Vacuum infusion double-layer fiberglass reinforced plastic with hollow monitoring structure and production process for vacuum infusion double-layer fiberglass reinforced plastic

Abstract

The invention relates to vacuum infusion double-layer fiberglass reinforced plastic with a hollow monitoring structure and a production process for the vacuum infusion double-layer fiberglass reinforced plastic. The vacuum infusion double-layer fiberglass reinforced plastic comprises a sealed cavity formed by upper and lower fiberglass reinforced plastic layers, wherein the hollow monitoring structure is formed in the sealed cavity formed between the upper and lower fiberglass reinforced plastic layers and is an interconnected mesh layer. The vacuum infusion double-layer fiberglass reinforced plastic with the hollow monitoring structure simultaneously has the advantages of high strength, good uniformity, smoothness and density and does not have the defects of bubbles, pin holes and the like. Meanwhile, according to the vacuum infusion double-layer fiberglass reinforced plastic, the environmental protection action and vacuum system curing are realized, and the quantity of volatile matters flowing out in the chemical reaction process is reduced; and as a soluble or fusible middle layer is adopted, and meshes are formed in the middle layer, after being dissolved or fused, the middle layer is formed into a stereo reticular structure, a penetration middle layer is also formed, and meanwhile, the reticular stereo structure has good enhancement action.

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 double-layer glass fiber reinforced plastic with a hollow monitoring structure and a production process thereof. Background technique: [0002] The present invention relates to all FRP double-layer hollow monitoring structures, and in particular to the anti-leakage monitoring structure of underground oil tanks in gas stations. Most of the existing oil tanks buried underground are ordinary steel oil tanks, which lack leakage monitoring technology, such as Leakage cannot be found and resolved immediately, causing great potential safety hazards. At present, the national industry requires mandatory renovation of the original underground oil tanks, which must be able to effectively solve the leakage prevention problem and strictly implement SH / 3177-2015 and SH / 3178 -2015 standards, a large number of oil tanks in China nee...
