Example Embodiment

[0024] Example one:

[0025] See figure 1 with 2 , Provide a vacuum infused multilayer hollow glass fiber reinforced plastic 0 with high barrier properties, including a first glass fiber reinforced plastic layer 11, a second glass fiber reinforced plastic layer 12, a resin-rich layer 4 and a supporting member 2. The first layer of FRP layer 11 and the second layer of FRP layer 12 are FRP layer 1, forming a sealed chamber 3, and the sealed chamber 3 is a hollow structure. The resin-rich layer 4 is attached to one surface of the second FRP layer 12 to form a FRP layer with a resin-rich layer 4. The supporting member 2 is located in the sealed chamber 3 and divides the sealed chamber 3 into a plurality of spaces, and the plurality of spaces are communicated with each other, and the supporting member 2 can improve the strength.

[0026] The mass content of the resin in the resin-rich layer 4 is greater than or equal to 75%, and the mass content of the fiber in the resin-rich layer 4 i...

Example Embodiment

[0045] Embodiment two:

[0046] In order to manufacture reinforcing ribs with higher mechanical strength, on the basis of Example 1, a process step is added between step 4 and step 5: laying a dry fiber layer in the gap between the soluble and fusible intermediate layer, and vacuum During infusion molding, the reinforcing ribs of the pure resin matrix in the first embodiment of the reinforcing ribs are improved to have fiber-reinforced resin reinforcing ribs, which greatly improves the mechanical strength of the first embodiment. figure 1 the same.

Example Embodiment

[0047] Embodiment three:

[0048] In order to further enhance the barrier properties of the high-barrier double-layer hollow glass fiber reinforced plastic, on the basis of the first embodiment, a process step is added between step 3 and step 4: laying the fiber layer of fluffy structure according to product requirements; Both the lower surface of FRP and FRP 22 have a high barrier resin-rich layer, which improves the barrier properties of Example 1 and improves the leakage resistance of the double-layer hollow FRP. For the structural diagram, see image 3 .

Abstract

The invention discloses a vacuum-poured multilayer hollow glass fiber reinforced plastic with a high barrier property. The vacuum-poured multilayer hollow glass fiber reinforced plastic comprises at least two glass fiber reinforced plastic layers, at least one resin rich layer and supporting components. Every two glass fiber reinforced plastic layers form a sealing cavity, and each sealing cavityis of a hollow structure. Each resin rich layer is located on one face of the corresponding glass fiber reinforced plastic layer. The supporting components are located in the corresponding sealing cavity and partition the sealing cavity into a plurality of spaces, and the multiple spaces communicate with one another. The vacuum-poured multilayer hollow glass fiber reinforced plastic with the highbarrier property is produced through a production process. In this way, the vacuum-poured multilayer hollow glass fiber reinforced plastic achieves environmental protection operation and vacuum systemcuring, flowing out of volatile matter in a chemical reaction process is reduced, and contact between construction workers and the volatile matter in the chemical reaction process is avoided; and meanwhile, the vacuum-poured multilayer hollow glass fiber reinforced plastic has the advantages of being high in strength, good in uniformity, smooth, dense, free of bubbles, free of pinholes and the like.

Description

technical field [0001] The invention relates to a hollow glass fiber reinforced plastic and a vacuum filling process thereof, in particular to a vacuum filling multi-layer hollow glass fiber reinforced plastic with high barrier property and a production process thereof. Background technique [0002] Oil tanks are containers for storing crude oil or other petroleum products and can be used in refineries, gas stations, oil fields, oil depots, and other industries. Most of the existing buried underground oil tanks and transport oil tanks are ordinary steel oil tanks, which lack anti-leakage technology and are prone to leaks, causing great potential safety hazards. At present, the national industry requires the mandatory transformation of the original underground oil tanks and related transportation oil tanks, which must be able to effectively solve the leakage prevention problem and strictly implement the standards of SH / 3177-2015 and SH / 3178-2015. [0003] A large number of o...
