Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of composite product structure top layer.
In order to realize above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of composite product structure top layer, comprises the not moulding prefabricated product of composite membrane, carbon fiber; By pasting, film is pasted onto on the upper surface of the not moulding prefabricated product of carbon fiber described composite membrane, the upper surface of described stickup film is provided with glass felt composite membrane, described glass felt composite membrane is provided with glass felt, the upper surface of described glass felt composite membrane is provided with carbon felt composite membrane, described carbon felt composite membrane is provided with carbon felt, the not moulding prefabricated product of described carbon fiber are provided with the fine base material of carbon, are provided with epoxy resin between the fine base material of described carbon, and described epoxy resin connects and composes carbon fiber layer successively.
Further, described carbon felt is the tNonwovens shape thing formed by dryness staple fibre.
Further, described glass felt is the tNonwovens shape thing formed by short glass fiber.
Further, the front of described glass felt composite membrane is the tNonwovens shape thing that dryness short carbon fiber is formed, and reverse side is every square metre of resin molding lower than 20g.
Further, described carbon felt composite membrane front is the tNonwovens shape thing that dryness short glass fiber is formed, and reverse side is every square metre of resin molding lower than 20g.
Adopt after technique scheme, the utility model compared to the prior art advantageously:
Composite product structure top layer described in the utility model, blow and present carrying out closing film in the structure top layer that carbon felt/glass felt/carbon felt composite membrane/glass felt composite membrane is attached to carbon fiber and fiber reinforced composite material goods, close the shaping process of film utilizes characteristic that the adsorptivity of felt is strong by gas producing formation between hole air (bag wind) and pin hole again before resin gel drainage discharge, the fillibility of felt is utilized to repair surperficial poor resin region and resin-rich area disappearance, thus improve working efficiency, reduce Strength Safety hidden danger, bring better life safety assurance to human consumer.
