Abstract (en)
[origin: CA2790263A1] The invention relates to a method, a system and a resin sheet for producing fiber-reinforced molded parts (SMC) by means of extrusion in a molding press (20) from a fiber-reinforced resin sheet (10) which is continuously produced in a flat web installation (16). According to the invention, at least one resin base layer (5, 8) is combined with fibers (6) in a mixing device (1), is subsequently mixed in a fulling and saturating device (14) and is finally matured in a thickening device (25) to form a continuous resin sheet (10), wherein said continuous resin sheet (10) is cut to form cut sheets (18) and is then transferred, either directly or joined in a structure (36) with other cut sheets (18), by means of a transfer device (19) to a tool (35) of a molding press (20) in which it is then pressed to form a fiber-reinforced molded part (21). The invention is in particular characterized in that means for reinforcement are applied on at least one resin base layer (5, 8) for forming a reinforcement zone (39) which is delimited in length and/or width relative to at least one resin base layer (5, 8) before joining the resin base layers (5, 8).
