Embodiment Construction

[0039] figure 1 An example of the component 1 of the present invention is shown. The part 1 is made of an organic matrix composite material, which contains an organic matrix densified fiber reinforcement. The organic matrix is ​​present in the pores of the fiber reinforcement and covers and binds the fibers of the reinforcement. The combination of fiber reinforcement and organic matrix forms an organic matrix composite, which consists of Figure 1-4 The symbol 10 in .

[0040] Fiber reinforcements can have various structures. For example, fiber reinforcements may be formed from stacks of fiber textures, such as two-dimensional fabrics or unidirectional layers, or from fabrics obtained by three-dimensional weaving. The fibers forming the fiber reinforcement may be carbon fibers, fibers of a ceramic material other than carbon (eg silicon carbide or aluminum oxide), glass fibers or polymer fibers.

[0041] The organic matrix of the part 1 can be a solid thermoplastic polymer...

Abstract

The present application relates to a component (1) made of an organic matrix composite material having, on its surface (S), a wear-resistant region (20) comprising a resin (24) comprising polytetrafluoroethylene particles (22).

Description

technical field [0001] The present invention relates to a part made of an organic matrix composite material ("organic matrix composite"; "OMC") and the manufacture of the part, which part has improved wear resistance. Background technique [0002] Organic matrix composites are typically used where the parts are in frictional contact with each other. Common matrices for structural composites with organic thermoset or thermoplastic matrices have relatively high coefficients of friction. The contact and friction encountered in operation can generate significant heat generation and wear. [0003] It is known to introduce carbon fillers in the polymer matrix, but even with this solution the coefficient of friction of the parts obtained may remain high. The abrasion resistance provided by this solution can therefore be further improved. [0004] Therefore, there is a need for a solution to improve the wear resistance of parts made of organic matrix composites, while keeping the...
