Embodiment Construction

[0050] figure 1 A flow diagram of a method 100 for producing a hybrid composite part using a particular apparatus according to the present invention is shown.

[0051] In step 101 of method 100, a mold body having an inner mold cavity is provided. The temperature of the mold body corresponds to the polymerisation temperature of the reactive thermoplastic precursor to be injected. The mold cavity in the mold body is defined by the inner mold walls. In some examples, the reactive thermoplastic precursor may be polymerized at room temperature, while in other examples, the polymerization temperature will be above room temperature. The geometry of the mold cavity will define the shape and geometry of the resulting molded part. For example, the mold body includes an upper mold and a lower mold. The mold body contains heating cylinders, other heating devices, which are inserted into it and distributed in the mold body.

[0052] In step 102 of method 100, a fiber preform is placed ...

Abstract

The invention describes a method and a system for producing hybrid composite parts,. Disclosed is a mould body provided with a mould cavity that has at least one male and one female portion. In this cavity, a fiber preform is placed, being located in at least one area of the mould cavity and leaving free at least other area of the mould cavity. This mould body, also, is at the polymerization temperature of a reactive thermoplastic precursor. After placing the preform into the mould cavity, the mould body is closed. At this point, the reactive thermoplastic precursor is injected into the mould cavity. When the mould cavity is completely filled and the reactive thermoplastic precursor polymerized, the resulting hybrid composite part is demoulded.

Description

technical field [0001] The present invention provides a method and system for producing hybrid thermoplastic parts using RTM (Resin Transfer Molding) technology. In particular, the present invention provides a method and system for producing hybrid composite parts in which at least a portion of the molded composite part includes a polymer matrix reinforced by a fiber preform and at least another portion includes only the polymer matrix. [0002] The invention is widely applicable in various industries, such as the production of automotive or aerospace components. Background technique [0003] The use of glass fibers, carbon fibers, aramid or other fibers to reinforce thermoplastic parts is well known in the art. Two technologies for producing fiber-reinforced thermoplastic parts are RTM and organo sheet compression molding (impregnation of prefabricated strip sheets with continuous fibers). [0004] Thermoplastic RTM can be used to produce composite parts reinforced with r...
