Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] see as figure 1 As shown, the technical solution adopted in this specific embodiment is: it comprises 0 ° layer 1, chopped yarn layer 2, +45 ° layer 3, 90 ° layer 4, diversion sandwich layer 5, -45 ° layer 6, surface Layer 7; the 0° layer 1, the chopped yarn layer 2, the +45° layer 3, the 90° layer 4, the diversion sandwich layer 5, the -45° layer 6, and the surface layer 7 are arranged in sequence from top to bottom.

[0020] Further, the 0° layer 1, +45° layer 3, 90° layer 4, and -45° layer 6 are reinforced fiber material layers, which can be high-performance glass fiber, carbon fiber, aramid fiber, etc.

[0021] Further, the air-guiding sandwich layer 5 is an organic fiber needle-punched or chemically bonded felt.

[0022] Further, the chopped strand layer 2 is high performance glass fiber chopped strand.

[0023] Further, the surface layer 7 is thin glass...

Abstract

The invention discloses a three-dimensional preformed composite fiber and a machining process thereof, and relates to the technical field of textiles. The fiber comprises a 0-degree layer, a short cut yarn layer, a +45-degree layer, a 90-degree layer, a guide sandwich layer, a - 45-degree layer and a surface layer, wherein the 0-degree layer, the short cut yarn layer, the +45-degree layer, the 90-degree layer, the guide sandwich layer, the minus 45-degree layer and the surface layer are arranged from top to bottom in sequence. By adopting the fiber, the stability of a glass fiber / carbon fiber textile can be greatly improved, the tensile strength of the textile can be also improved, the textile is relatively high in bending strength, the product pass percent is greatly increased, and relatively good practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a three-dimensional preformed composite fiber and its processing technology. Background technique [0002] Fiber reinforced material is a new type of composite material with excellent properties such as light weight, high strength, corrosion resistance, heat preservation, insulation, sound insulation, and waterproof. The traditional molding process is a manual process of mold opening, which has low production efficiency, high cost, serious environmental pollution, great harm to the human body, and poor product performance: the bonding effect of resin and fiber is poor, and it is easy to produce various defects such as air bubbles and dry spots. affect the mechanical properties of the product. [0003] With the society's high requirements for energy saving, improving work efficiency, and environmental friendliness, the continuous development of the molding process of resin-based...
