Abstract
Molds for preparing a viscoelastic material for dynamic analysis that include mold sections that when closed in alignment define such elements as a specimen cavity having an open end and dimensioned to provide a sample of the viscoelastic material of a predetermined size. Other elements may include a support member holder adjacent to the open end of the specimen cavity and a fill channel in fluid communication between the specimen cavity and a fill port. The fill port is adapted for receiving a reactive mixture of the viscoelastic material to fill the specimen cavity, wherein the support member holder is adapted for securing a support member having a surface that seals the open end of the specimen cavity.
Claims20
A mold for preparing a viscoelastic material for dynamic analysis, the mold comprising:
- mold sections that when closed in alignment define elements comprising:
- a specimen cavity having an open end, the specimen cavity dimensioned to provide a sample of the viscoelastic material of a predetermined size;
- a support member holder adjacent to the open end of the specimen cavity;
- and
- a fill channel in fluid communication between the specimen cavity and a fill port, the fill port adapted for receiving a reactive mixture of the viscoelastic material to fill the specimen cavity, wherein the support member holder is adapted for securing a support member having a surface that seals the open end of the specimen cavity.
A mold for preparing a viscoelastic material for dynamic analysis, the mold comprising:
- mold sections that when closed in alignment define elements comprising:
- two cavities, each of the cavities having adjacent proximal open ends and opposing distal open ends, the cavities dimensioned to provide dual samples of the viscoelastic material of a predetermined size;
- a center support member holder extending between the adjacent proximal open ends of the cavities;
- a first support member holder and a second support member holder, each adjacent to each of the opposing distal open ends of the cavities;
- and
- a fill channel in fluid communication between the cavities and a fill port, the fill port adapted for receiving a reactive mixture of the viscoelastic material to fill the cavities, wherein the center support member holder is adapted for securing a center support member having a center support surface that seals the proximal open ends of the specimen cavity and the first support member holder and second support member holder are each adapted for securing a first support member and second support member respectively, having a first and a second support surface respectively that seals the distal open ends of the specimen cavity.
A method for preparing a viscoelastic material for dynamic analysis, the method comprising:
- preparing a bonding surface of a support member for bonding the viscoelastic material thereto;
- securing the support member in a mold, wherein the prepared bonding surface of the support member borders an open end of a specimen cavity in the mold and wherein the specimen cavity is dimensioned to provide a sample of the viscoelastic material of a predetermined size;
- filling the specimen cavity with a reactive mixture of the viscoelastic material;
- curing the reactive mixture to form the viscoelastic material;
- and
- removing the support member from the mold with the viscoelastic material bonded thereto.
