Measurement of properties of sample of curing compositions under high pressure

摘要

A method for testing a curing composition, comprising includes a curing composition; injecting the curing composition into a mold; curing the curing composition into a cured composition, in the mold at a controlled curing pressure; measuring at least one physical or mechanical property of the cured sample at a controlled test pressure, in the mold; the mold being rigid relatively to the cured sample during the curing step.

1. A method for testing a curing composition, the method comprising:
(a) providing a curing composition; (b) injecting the curing composition into a hollow body of a mold so that the curing composition contacts the hollow body, the hollow body having a main axis and comprising:
a flexible internal layer radially deformable to the main axis when subjected to a controlled test pressure; anda rigid external wall adapted to be in contact with the flexible internal layer in a removable way; (c) curing the curing composition into a cured sample, in the mold, at a controlled curing pressure; (d) wherein the flexible internal layer is not capable of deforming radially to the main axis when subjected to the controlled curing pressure during the curing step due to the support of the rigid internal wall; (e) removing the rigid external wall; and (f) measuring at least one physical or mechanical property of the cured sample at a controlled test pressure, in the mold.
