Abstract

The invention provides a one-step composite molding preparation method combining a pultrusion molding method and a winding molding method, and a composite hollow profile can be prepared. Reinforced fibers in the tube wall of the composite hollow profile are divided into an inner layer and an outer layer. The direction of the reinforced fibers in the inner layer is consistent with the pulling direction, and the reinforced fibers in the inner layer mainly bear pulling force in the preparation process and pulling force in the length direction of the composite hollow profile in the using process. The reinforced fibers in the outer layer are wound outside the reinforced fibers in the inner layer, an included angle which is proximately 90 degrees is formed between the reinforced fibers in the outer layer and the reinforced fibers in the inner layer, and the reinforced fibers in the outer layer mainly bear expansion pressure from the interior of the hollow profile. Due to the fact that all resin in the inner layer and the outer layer is subjected to one-time curing molding, the overall strength is obviously improved, the production flow is simplified, the production cycle for the composite hollow profile can be shortened, occupation of production sites is reduced, labor is relieved, and the production cost can be lowered.

Description

Pultrusion is wound around composite molding and prepares composite material hollow section bar
Technical field
Pultrusion winding composite molding is prepared composite material hollow section bar and is belonged to a kind of composite material and preparation method thereof.
Background technology
Conventional composite material and preparation method thereof has multiple, including pultrusion heating cure method with Wrapping formed heat Solidification method.
Pultrusion heating cure method has that continuous production is good, automaticity is high and low cost and other advantages, but exists Reinforcing fiber trend is single feature alongst, and the composite material hollow section bar that pultrusion processes produces exists anti- The shortcomings such as internal pressure capability is poor, twisting resistance is poor and easy to crack.
Wrapping formed heating cure method have anti-internal pressure capability by force, the most easy to crack, designability good and technique is more flexible etc. Advantage, but have that continuous production is poor, automaticity is the highest and the shortcoming such as relatively costly.
In order to overcome the shortcoming of composite material hollow section bar prepared by aforementioned two kinds of methods, existing method is two-step method, That is: the first step, utilizes pultrusion heating cure method to prepare composite material hollow section bar；Second step, prepared by the first step Composite material hollow section bar is mandrel, in its outer felt around one layer of reinforcing fiber prepreg tape, the most heated curing molding, prepares Two-layer reinforcing fiber trend is bordering on vertical composite material hollow section bar.
, there is process complexity, production cycle length and production cost relatively in the two-step preparation of existing composite material hollow section bar High shortcoming, and owing to internal layer and the Wrapping formed outer layer of pultrusion are to solidify to form respectively through twice, internal layer with Resin bonding strength between outer layer is the highest, directly affects the overall performance of composite material hollow section bar.
Summary of the invention
Present invention aim at providing a kind of composite material hollow type having pultrusion processes and filament winding process advantage concurrently Material preparation method.
The composite one-step shaping preparation side that the present invention is a kind of pultrusion processes and filament winding process combines Method, it is possible to preparing a kind of composite material hollow section bar, the reinforcing fiber in its tube wall is divided into internal layer and outer layer.
Internal layer reinforcing fiber trend is consistent with pull direction, and drawing gravitation when mainly undertaking preparation is subject to during using The tension along composite material section bar length direction.
Outer layer reinforcing fiber is wound in outside inner fiber, with inner fiber in the angle of about 90 °, mainly undertakes and comes from The bulbs of pressure within hollow profile.
Resin is filled in the internal all gap with reinforcing fiber interlayer of reinforcing fiber layer, and after hardening by all enhancings Consolidated fibers is integrated, and forms composite material hollow section bar.
Composite material hollow section bar prepared by this one-step shaping method, with the composite material hollow prepared by two one-step forming methods Section bar compares, owing to internal layer and all resins of outer layer significantly improve through one-step solidification moulding, bulk strength.
Owing to simplifying production procedure, it is possible to shorten the production cycle of composite material hollow section bar, reduce production site Take and liberate manpower, it is possible to reducing production cost.
Optimize, owing to all there being heating element heater inside core and cover die, it is possible to significantly improve composite wood in production process The solidification programming rate of material hollow profile, so that pultrusion, speed of wrap quickening, improves production efficiency.
Optimizing, the heating power of the heating element heater within core and cover die matches with pull speed, it is possible to ensure Solidification temperature needed for composite material hollow section bar.
More optimal, by means of the effect of tying tight in outer layer reinforcing fiber winding process, be finally prepared to is compound In material hollow profile, the accounting of reinforcing fiber is high, further increases the overall performance of composite material hollow section bar.
Accompanying drawing explanation
Fig. 1 is the method implementation process schematic diagram of the present invention.
In accompanying drawing 1,1 is supplied with reinforcing fiber bundles, and 2 is resin liquid bath, and 3 is resin liquid, and 4 is prepreg tape, and 5 is plastic squeeze plate, and 6 Being wound around reinforcing fiber tow, 7 is that 8 is core, and 9 is wire winding device for fiber tube, and 10 are wound around reinforcing fiber for wire spool, 11 Being core heater, 12 is the cover die of band heating function, and 13 is cured composite material hollow section bar, and 14 is pulling device, 15 It it is drawing gravitation direction.
Under pulling device 14 acts on, supply reinforcing fiber bundles 1 is imported in resin liquid bath 2 and is infiltrated shape by resin liquid 3 Becoming prepreg tape 4, the hole on plastic squeeze plate 5 imports around core 8.
Now, under the effect of wire winding device 9, fiber-reinforced wrapped process for the reinforcing fiber tow in wire spool 10 supplies The endoporus of fiber tube 7 is confessed, and becomes fiber-reinforced wrapped tow 6.
Fiber-reinforced wrapped tow 6 is continuously wrapped in the outside of prepreg tape 4 and forms composite prepreg, and at pull To drawing gravitation direction 15 feeding under device 14 effect.
At this moment, one of favourable effect is the state forming tight bundle between prepreg tape 4 and fiber-reinforced wrapped tow 6.
Another favourable effect is under power of tying tight the effect that fiber-reinforced wrapped tow 6 provides, and prepreg tape 4 leaches Residual resin liquid has been sufficiently wet fiber-reinforced wrapped tow 6.
Subsequently, composite prepreg is imported into the active region of core heater 11 and starts to warm up, and proceeds immediately to core 8 with outer Shaping area between mould 12, reaches final solidification temperature and cross sectional shape in this region, solidify to form composite material hollow Section bar 13.
