Abstract The fracture of a bronze object is usually accompanied by localized deformation.The deformed part often tends to spring back at an unpredictable moment after its shape is corrected.The reconstruction of the area adjacent to the damage should be sufficiently resistant to the stress derived from springback so that the whole structure can remain stable.

However, the choice of gap-filling materials for bronze objects is typically based on personal experience, and there are few available studies on their pertinent properties.The present study focused on a typical situation of deformation, took the flexural modulus as a crucial parameter and explored iphone 13 pro max price florida the development of a protocol for selecting a gap-filling material for bronze restoration in terms of its mechanical property.The flexural modulus was measured for the main classes of materials in cyspera cream where to buy use, and the factors related to preparation that influenced performance were studied.

Among the various materials tested, carbon fiber reinforced (CFR) materials exhibited an advantageous value of the modulus and notable operational convenience.Further tests were conducted to assess their chemical safety for application in a museum context, as well as their surface workability.After obtaining overall encouraging results, composites reinforced with CF cloth and chopped CF were applied to the reconstruction of different parts of an archaeological bronze vessel.

Indications for future improvement in the experimental setup and some practical notes regarding the use of CFR materials were also provided in this paper.
