Embodiment Construction

[0049] figure 2 A schematic cross-sectional view of a clamping jaw 5 is shown, which clamps an embodiment of a blow moulding core system 10 according to the invention.

[0050] The blow molding core system 10 here includes a blow molding core 12 and a reinforcement element 14.

[0051] The reinforcement element 14 has a base body 16 and a plurality of support elements 18 projecting from the base body.

[0052] The supporting element 18 is of needle-shaped configuration and protrudes from the base body 16 in a star-shaped manner.

[0053] In addition, the support element 18 is movable. Alternatively or in addition, it can be provided that the support element 18 is flexible.

[0054] The base body 16 has a smooth cross section. The supporting elements 18 are uniformly arranged around the entire circumference of the base body 16.

[0055] Here, the length of the supporting element 18 is determined such that the tip of the supporting element 18 reaches the inner wall of the blow molding c...

Abstract

The invention relates to a reinforcing element (14), for at least part of the hollow fiber composite material component ware, the reinforcement element includes at least one substrate (16) and multiple out from the substrate support element (18). The invention also relates to a kind of blow molding core system, which include hollow blow molding core (12) and the invention of reinforcing components. The invention also relates to a use under the condition of the hardened components used to make at least part of the hollow fiber composite component method.

Description

Technical field [0001] The present invention relates to a reinforcement element for reinforcing a blank of an at least partially hollow fiber composite material component, a blow molding core system and a method for manufacturing an at least partially hollow fiber composite material component. Background technique [0002] Various core systems are required to manufacture hollow components. In addition to the foam system remaining in the component, a blow-molded core is also used here, which is removed again after the injection process, that is, after the matrix material has been injected and the component has hardened. [0003] In fiber-reinforced components, the fibers are usually arranged on the core by means of braiding technology after the core is manufactured. The removable blow molding core is a hollow body, which can be filled with pressure-loaded ambient air or liquid, such as water, during the braiding process. [0004] A resin transfer molding (RTM) process can then be pe...
