A FIBER-IMPREGNATING SYSTEM, A PULTRUSION DEVICE AND A METHOD OF PRODUCING COMPOSITE MATERIAL OF PULTRUSION

摘要

The present invention relates to a fiber-impregnating system, comprising an infusion box provided with a mold cavity that has an infusion cavity for fibers to pass, an infusion hole for resin infusion, and a resin passage for communicating with the infusion cavity and the infusion hole, wherein the mold cavity further includes a compression segment 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. The fiber-impregnating system of the present invention is suitable not only for the fabrication of a pultrusion product with fiber felt/textile, but also for the fabrication of composite material of pultrusion made all from unidirectional fiber yarn.
