Abstract

The invention discloses a novel snowboard which is composed of a composite material inner core, a bottom plate and a surface layer. The inner core is formed by composite of high-molecular-weight foamed polypropylene and graphite fibers, and has the thickness of 5-6 mm; the bottom is made of ABS resin, and has the density of 1.03-1.05 g/cm<3> and the thickness of 1.5-2.5 mm; the surface layer is formed by composite of carbon fibers and ABS resin, and has the thickness of 1.5-2.5 mm. The snowboard inner core prepared from a fiber reinforced polypropylene material has the advantages of light weight, high strength, high impact strength performance, high elasticity and good toughness, thereby reinforcing the damping performance of the snowboard. The bottom plate is made of the high-strength ABS resin and has the advantages of relatively high strength, relatively high impact toughness, good wear resistance, good heat resistance, relatively high chemical stability, relatively high insulating property, easy forming and good machinability. The surface layer is a material formed by composite of the carbon fibers and the ABS resin and has the advantages of good corrosion resistance, good electric insulation, good transparency, and relatively good appearance processing characteristics, can prevent static electricity from being generated in the running process of the snowboard, and has the thickness of 1.5-2.5 mm. The snowboard is prepared by heating and rolling the layers.

Description

The preparation method that expanded polypropylene strengthens skis with graphite fiber composite materials

Technical field

The present invention relates to the manufacture method of a kind of skis, the preparation of its inner core belongs to field of polymer composite material, and final prepared product is skis equipment making field.

Background technology

The material of skis and all more various with material, for many years, reduce the resistance of motion between skis planing surface and snow face, reduce the weight of skis, improve the damping performance of skis, improve endurance and the intensity of skis, and improve the insulating properties of skis, it is prevented that slide electrostatic effect and cause absorption impurity on skis to affect the problems such as speed and paid close attention to by people always.Carbon fiber and composite thereof, because of combination property and the high added value of its excellence, be referred to as " the black gold " of 21st century by people.In actual applications, carbon fiber is commonly used as fortifying fibre, carbon fiber reinforced composite be generally of high intensity, high rigidity and light-weighted characteristic, thus extensively utilized in modern industry.Have become as current composite with carbon fiber for main reinforcing material and strengthen the study hotspot in field.

The technical problem to be solved is in that, utilize skis inner core prepared by high molecular expanded polypropylene and graphite fiber composite materials, due to graphite fibre, to have proportion little, intensity is high, modulus is high, corrosion-resistant premium properties such as grade, is significantly increased to core performance in skis with after expanded polypropylene compound.And due to the electric conductivity that carbon fiber is excellent, it has been internally formed electronic loop at skis, skis is in use consumed owing to shaking the electronic loop formed after produced energy converts electric energy to by resistance in graphite fibre and electric energy, and system shake frequency can reach more than 85%.

Summary of the invention

The research purpose of the present invention is in that to solve the strength problem of skis, solve simultaneously in use because electrostatic effect causes skis absorption impurity thus the problem affecting skis sliding speed.

In order to realize the purpose of foregoing invention, solving skis problem in actual applications, the present invention provides techniques below scheme:

(1) high molecular expanded polypropylene and graphite fiber composite materials being cut into slices, slice thickness is 5 ~ 6mm, and long 150 ~ 155cm, wide 27 ~ 29cm, as the inner sandwich layer material of skis.

(2) using ABS material thin slice as skis primer, its thickness is 1.2 ~ 1.8mm, long 150 ~ 155cm, wide 27 ~ 29cm；

(3) in above-mentioned (2) step, the density of ABS resin is 1.03 ~ 1.05g/cm3；

(4) passing through to heat by skis inner core prepared in above-mentioned (1) and (2) step and primer, extruding, bonding prepares into composite bottom board；

(5) heating composite bottom board prepared in above-mentioned (4) step to 140 ~ 150 DEG C, be positioned in roll squeezer and carry out pressurized treatments, pressurization pressure is 1050Pa, and keeps 15 ~ 25min；

(6) using the surface layer that carbon fiber and ABS resin are composited, its thickness is 1.5 2.5, long 150 ~ 155cm, wide 27 ~ 29cm；

(7) composite bottom board that ski surface layer prepared in above-mentioned steps (6) is prepared with step (5) is carried out compoiste adhering, carry out edge polishing according to required form, prepare finished product skis product.

(8) it is an advantage of the current invention that: skis prepared by the method for the invention, main body uses material to be macromolecular material, lightweight, fine corrosion resistance, prepared skis inner core is composited by high molecular expanded polypropylene and graphite fibre, solving the strength problem of skis, and can reach better damping effect, surface layer adopts carbon fiber and ABS resin to be composited can solve the problem that skis is converted into power consumption by vibration energy.
