摘要:
The present invention relates to a new method for producing composite material (1) provided with a finishing surface (12) and a backing surface (13), which comprises the following steps: step (i), contact heating of at least one blanket layer (11) that includes natural fibres mixed with synthetic fibres, or heating up to at least a temperature at which the synthetic fibres soften; step (ii), placing of the blanket layer (11) heated in step (i) in the cavities of a mould, followed by pressing; step (iii), cooling of the blanket layer (11) moulded in step (ii) to at least a temperature at which the finishing surface (12) hardens; step (iv), injection of plastic resin to form recesses or structural portions in predefined regions in the backing surface (13); and step (v), cooling of the assembly obtained in step (iv) to at least a hardening temperature.

A description is given of a new product composed of natural and synthetic fibres, and also processes for producing a material for structural use that consists in the following steps: (i) arranging at least a first blanket 11 and at least a second blanket 11', each of which is composed of natural and synthetic fibres and of at least one intermediate layer 12 based on olefins, between the first blanket 11 and the second blanket 11', in order to obtain the required geometry; (ii) heating, compression and adhesion of the assembly obtained in step (i); and (iii) cooling of the assembly obtained in step (ii) to at least a hardening temperature.
