Abstract
The invention provides a novel fiber reinforced cellular board and a preparation method thereof. The novel fiber reinforced cellular board consists of panels on the two sides and a cellular core of a pyramid-shaped structure. The cellular core of the pyramid-shaped structure is prepared by the following steps: injecting high-strength dispersed short-cut fiber cotton/felt into an epoxy resin substrate; or presoaking the epoxy resin substrate by the high-strength dispersed short-cut fiber of 10 mm to 30 mm to form a pre-mixed molding material; and heating, pressurizing and molding the pre-mixed molding material. The prepared cellular core consists of a series of concave-convex staggered pyramid-shaped platform bodies which form a stable whole body together under the action of the two panels on the two sides, so the novel fiber reinforced cellular board has various high mechanical properties. The novel fiber reinforced cellular board has very simple molding process and low production cost, and can realize continuous high-efficiency production.
Description
Technical field
The present invention relates to a kind of composite, be specially a kind of fibers honeycomb composite plate and preparation method thereof.
Background technology
The fiber reinforcement cellular composite material is because it is in light weight, intensity is high, rigidity is big, designability can reach advantages such as corrosion-resistant well, is bringing into play important effect at Aeronautics and Astronautics, boats and ships, automobile and other field widely, is subjected to liking of numerous users deeply.But existing fiber reinforcement cellular composite material is subjected to the legacy cellular cored structure and the influence of difficulty that is shaped, and adopts on aluminium honeycomb core, plastic honeycomb core, the paper honeycomb core bondable fibers to strengthen foreign material such as panel mostly and makes.Though it all is the cellular board of fibre reinforced materials that a small amount of honeycomb core and panel are also arranged, the shaping of honeycomb core and manufacture craft are very complicated, cost is high, efficient is low and the cellular board product defects of production is many.More than these situations directly influenced the mechanical property such as rigidity, intensity, anti-fissility of fiber reinforcement honeycomb composite plate and production cost, production efficiency and range of application.
Summary of the invention
Purpose of the present invention is exactly for addressing the above problem, provide a kind of structure more rationally, mechanical property is better, be convenient to be shaped, make simple fiber reinforcement cellular board.
Scheme of the present invention is: novel fiber reinforced cellular board is made of both sides panel and fiber reinforcement pyramid honeycomb core, the pyramid honeycomb core is with shape high strength chopped strand silk/felt at random, form through pressure injection resin colloid or with chopped strand premix mould process, made honeycomb core is made up of a series of concavo-convex staggered pyramid stage bodies, the oblique facade of little pyramid is the ribs limit, and the pyramid point is a facet, and oblique so upright rib limit and facet constitute the interdependent each other concavo-convex pyramid body structure of monoblock type.Fiber reinforcement pyramid honeycomb core can be polygonal pyramid stage body structures such as triangular pyramid stage body or rectangular pyramid stage body, and the lower plane of its upper surface and top panel is affixed, and the last plane of lower surface and lower panel is affixed.
The manufacture method and the step of novel fiber reinforced cellular board of the present invention are as follows:
Step 1: the mould of making tencel enhancing pyramid honeycomb core is made up of bolster, be processed with little pyramid boss body above the template, its size is made by the requirement of required processing cellular board, each boss height low tone is every unanimity, proper alignment, bolster matched moulds rear boss is interlaced arrangement and leaves equal gap, and coats releasing agent.
Step 2: (1) method one: laying high-strength fortifying fibre cotton/felt at random on lower bolster, with upper and lower template assembling matched moulds, and with mold cramping.Inject epoxy resin-base in injecting hole, injection pressure scope 0.4-0.5MPa makes the complete impregnated with resin matrix of dried fiber.(2) method two: evenly lay enhanced short fiber premix on lower bolster, with upper and lower template assembling matched moulds.
Step 3: finish or the bolster of the good premix of lay, moulding material is put into the hot press cure under pressure of heating pressure injection is molded, solidification temperature is 150-180 ℃, solidifying pressure is 2-6MPa, keeps the demoulding after 2.5-3.5 hour, promptly makes fortifying fibre pyramid honeycomb core.
Step 4: multi-layer fiber cloth/silk or prepreg are laid on the flat board, and coated with resins base colloid successively, repeating step three promptly makes prefabricated fortifying fibre panel then
Step 5: roll resin adhesive with being coated with on the small end face about the fiber reinforcement pyramid honeycomb core for preparing, the panel and the glue-coated honeycomb core that prepare are combined again, repeating step three promptly makes tencel and strengthens the pyramid cellular board.
Because it is pyramid honeycomb core of the present invention is to adopt high-strength chopped strand resin pickup matrix to be molded as frustum of a pyramid shape, and is in light weight, more firm stable, not yielding on the structure.Especially connect each other at the recessed convex cone platform of the effect of fiber reinforced panel, interact, support mutually, constituted a firm integral body jointly, have good resistance to compression, anti-bending mechanics performance, all have very big advantage at aspects such as opposing impact, energy absorption and dissipation.And the bonding of honeycomb core and panel is that the larger area face is affixed, and non-traditional consolidation style, its anti-fissility, rigidity, intensity have all had very big lifting, are a kind of new structure fiber reinforcement cellular boards of mechanical property excellence.From manufacturing cone table stereochemical structure that honeycomb core is made up of oblique facade and making shape, can not cause damage to fiber by short fiber resin pickup rubber moulding.The stage body shaping form is a pyramid simultaneously, and forming technology is simple easily, materials are economized, cost is low, be not prone to product defects.Simultaneously, Mold Making is also very simple, the also easily demoulding in the coremaking process, but continuous high-efficient production.
