The technical scheme for realizing the purpose of the utility model is that the carbon fiber felt composite glass fiber knitted felt prepreg comprises a composite felt layer impregnated with resin paste and PP thin film layers on two sides of the composite felt layer, wherein the composite felt layer and the PP thin film layers on two sides are respectively bonded and fixed through resin paste layers; the composite felt layer is obtained by compounding a glass fiber knitted felt and a carbon fiber felt.
Optionally, the composite felt layer is of a three-layer structure and consists of a glass fiber knitted felt and carbon fiber felts on two sides of the glass fiber knitted felt; or consists of a carbon fiber felt and glass fiber knitted felts on both sides of the carbon fiber felt.
Optionally, the composite felt layer is composed of a glass fiber knitted felt layer and a carbon fiber felt layer.
The thickness of the resin paste layer is 0.3mm to 1 mm.
The thickness of the PP film layer is 0.03 mm-0.05 mm.
The PP film layer is a black PP film layer.
The utility model discloses has positive effect:
(1) the utility model discloses a compound fine knitting felt preimpregnation material of carbon fiber felt compound glass glues the compound felt that glues with including middle impregnating resin and the PP film of its both sides, is pasted by the resin between PP film and the compound felt and is connected.
In the conventional prepreg, a PE film is used as release paper, and a PP film is not suitable for being used as a separation film, so that the use of a PP film layer as a separation protective layer is never proposed. The utility model discloses a fine knitting felt preimpregnation material of compound glass of carbon fiber felt adopts the PP thin layer as the isolation protective layer, compares in the PE thin film that tradition used, has tensile strength height, difficult fracture, can effectively prevent the volatile advantage of styrene, and the retention period is longer, and product quality is stable.
(2) For some light-cured resin pastes, to ensure the stability of the prepreg, black PP films were used to coat both sides of the resin paste impregnated composite mat.
(3) The prepreg of the carbon fiber felt composite glass fiber knitted felt can be used for producing products in die pressing, pipe coiling or laminating processes after being cut, an upper layer film and a lower layer film are removed during use, the products are placed into a die for high-temperature forming after being cut randomly, the wet operation is changed into the dry operation, the operation environment of workers can be effectively improved, and the volatilization of harmful substances in the operation environment is reduced; the method can be used in the fields of pipeline repair, container reinforcement, electrostatic dust removal equipment lining and the like.
Drawings
Fig. 1 is a schematic structural view of the carbon fiber felt composite glass fiber knitted felt prepreg of the present invention;
the reference numbers in the above figures are as follows: the composite felt layer comprises a composite felt layer 1, a resin paste layer 2 and a PP film layer 3.
Detailed Description
(example 1)
Referring to fig. 1, the prepreg of the carbon fiber felt and glass fiber composite knitted felt (hereinafter referred to as composite felt) of the embodiment is of a sandwich structure and comprises a composite felt layer 1 impregnated with resin paste and PP thin film layers 3 on two sides of the composite felt layer 1, and the composite felt layer 1 and the PP thin film layers 3 on two sides are bonded and fixed through a resin paste layer 2 respectively.
The composite felt layer 1 in this embodiment is a composite felt impregnated with an unsaturated polyester resin paste. The composite felt layer 1 is obtained by compounding a glass fiber knitted felt and a carbon fiber felt. In this embodiment, the composite felt layer 1 has a three-layer structure, and is composed of a glass fiber knitted felt and carbon fiber felts on both sides thereof. In addition to the above structure, the composite felt layer 1 may also be composed of a carbon fiber felt and glass fiber knitted felts on both sides thereof according to actual requirements; or only consists of a layer of glass fiber knitting felt and a layer of carbon fiber felt.
The glass fiber knitted felt is formed by cutting glass fiber direct yarns into certain lengths, arranging the glass fiber direct yarns in disorder, and then stitching and knitting the glass fiber direct yarns by using polyester stitching yarns.
The thickness of the resin paste layer 2 is 0.3mm to 1mm, and in this example, 0.5 mm.
The thickness of the PP film layer 3 is 0.03mm to 0.05mm, and in this embodiment, 0.03 mm.
The PP film layer 3 is a transparent or colored PP film layer 3, and for some photo-cured resin pastes, in order to ensure the stability of the prepreg, the two sides of the glass fiber checked cloth impregnated with the resin paste are coated with black PP films.
The preparation process of the carbon fiber felt and glass fiber composite knitted felt prepreg comprises the following steps:
pouring the prepared resin paste (the unsaturated polyester resin mixture added with the functional filler, the curing agent, the internal release agent, the thickening agent and the low-shrinkage additive) into an upper glue groove and a lower glue groove of a glue dipping machine, coating the resin paste on the inner surfaces of an upper PP film layer and a lower PP film layer, dipping the carbon fiber felt composite glass fiber knitted felt (composite felt) into the resin paste through the lower glue groove, clamping the resin paste between the upper film layer and the lower film layer coated with the resin paste, rolling the resin paste, then placing the resin paste into a drying room for thickening, and obtaining a finished product after thickening.
The utility model discloses a compound felt preimpregnation material can be cut out the back and be arranged in mould pressing, reelpipe or lamination technology to produce goods, takes off two-layer film about during the use, puts into the mould after tailorring wantonly and carries out high temperature molding or photocuring shaping, can be used for fields such as pipeline restoration, container reinforcement, electrostatic precipitator equipment.
Compare in the PE film of traditional use, the utility model discloses an adopt in the preimpregnation material structure be the PP thin layer, have tensile strength height, difficult fracture, can effectively prevent the volatile advantage of styrene, preimpregnation material storage life is longer, product quality is stable.
