Abstract
A rigid multilayer decorative surface covering is proposed. The surface covering has a thickness and comprises a sandwiched reinforcement composite layer comprising a thermoplastic polymer matrix having a top and a bottom surface, the sandwiched reinforcement composite layer comprising reinforcement layers on the top and bottom surfaces. The sandwiched reinforcement composite layer has a thickness comprised in the range from 25% to 85% of the thickness of the rigid decorative surface covering. A method for manufacturing the rigid multilayer decorative surface covering is also disclosed.
