Abstract
A shock absorbing member 50 having a ceramic bonded body 15 having: a plurality of first sheet-like members 5 each having a ceramic containing 60 mass % or more of boron carbide and each having a thickness of 0.1 to 50 mm; and a bonding layer arranged between the first sheet-like members 5 adjacent to each other, the bonding layer bonding surfaces to be bonded facing each other of the first sheet-like members adjacent to each other, wherein the bonding layer has a bonding material containing at least one metal selected from the group consisting of aluminum, copper, silver, and gold.
Claims9
A shock absorbing member comprising a ceramic bonded body comprising:
- a plurality of first sheet-like members each comprising a ceramic that comprises boron carbide in an amount of 60 mass % or more, and each having a thickness of 0.1 to 50 mm;
- and
- a bonding layer arranged between the first sheet-like members adjacent to each other, wherein the bonding layer bonds surfaces of the first sheet-like members facing each other and being adjacent to each other,
- wherein the bonding layer comprises a bonding material comprising at least one metal selected from the group consisting of aluminum, copper, silver, and gold,
- the adjacent first sheet-like members bonded to each other with the bonding layer are integrated,
- from 2 to 1000 sheets of the first sheet-like members are laminated in a thickness direction of the sheet-like members,
- the ceramic bonded body has a flexural strength of 100 MPa or higher when measured by a four-point bending method, and
- a plurality of voids are formed in the bonding layer at an interface between the first sheet-like member and the bonding layer.
