Problems solved by technology

But the shortcoming of this method: the one, synthetic resin is used more; The 2nd, labor intensity is high; Harmful and prone to air pollution
This method of making FRP products is only suitable for products with relatively thick walls, that is to say, it is limited by the thickness not less than 3 cm, and the strength of this product is low

Embodiment 1

[0019] As shown in Figure 1, the fiber laminate composite product of this embodiment is composed of a chopped glass fiber layer 1, a polypropylene fiber needle felt 2, a glass fiber warp layer 31 and a glass fiber weft layer 32 through a polyester sewing thread 4 It is sewn together in one go. The materials of the glass fiber warp layer 31 and the glass fiber weft layer 32 are both glass fiber rovings. The thickness of the fiber layer composite product is 10mm-15mm.

[0020] The manufacturing process of the fiber layer composite product of the present embodiment is as follows:

[0021] ① The polypropylene fiber is elasticized, carded, laid, and needle-punched to form a polypropylene fiber needle-punched felt 2 . The single fiber diameter of polypropylene fiber is 90μm, which has good elasticity. During this process, the porosity should be controlled at 70%.

[0022] ② Warp the polyester stitched thread 4 through a high-speed warping machine to form a warp beam.

[0023] ③...

Embodiment 2

[0030] As shown in FIG. 2 , the fiber layer composite product of this embodiment is made of glass fiber chopped strand mat 1 , polypropylene fiber needle felt 2 and carbon fiber cloth 3 through one-time stitching of polyester stitching thread 4 . The thickness of the fiber layer composite product is 5mm-10mm.

[0031] The manufacturing process of the fiber layer composite product of the present embodiment is as follows:

[0032] ① The polypropylene fiber is elasticized, carded, laid, and needle-punched to form a polypropylene fiber needle-punched felt 2 . The single fiber diameter of polypropylene fiber is 80μm, which has good elasticity. During this process, the porosity should be controlled at 80%.

[0033] ② Warp the polyester stitched thread 4 through a high-speed warping machine to form a warp beam.

[0034] ③ Send the glass fiber chopped strand mat 1 to the stitching mechanism through the mesh belt.

[0035] Simultaneously, the polypropylene fiber needle-punched felt...

Embodiment 3

[0040] The rest of this embodiment are the same as Embodiment 2, the difference is:

[0041]The fiber laminate composite product of this embodiment is formed by one-time stitching of glass fiber continuous mat 1 , polyester fiber needle mat 2 and glass fiber warp knitted fabric 3 through polyester stitching thread 4 . The thickness of the fiber layer composite product is 2 mm to 5 mm.

Abstract

The invention discloses a fiber layer shape composite product and a production method thereof. The fiber layer shape composite product is composed of superposition and connection of a glass fiber layer, synthesized fiber needling felt and a reinforced fiber layer. The synthesized fiber needling felt is positioned in the middle of the glass fiber layer and the reinforced fiber layer. The production method is that: 1. the synthesized fiber needling felt is produced with porosity of 50 to 90 percent and a single fiber diameter of 80 to 100Mum; 2. the polyester hemming-stitching thread is warped into a warp beam; 3. the glass fiber layer, the synthesized fiber needling felt and the reinforced fiber layer are sent into a hemming-stitching mechanism, and the polyether hemming-stitching thread is sent into the hemming-stitching mechanism by a frequency conversion automatic let-off mechanism; 4. in the hemming-stitching mechanism, layers of the materials are hemming-stitched into the fiber layer shape composite product only one time. The fiber layer shape composite product of the invention is applicable to the closed mold forming techniques such as RTM and VARTM, etc. which has the advantages of being easy to design, simple technique and high work efficiency.

Description

technical field [0001] The invention relates to a reinforcing material for glass fiber reinforced plastics, in particular to a fiber laminated product and a manufacturing method thereof. Background technique [0002] FRP is a composite material composed of reinforcing materials and matrix materials, also known as glass fiber reinforced plastics, which has the advantages of light weight, high strength, anti-corrosion, heat preservation, insulation, and sound insulation. The reinforcing material of FRP acts as a skeleton, and its composition is fiber materials such as glass fiber, carbon fiber, boron fiber, aramid fiber, alumina fiber and silicon carbide fiber; the matrix material of FRP plays a bonding role, and its composition is ring Oxygen resin, unsaturated polyester resin, phenolic resin and other synthetic resins. Traditional FRP products are made by hand lay-up. In this method, a mold corresponding to the shape of the product is first prepared, a layer of release age...
