COMPOSITE STRIPS, COMPOSITE MATERIALS, AND METHODS FOR MANUFACTURING COMPOSITE STRIPS

Abstract

The invention relates to a composite reinforcing strip, a composite reinforcing strip (1) comprising: a covering (2) surrounding several longitudinal channels (3, 4) developed in parallel with the longitudinal development direction (X) of the composite reinforcing strip (1) and arranged in order between opposite ends (a) of the composite reinforcing strip (1); several longitudinal reinforcing fibers (3a) arranged inside the reinforcing channels (3) of several longitudinal channels (3, 4); and several longitudinal permeable fibers (4a) arranged inside at least one permeable channel (4) among several longitudinal channels (3, 4). The covering (2) has, at least on the upper surface (2a) of the covering (2) opposite the lower surface (2b) of the covering (2), several surface pores (5) leading to at least one permeable channel (4) to determine the fluid communication between several longitudinal permeable fibers (4a) and the external environment. The invention also relates to composite materials including composite reinforcing strips and a method for producing composite reinforcing strips.
