Abstract
A compound material including fibers which are embedded in a thermoplastic matrix has a free surface to be treated. The material has one or more capillary spaces extending between the fibers, which spaces are at least partly formed by communicating pores and which are open towards the free surface. An average diameter of the pores is greater than, equal to or not substantially less than the fiber diameter.
Claims14
A compound material, comprising:
- a thermoplastic matrix;
- and
- a plurality of fibers embedded in the thermoplastic matrix,
- wherein at least one capillary space having an opening oriented toward a surface of the compound material is formed in the thermoplastic matrix between fibers of the plurality of fibers, the at least one capillary space further having an average diameter that is substantially equal to or larger than an average fiber diameter of the plurality of fibers.

A reinforcing structure comprising:
- a plurality of layers of a compound material welded together, wherein each layer comprises:
- a thermoplastic matrix;
- and
- a plurality of fibers embedded in the thermoplastic matrix, and
- wherein, a layer of the plurality of layers that is located at a surface of the reinforcing structure includes at least one capillary space having an opening oriented toward a surface of the compound material is formed in the thermoplastic matrix between fibers of the plurality of fibers, the at least one capillary space further having an average diameter that is substantially equal to or larger than an average fiber diameter of the plurality of fibers.
