METHOD AND DEVICE FOR PRODUCING PULTRUDED MATERIAL

Document Type and Number:

WIPO Patent Application WO/2018/008431

Kind Code:

A1

Abstract:

Provided are a method and a device for producing a pultruded material that improve the homogeneity of a thermosetting resin. The device (100) for producing a pultruded material comprises a first opening section (112), a second opening section (113), a closing section (114), a tension-applying section (115), an impregnating section, and a mold (140). The first opening section (112) and the second opening section (113) open a bundle of reinforcing fibers (24''') and thereby obtain a bundle of reinforcing fibers (24'). The closing section (114) closes the bundle of opened reinforcing fibers (24') and thereby obtains a bundle of reinforcing fibers (24). The tension-applying section (115) applies tension along the direction in which the reinforcing fibers (24) extend to the bundle of reinforcing fibers (24) that pass through the closing section (114). The impregnating section impregnates the bundle of reinforcing fibers (24) with a thermosetting resin (26). The mold (140) pultrudes the bundle of reinforcing fibers (24) that have been impregnated with the thermosetting resin (26).
