Description
Technical Field
The invention relates to the technical field of composite materials, in particular to a composite material hand lay-up forming anti-drop tool and a use method thereof.
Background
Since the advent of composite materials, the excellent properties of the composite materials are favored by various industries, and the composite materials are widely applied to the fields of national defense and military, aerospace, information technology, energy engineering, ship engineering, ocean engineering and the like. Compared with the traditional materials, the composite material has the advantages of light weight, high specific strength, high specific rigidity, good corrosion resistance, fatigue resistance, layering designability and the like.
The hand lay-up process is also called a low-pressure contact forming process, is a forming process with low cost and low equipment requirement, has wide adaptability, is reserved and widely applied due to the characteristics even though high-performance forming process modes such as vacuum introduction, RTM, winding and the like exist at present, is inconvenient to use and can only be used for forming composite materials in special environments. Therefore, when the hand lay-up process is used in a specific environment, how to improve the molding quality of the hand lay-up process is critical.
Patent CN 107225775A discloses a hand lay-up process and a device for the same, which uses a method of pressing a hand lay-up bag into secondary vacuum, coating the upper part of a hand lay-up fiber fabric layer by using a vacuum bag, placing auxiliary materials inside the vacuum bag for absorbing bubbles and residual glue, called a first vacuum, and connecting the first vacuum with a vacuum pump by using a vacuum pipeline. After the first vacuum is sealed with tape, a vacuum bag, called a second vacuum, is wrapped again on the outside of the first vacuum, and a vacuum pipeline is also used to connect the first vacuum with a vacuum pump. After the vacuum valve is started and the first vacuum is started, redundant bubbles and glue solution in the hand-lay-up fiber fabric can be extracted, and the bubbles and the glue solution can be adsorbed in the glue absorbing felt or discharged through a vacuum pipeline. After the first vacuum is stable, the second vacuum is started, the second vacuum bag is contracted, and the first vacuum is shaped and pressurized slightly.
The prior art has two main problems, namely, the first hand pasting bag pressing forming process requires that the lower part of the hand pasting fiber fabric is in a sealed state, if unsealed condition exists, an air flow channel is formed between a bottom air leakage part and a vacuum pipeline when first vacuum is applied, and under the action of atmospheric pressure, air bubbles are sucked into the composite material from the bottom air leakage part and move to negative pressure at the vacuum pipeline, so that the appearance of the composite material is whitened, and the appearance of the composite material is actually caused by a large number of small air bubbles in the composite material. Secondly, in the construction state of construction on the vertical surface or above the top, the hand lay-up shaped fiber fabric cannot be effectively stuck on the surface of the construction position for a long time, and is likely to slide off before the vacuum bag is covered. Therefore, there is a need for improved optimization technically.
Therefore, the invention provides an anti-drop tool for molding the composite material by hand paste and a use method thereof.
