A pressure transmitter for use in the curing of composite components may take the form of a caul plate, pressure intensifier or vacuum bag and is formed from a curable elastomeric material which is partially cured, normally when supported on a mold, at a temperature not exceeding 100.degree. C. It is subsequently further cured at, for example 175.degree. C., while unsupported. It may incorporate a reinforcing layer formed from a curable resin pre-impregnated fibrous material.

1. A pressure transmitter for use in the production of composite components, the pressure transmitter comprising an inner region of a curable prepreg reinforcement in the form of resin pre-impregnated fibers defining a plurality of interstitial spaces and an outer region of an elastomeric material which enters into the interstitial spaces, the resin of the prepreg reinforcement being partially curable at a temperature not exceeding 100.degree. C. and subsequently further cured at a temperature of at least 170.degree. C.
