Problems solved by technology

[0003] The preparation is time-consuming, especially because of the long processing times when baking the parts in an oven
Costly finishing steps such as grinding and polishing the edges are often also required
[0004] But since the particularly lightweight design plays an important role in the bike, accept the drawbacks associated with it

Embodiment Construction

[0060] figure 1 The provision of a fiber composite mat 3 for a lightweight structure 1 comprising a plurality of hollow chambers 2 as in a first method step is shown in a schematic side view.

[0061] In this case, the fiber composite mat 3 is applied both on the upper side and on the underside of the lightweight structure 1 .

[0062] A heated roll 4 is used for this, whereby the fiber composite mat 3 is applied by calendering.

[0063] A fiber composite mat 3 impregnated with thermoplastic is used in this example. The thermoplastic is heated above Tg on rollers 4 and the fiber composite mat 3 is joined to the lightweight structure. It will be appreciated that multiple fiber composite mats are preferably applied superimposed as layers (not shown).

[0064] figure 2 The material thus produced is shown in a schematic side view.

[0065] It consists of a core of the lightweight structure 1 and each of two fiber composite mats 3 , 5 .

[0066] The fiber composite mats 3 ,...

Abstract

The invention relates to a method for producing a component having a light-weight structure (1). According to the invention, impregnated fiber mats (3,5) are applied to a light-weight structure (1) that comprises hollow chambers (2).

Description

technical field [0001] The present invention relates to a method of making parts from composite materials. In particular, the invention relates to the preparation of components for bicycle accessories, such as saddles and bicycle shoes, and to the preparation of bicycle components, especially bicycle frames. Background technique [0002] In order to provide lightweight structures for bicycles, fiber-reinforced composite materials, especially carbon fiber-reinforced composite materials, are used in practice. In particular bicycle frames are produced from carbon fiber reinforced plastics. [0003] The preparation is complex, in particular because of the long processing times when the parts are baked in an oven. Costly finishing steps such as grinding and polishing the edges are often also required. [0004] However, since a particularly lightweight design plays an important role in bicycles, the disadvantages associated with this are accepted. [0005] Purpose of the inve...
