comprises a first Young's modulus (E1) in GPa and a first yield strength (Y1) in MPa, wherein E1≥471.288*exp(−0.0294*Y1)+10 for a first yield strength (Y1) from 39 MPa to 520 MPa and wherein E1≤1.941e5*exp(−0.0336*Y1)+48 for a first yield strength (Y1) from 223 MPa to 520 MPa;
• and
• wherein the mounting element comprises a second Young's modulus (E2) in GPa and a second yield strength (Y2) in MPa, wherein E2≥605.1203*exp(−0.0303*Y2)+3.9 for a second yield strength (Y2) from 10 MPa to 950 MPa and wherein E2≤765.0928*exp(−0.0094*Y2)+85 for a second yield strength (Y2) from 78 MPa to 950 MPa.
