Problems solved by technology

[0005] These measures increase the weight and cost
Additionally, through-thickness reinforcement tends to reduce in-plane strength (reinforcing fibers cause stress concentrations), so more material is still required to achieve the required strength, further adding to weight and cost

Embodiment Construction

[0041] The composite material according to the present invention comprises a multilayer component with one layer on top of another layer. Each layer of components includes one group (m) of parallel strips on top of the other group.

[0042] It should be pointed out that "a layer (group) on top of another layer (group)" should not be understood only literally, because adjacent multilayer components are interlaced and adjacent groups of stripes are interlaced Yes, as you can see from below.

[0043] Each group will be made by a specific method of placing parallel bars in batches.

[0044] figure 1 A schematic diagram with a horizontal array H1-H11 and a vertical array V1-V11 pattern is shown. The angle between the horizontal and vertical arrays is 90°. The figure 1 Used together with Figure 2 to explain how two (m=2) sets of strips can be used to make a layer of components.

[0045] For the basic manufacturing of a one-layer module, first, according to the vertical arrays V1, V3, V5,...

Abstract

A method is presented for making a composite material from strips comprising longitudinal fibres and a binder or resin, which material comprises a number of layer assemblies one on top of the other. Each layer assembly comprises m sets (with m at least 2) of parallel strips each extending in a different direction, Each layer assembly is manufactured by successive steps of depositing groups of parallel strips according to a well defined pattern (without longitudinally interweaving strips with previously deposited strips). Before completing a layer assembly, with the exception of the last layer assembly, by depositing its last group of parallel strips, the first group of parallel strips of the following layer assembly is already deposited. A composite material manufactured with such a method is presented too.

Description

Technical field [0001] The invention first relates to a method of manufacturing a composite material from a strip comprising longitudinal fibers and a binder or resin. Background technique [0002] This method is called automatic fiber / tow arrangement. It generally uses a material usually composed of tapes or strips (which are usually called "tows" or "slit tapes", including longitudinal fibers and a binder (or resin)). The individual strips or tows are manipulated to form a strip of material that is placed on the tool. Composite material strips or tows are used to build layer by layer, and the angle at which each layer ("ply") is placed on the tool is precisely determined by the fiber placement process. [0003] Automatic fiber / tow placement enables the construction of complex composite structures using controlled or curvilinear fiber paths. This method of producing composite structures is more cost-effective than manual methods. Because this method has the ability to orient f...
