Patent ID: 8449711

Claim:
Method for manufacturing a vehicle trim panel that comprises the following steps: a. Dosing at least the following components: Polyolefin Fibre reinforcement Additives, Wherein at least one part of the polyolefin is pre-mixed with the additives to form a concentrate, and wherein the additives comprises at least one foaming agent, b. Heating and homogenising the components used in step a to produce a homogeneous mixture of the components, c. Producing a sheet made from the homogeneous mixture of components produced in step b, d. Heating, cross-linking and foaming the sheet produced in step c, e. Cutting the foamed sheet product produced in step d to produce a first sheet of foam, f. Pre-heating the first sheet of foam, g. Cold forming at least the first sheet of foam, h. Covering at least the first sheet of foam by applying a second sheet of covering that corresponds with at least one of upper and lower faces of the first sheet of foam, i. Cutting the trim panel that is produced to remove the surplus material, characterized in that the foaming of the sheet of step d is carried freely in such a way that when foaming of the sheet occurs, there are no physical elements in contact with said sheet which hinder the free three dimensional expansion of the sheet, and in that, the reinforcement fibre is accumulated in zones closest to the upper and lower surfaces of the first sheet of foam.
