Embodiment 1

[0035] A winding molding method for FRP, said molding method comprising the following steps:

[0036] The first step is the preparation of raw materials. First, check whether the fibers meet the requirements, and then dry them in an oven at 80°C for 16 hours;

[0037] The second step is to configure the glue solution, and firstly weigh each component;

[0038] The third step is to check the equipment, open the winding machine for idling, and check the operation of the system;

[0039] The fourth step is to clean the mandrel, first use sandpaper to polish the mandrel surface, and then clean it with ethyl acetate;

[0040] The fifth step is winding and forming, pouring the glue into the glue tank; then dividing the fibers into two parts equally, passing one of the fibers through the dipping tank and extrusion roller, and then dividing the dipped fibers into several groups , and then bundled through the yarn splitting device, and then wound according to the set line shape. When...

Embodiment 2

[0048] A winding molding method for FRP, said molding method comprising the following steps:

[0049] The first step is the preparation of raw materials. First, check whether the fibers meet the requirements, and then dry them in an oven at 100°C for 18 hours;

[0050] The second step is to configure the glue solution, and firstly weigh each component;

[0051] The third step is to check the equipment, open the winding machine for idling, and check the operation of the system;

[0052] The fourth step is to clean the mandrel, first use sandpaper to polish the mandrel surface, and then clean it with ethyl acetate;

[0053] The fifth step is winding and forming, pouring the glue solution into the glue tank; then dividing the fibers into two parts evenly, passing one of the fibers through the dipping tank and extrusion roller, and then dividing the soaked fibers into several groups , and then clustered through the yarn splitting device, and then wound according to the set line ...

Abstract

The invention belongs to the technical field of glass steel molding and particularly relates to a glass steel winding molding method which comprises the following steps: I, preparing raw materials; II, preparing a glue liquid; III, inspecting equipment; IV, cleaning a core mold; V, performing winding molding, pouring the glue liquid into a glue trough, equally dividing a fiber into two parts, feeding one part of the fiber through a glue soaking tank and a glue extrusion roller, dividing multiple glued fibers into a plurality of groups, further feeding through a fiber division device, bundlingthe fibers, winding according to a set wire shape, firstly winding a layer of fibers which are not soaked into the flue, secondly winding a layer of the glued fibers, winding in sequence alternatively, adjusting a gluing device at any time to control the glue quantity on the fibers, scraping off excessive glue at any time when the fibers are wound, observing fiber ordering situations, measuring thicknesses, and powering off a machine when design requirements are met; VI, performing curing; VII, performing demolding.

Description

technical field [0001] The invention belongs to the technical field of FRP molding, and in particular relates to a winding molding method of FRP. Background technique [0002] FRP is also called GFRP, that is, fiber reinforced plastics, which generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, glass fiber or its products as reinforced plastics, called glass fiber reinforced plastics, Or called fiberglass. [0003] The concept of composite material refers to a material that cannot meet the requirements of use, and needs to be combined by two or more materials to form another material that can meet people's requirements, that is, a composite material. For example, although a single glass fiber has high strength, the fibers are loose and can only bear tensile force, but cannot bear bending, shearing and compressive stress, and it is not easy to make a fixed geometric shape, so it is a soft body. If they are bonded together ...
