Abstract (en)

[origin: WO2012056381A1] A process for manufacturing a manhole cover having a thickness of at least 10 mm, and up to 80 mm, comprising the generation of a mixture of reagents able to generate a polymeric thermosetting material, the mixing of suitable reinforcement fibres, the introduction into an open mould of the mixture thus obtained, the closure of the mould with a suitable counter-mould, the hardening of the said mixture, the opening of the mould, and the removal of the manhole cover obtained. The process makes use of the co-injection of reagents for the generation of the polymeric thermosetting material and the reinforcement fibre. The present invention also describes a manhole cover obtained with the said process.
