The honeycomb stopper is seared. The invention has features of low cost, convenience of processing and operating, light weight.
Description
Technical field
The invention belongs to the composite material forming technology, relate to improvement the block that is used for the honeycomb sandwich composite moulding.
Background technology
Composite mainly adopts the moulding of the vacuum bag method of forming.When formed honeycomb sandwich part, because vacuumizing pressurization (or pressurized with compressed air) honeycomb generally shrinks, particularly in the marginal portion of product, the edge of honeycomb core often is an angular shape, it is very serious that sharp corner shrinks situation, causes the part quality difference produced even unqualified.Be head it off, domestic main employing at present has the metal backup of same profile and thickness in the profile increase of mould upper edge product, makes the edge wedge angle of honeycomb core not be subjected to lateral pressure, solves the problem that the sharp corner honeycomb shrinks.Its shortcoming is: metal backup processing cost height; Curvature block processing big and thin thickness is very difficult; Metal backup is very heavy, is not easy to operation.
Summary of the invention
The objective of the invention is: propose a kind of cost low, be convenient to process, in light weight, the honeycomb block and the manufacture method thereof that are used for the honeycomb sandwich composite moulding being convenient to operate.
Technical scheme of the present invention is: the honeycomb block that is used for composite material forming, it is characterized in that, it is made up of at 2～4 layers of glass fabric honeycomb core surface, that solidify or carbon cloth honeycomb core and paving, in the hole of honeycomb core, be full of by the bonding glass microsphere of epoxide-resin glue, having a side on the honeycomb block at least is the work profile, this work profile is with identical by the corresponding side view of the honeycomb sandwich composite product of moulding, and the thickness of honeycomb block is with identical by the honeycomb sandwich composite product of moulding.
The manufacture method of the honeycomb block that is used for composite material forming as described above is characterized in that the step of manufacturing is as follows:
1, cutting honeycomb core body stock; According to by the flat shape of the honeycomb sandwich composite product of moulding, with the comb core material identical by the honeycomb sandwich composite product thickness of moulding on cut out the honeycomb core body stock of honeycomb block; When the honeycomb block was positioned at by the outside of the honeycomb sandwich composite product of moulding, the overall size of honeycomb core body stock was than outwards being expanded 30～50mm by the honeycomb sandwich composite product of moulding; When the honeycomb block was positioned at by the internal cavities of the honeycomb sandwich composite product of moulding, the overall size of honeycomb core body stock was identical with the overall size of this cavity;
2, filling glass microballoon;
2.1, gluing; To glass microsphere surface-coated epoxide-resin glue, the heat resisting temperature of this epoxide-resin glue is not less than by the solidification temperature of the employed resin glue of honeycomb sandwich composite product of moulding;
2.2, fill; The glass microsphere that applies epoxide-resin glue is filled in the hole of honeycomb core body stock;
2.3, solidify honeycomb core body stock; The honeycomb core body stock of filling glass microballoon is solidified in heating furnace;
3, honeycomb core body stock is repaiied type; With the finishing of polishing of the work profile of honeycomb core body stock, make it identical with corresponding side view on the master body of product; Other surface finish of honeycomb core body stock are smooth;
4, paving glass fabric or carbon cloth, at honeycomb core body stock surface 2～4 layers of glass fabric of paving or carbon cloth prepreg, identical with by the honeycomb sandwich composite product of moulding of the glass fabric of institute's paving or the resin glue of carbon cloth;
5, solidify the honeycomb block; The honeycomb core body stock of paving glass fabric or carbon cloth is made vacuum bag, put into solidification of hot-press tank after vacuumizing, become the honeycomb block;
6, the honeycomb block is repaiied type; The glue knurl or the burr polishing of honeycomb stop-surface is clean.
Advantage of the present invention is: cost is low, is convenient to processing, and is in light weight, is convenient to operation.Because honeycomb core used in the present invention and glass fabric or carbon cloth all utilize leftover pieces to make, and almost do not have material cost.Compare with metal backup, cost descends more than 60%.Weight only is below 30% of metal backup.
