Embodiment 1

[0021] A vertical pultrusion forming process for multi-layer fiber composite laminated profiles. A tubular mandrel 1 is used to arrange longitudinal fiber bundle laminations on the tubular mandrel 1 first, and then arrange circumferential fiber bundle laminations on the longitudinal fiber bundle laminations. The method of fiber bundle layup alternately arranges longitudinal fibers and hoop fibers on the tubular mandrel 1, and the fiber composite layup is formed by stacking longitudinal fiber bundles and hoop fiber bundles, and is drawn by a tractor 7 traction movement;

[0022] Introduce part of the glue into the interior of the tubular mandrel 1 and let the glue flow out of the tubular mandrel 1 into the interior of the fiber composite laminate and inject glue from the interior of the fiber composite laminate into the fiber composite laminate. At the same time, another part of the glue flows from the The fiber composite laminate is injected with glue to make the glue soak int...

Abstract

The invention relates to a vertical pultrusion process of a multilayer fiber composite laminated section bar, which comprises the steps of: arranging longitudinal and circular fibers on a tubular core die to form a fiber bundle laminated fiber composite laminate and tracting to move; introducing one part of glue into the fiber composite laminate and injecting, injecting the other part of glue from the outer part of the fiber composite laminate to ensure that the glue dips the fiber composite laminate; and finally, heating for forming and cooling. A pultrusion device comprises a tracting machine used for tracting the fiber composite laminate and a heating forming die, wherein the heating forming die is provided with an internal and external injection device, a tubular core die is arranged on the internal and external injection device, an internal injection hole of the internal and external injection device is connected with one pipe mouth of the tubular core die, the other pipe mouth of the tubular core die and an external injection hole of the internal and external injection device are connected to an injection pump, at least one group of yarn distributors are sleeved on the tubular core die and comprise a longitudinal yarn coil and a circular yarn winder, and the longitudinal yarn coil is positioned in front of the circular yarn winder along the traction direction.

Description

technical field [0001] The invention relates to a pultrusion forming process and device for profiles, in particular to a vertical pultrusion forming process and device for internally and externally injected multi-layer fiber composite laminated profiles. Background technique [0002] The production methods of on-line weaving or winding fiber-reinforced thermosetting plastic profiles announced so far are difficult to achieve multi-layered and multi-oriented lamination of fiber bundles due to the limitations of their process layout and fiber impregnation methods, and there are pollution to the environment, and the glue is easy to oxidize and difficult to produce. control deficiencies. Contents of the invention [0003] The invention provides a vertical pultrusion forming process and device for a multi-layer fiber composite laminated profile that can guarantee and improve the quality of the profile. [0004] The present invention adopts following technical scheme: [0005] ...
