Embodiment 1

[0023] In this embodiment, the raw material is a mixture of surface fiber fabrics, including two-dimensional fabric material scraps such as plain weave, twill weave, satin weave, and multi-axial cloth. The fiber is at least one of polyester fiber, carbon fiber, polyester fiber, glass fiber, cotton fiber, aramid fiber, hybrid fiber, hybrid fiber, and composite fiber. This embodiment adopts figure 1 The equipment shown performs integrated processing and production, figure 1 in:

[0024] Shearing machine 1:

[0025] It is used to process the recycled surface fiber into a longitudinal strip fiber with a certain width according to the proportional size requirements;

[0026] Shearing machine 2:

[0027] Used to cut the longitudinal strip fibers of the shearing machine 1 into block fibers again in the transverse direction according to a certain required size;

[0028] Fiber splitter 3:

[0029] It is used to split the lumpy fibers of a certain size cut into by the shearing machine 2 to spl...

Embodiment 2

[0041] The loose short carbon fiber raw material made through the process of step a-f of Example 1 is made into an areal density of 50g / m 2 A fiber felt with a certain needle-punch density, which is then compounded to prepare composite parts such as automobiles.

Embodiment 3

[0043] The loose short carbon fiber raw material made through the process of step a-f of Example 1 is made into a fiber content of 300g / m 2 The prepreg felt with a certain needle punch density. The prepreg felt can be directly made into various composite material components through the hot pressing process.

[0044] The core of this patented technology is that no matter what kind of flat fiber leftovers, it can be cut into fixed-length fiber sheets by linkage, and then the fiber is dispersed and recycled to form a loose and certain length. This kind of short fiber material is processed into fiber non-woven felt, fiber needled felt, fiber felt prepreg, SMC, BMC and other products.

[0045] Linkage cutting is to perform a fixed-length cutting in one axial direction for the planar fiber leftover material according to the required length; then, to the above-mentioned already cut fiber strips, perform secondary continuous fixed-length cutting in the direction perpendicular to the first ...

Abstract

The invention discloses a planar fiber leftover material recycling and reusing method and relates to the planar fiber recycling field. By the adoption of the planar fiber leftover material recycling and reusing method, for multiple kinds of planar fiber leftover materials, the integrated technology of cutting the planar fiber leftover materials into fiber sheet materials of a fixed length in a linkage manner, conducting fiber dispersing machining and recycling to form a short fiber material which is loose and fluffy and has a certain length, machining the short fiber material into fiber non-woven felt, fiber punched felt, fiber felt prepreg, SMC, BMC and other products can be adopted. The planar fiber leftover material recycling and reusing method is high in production efficiency and capable of achieving large-scale production, the recycled short fiber is used for manufacturing punched fiber felt or non-punched fiber felt, and the performance of the punched felt or non-punched fiber felt is better than that of the same type of products and is approximate to that of a brand new fiber product. The recycled raw materials are wide in source, and low in cost, the planar fiber leftover material recycling and reusing method is suitable for weaving manners of multiple kinds of raw material fabric, the requirement for the raw materials is low, and cost is saved beneficially.

Description

Technical field [0001] The invention relates to the field of planar fiber recycling, and in particular to a method for recycling planar fiber scraps and a preparation method thereof. Background technique [0002] Planar fiber is a type of fiber material that is widely used in industry. Planar fiber includes carbon fiber, glass fiber, aramid fiber, hybrid fiber or other fiber two-dimensional fabric, carbon fiber single-sided cloth with hot melt lines, multi-axial Cloth, stitching cloth and stitching felt etc. These fabrics include plain weave, twill weave, satin weave, multi-axial, unidirectional, various fiber combination fabrics and other structural forms. Usually, after these fabrics are mechanically or manually cut or trimmed according to the size of the product, a large number of leftovers of different sizes and lengths remain, because the size of the remaining leftovers cannot meet the size requirements of the composite parts. , and cannot be used by composite parts, ...
