Problems solved by technology

[0006] Israel Patent #75426 of DU PONT DE NEMOURS AND CO and #36522 of FOSTER GRANT CO INC propose significant improvements, but these designs are limited to specific forms of cells or profiles, and according to their basic material constraints on the choice of material pairs (pairs), and more importantly, their 3D-volume orientation strength cannot be predetermined

Embodiment approach 1

[0051] Such as figure 1 As shown in , this embodiment consists of component segments with unidirectionally oriented strands 1 of reinforcement material, supported by connections 2 between the strands. The distance A between the determined connection points is equal to (or smaller than) the Euler critical length. This configuration of the material resists the compressive forces exerted on the wire 1 and prevents buckling in the direction of the X-axis. That is, the wire cross-section (and corresponding weight) required to withstand compressive forces in the Z direction is drastically reduced (by as much as 5-100 times) compared to a solid wall construction of equivalent flexural resistance . That is, resistance to compressive forces in the Z direction achieves strength suitable for wire compression. In this case, the additional weight at the connection point 2 may be 5-20 times smaller than the weight of the solid bonding material connected proportionally to the critical len...

Embodiment approach 2

[0053] figure 2 A component segment structure formed from dense unidirectional mold-filled boron wires 21 is represented. The line 21 connected to the connection point 22 is produced by using ammonium supply at a temperature in excess of 800°C. Subsequently, the lines connected between them and on the outer surface 23 create a protective layer of boron nitride. The construction must withstand tension in the Z direction (centrifugal force), bending in the X & Y directions (gas pressure), and the possibility of a separate external wire on the side opposite to the direction of the gas pressure because of the gas force of the bend. A preferred form of such component construction for this application (turbine blade) may be constructed as follows:

[0054] 1. Unidirectional boron can withstand a higher force (for boron protected by boron nitride) at a high temperature of 1150°C, that is, an increase of 250-300°C. An increase in turbine blade temperature would lead to an increas...

Embodiment approach 3

[0062] image 3 Is a part fragment cross-sectional view showing the structure of a single oriented reinforcement thread supported by a bond material with a foam structure. Such as image 3 As shown in , the present embodiment consists of strands 31 of unidirectional reinforcing material supported by connection points 32 and housing walls 34 filled with gas between the strands. The distance A between the defined connection points is equal to (or below) the critical (Euler) length-Young's modulus and the wire diameter D for this type of material. This configuration resists compressive forces applied to the wire 31 and prevents buckling in the directions of the X-axis and Y-axis. That is, the wire cross-section (and corresponding weight) required to withstand compressive forces in the Z direction is drastically reduced (by as much as 5-100 times ). That is, the resistance to compressive force in the Z direction may have the compressive strength of the wire. In this case, t...

Abstract

Improved composite structure comprises threads distributed within disperse matrix. The structure has increased strength by virtue of distance between the points of support of the thread span, which is deliberately selected to be less than the distance corresponding to the critical lengths corresponding to buckling. The structure is suitable for various articles of manufacture requiring improved the strength-to-weight or rigidity-to-weight ratio in various directions.

Description

technical field [0001] The present invention relates to novel internal structures for components comprising composite structures. More specifically, the present invention relates to component internal structures. On the one hand, the structure adjusts the material 3D strength of the component according to the spatial distribution of the load (adoption), on the other hand, it reduces the content of the bonding material as much as possible, and increases the moment of inertia of the component without causing structural bending damage ( buckling damage), and reduce the density to increase the specific strength or rigidity. As a result, the structure proposed by the present invention enables improved strength-weight or stiffness-to-weight ratio in all directions, strength and especially stiffness (including bending) parameters. [0002] The invention further provides a production method of the proposed part structure, which enables the product to have 3-dimensional orientation s...
