Document Type and Number:
WIPO Patent Application WO/2017/144532
Kind Code:
A3
Abstract:
The present invention relates to a fiber-impregnating system, comprising an infusion box (100) provided with a mold cavity that has an infusion cavity (102) for fibers to pass, an infusion hole (103) for resin infusion, and a resin passage (107) for communicating with the infusion cavity and the infusion hole, wherein the mold cavity further includes a compression segment (104) upstream of the infusion cavity, the compression segment having an entrance with a depth greater than or equal to a depth of its exit, the depth of the entrance and exit of the compression segment ranging from 0 to 2 mm. Moreover, the present invention also relates to a pultrusion device provided with the said fiber-impregnating system, and a method of producing composite material of pultrusion with the pultrusion device.
