Abstract
The invention provides a novel device and technology for manufacturing an ultra-thick composite plate by means of vacuum infusion, and aims at solving the problem that the ultra-thick composite plate is hard to manufacture by means of vacuum infusion. The thickness of the composite plate is larger than 8 mm. According to the scheme, a layer of flow guide medium is laid on the upper surface of a pre-forming body, and a layer of flow guide medium is laid on the lower surface of the pre-forming body; after resin is poured, the resin on the upper surface of the pre-forming body downwards permeates into fibers through gravity and surface acting force, and the resin on the lower surface of the pre-forming body upwards permeates into the fibers through surface acting force; and the distance of a resin infiltration reinforcement body is shortened, the resin pouring time is shortened, the defects of the composite plate are reduced, and the success rate of the composite plate is increased. The technical problem that the ultra-thick composite plate or product is hard to manufacture by means of a vacuum infusion method is solved, the application range of the vacuum infusion method is widened, and meanwhile a thought is provided for low-cost manufacturing of the ultra-thick composite plate or product.
Description
Technical field
The present invention relates to a kind of vacuum introductory technique and prepare super thick composite board device and technique thereof.
Background technology
Many excellent characteristics such as fibre reinforced composites are a kind of novel high performance materials, have specific strength high, and specific modulus is large, corrosion-resistant, are used to Aero-Space, track traffic, automobile, in the various fields such as Leisure Sport.The moulding process of current composite mainly comprises autoclave forming process, pultrusion molding process, winding shaping process, resin transfer molding, many moulding process such as vacuum importing, wherein vacuum guiding and forming technique is that a kind of cost is low, operates easy liquid molding process, in the manufacture of composite product, have larger advantage.But because of the limitation of its process characteristic, for thicker, the more difficult realization of more complicated composite product, also limit its extensive use.
The principle of vacuum guiding and forming technique is at one atm, is filled into by resin in reinforcement, and by the flowing of resin, infiltration, infiltrates reinforcement fiber gradually.Resin wetting fibre mainly contains two active forces, and the first, the gravity of resin makes resin permeate below preform gradually, reaches the object of wetting fibre; The second, the interaction force between resin and fiber, makes resin and fiber reach infiltration.In the process that resin and fiber infiltrate, As time goes on, the resistance that resin advances becomes large gradually, and the difficulty of resin wetting fibre is increased, and therefore comparatively large for thickness, the composite product that shape is more complicated, vacuum imports more difficult realization.
Above-mentioned Problems existing, prepares in composite product in vacuum importing and should give enough attention, and should solve actual technical barrier.
Summary of the invention
A kind of vacuum introductory technique provided by the invention prepares super thick composite board device and technique thereof, for solving the more difficult technical barrier realizing super thick composite board product of vacuum introductory technique, expand the range of application of vacuum introductory technique, reduce the cost that super thick composite board manufactures.
