Problems solved by technology

When the press table squeezes the material in the mold, the uncured epoxy resin glue inside the ski will be squeezed out by the press table, resulting in the low specific gravity of epoxy resin during the mixing process of epoxy resin and glass fiber, which cannot be used Fully mixed glass fiber and epoxy resin
As a result, the mechanical properties of the skis deteriorate, the toughness becomes lower, and brittle fractures are prone to occur

Embodiment Construction

[0028] A method of manufacturing a snowboard, such as figure 1 As shown, the steps include:

[0029] Step 1: Grinding the board, grinding the base plate, core, and panel to the specified thickness according to the drawing, and then engraving and profiling the base plate, core, and panel according to the size of the drawing; making the bonding surface treatment of the base plate, core, and panel more perfect Smooth, easy for subsequent fitting and bonding;

[0030] Step 2: Prepare materials, prepare glass fiber and epoxy resin. The glass fiber is prepared with two axes and the weight is not less than 600g / square meter; the glass fiber is cut according to the size of the core, and the cut The glass fiber is weighed, and the proportion of epoxy resin is weighed according to the ratio of epoxy resin: glass fiber = 13:7, and then the epoxy resin is evenly brushed on the glass fiber cloth, because the glass fiber and the ring Oxygen resin together constitutes the upper glass fibe...

Abstract

The invention discloses a manufacturing method of a snowboard. The snowboard sequentially comprises a bottom board, a lower glass fiber board, a board core, an upper glass fiber board and a panel frombottom to top. The production method comprises the following steps: 1, grinding the bottom plate, the plate core and the face plate to the specified thickness and width according to the drawing size;2, preparing glass fibers and epoxy resin, then weighing the epoxy resin and the glass fibers, and keeping the weight ratio of the epoxy resin to the glass fibers at 13: 7; 3, flatly laying the glassfiber cloth on a workbench, uniformly brushing epoxy resin on the glass fiber cloth, putting the glass fiber cloth into a hot press for curing after uniformly smearing, and extruding 20wt% of epoxy resin in the extrusion process; and 4, evenly smearing epoxy resin glue between all layers of materials of the snowboard, placingthe snowboard into a hot press to be extruded after being evenly smeared, and fixing and forming the snowboard along with curing of the epoxy resin. The snowboard has the advantage that the mechanical property of the snowboard is enhanced.

Description

technical field [0001] The invention relates to the field of ski equipment, in particular to a method for manufacturing a ski. Background technique [0002] Snowboards were invented in Northern Europe in the early 20th century to increase the speed of skiers while skiing. The Ewenki people often use skis as a means of transportation in their usual hunting. Due to the continuous advancement of technology, skis have been differentiated into many different types. Snowboards are generally divided into alpine boards, cross-country biathlon boards, platform boards, freestyle boards, and single boards. The alpine board is composed of a multi-layer structure, mainly including elastic anti-material, box-shaped structure, board core, glass fiber composite material, polymer material bottom plate, metal edge and so on. [0003] An existing snowboard comprises a base plate, a lower glass fiber board, a board core, an upper glass fiber board, and a face plate which are sequentially arra...
