specific Embodiment approach 1

[0013] Embodiment 1: The steps of the molding method of the fiber-reinforced resin-based composite material shading cover with inner grid described in this embodiment are as follows:

[0014] Step 1: Mold processing: process the outer surface of the mold with a release agent, and the release agent is selected from high temperature resistant epoxy resin;

[0015] Step 2: forming the inner layer: evenly lay the first layer of fiber cloth on the outer surface of the mold, and then evenly lay the second layer of fiber cloth on the first layer of fiber cloth until the thickness of the laid fiber cloth reaches 0.15 ~ 1mm;

[0016] Step 3: Forming the inner grid: using the wet winding process, using one or more fibers on the upper surface of the inner layer to form the inner grid on the winding machine, the thickness of the inner grid is 0.5-8 mm;

[0017] Step 4: Forming the skin: use wet winding process, dry process or a combination process of wet winding process and dry process t...

specific Embodiment approach 2

[0021] Embodiment 2: This embodiment differs from Embodiment 1 in that the inner grid in step 3 is made of one of glass fiber, carbon fiber, and aramid fiber or a combination of the above three fibers. Others are the same as in the first embodiment.

Abstract

The invention relates to a molding method of a fiber-reinforced resin-based composite material shading cover with an inner grid, which relates to a molding method of the shading cover. The present invention solves the problem that there is no method for integrally forming a fiber-reinforced resin-based composite sunshade with an inner grid at present. Step 1: Treat the outer surface of the mold with a release agent; Step 2: Spread fiber cloth evenly on the outer surface of the mold until the thickness of the laid fiber cloth reaches 0.15-1mm; Step 3: Use wet or dry winding process, using one or more fibers to form the inner grid on the winding machine; step 4: using wet winding process, dry process or a combination of wet winding and dry process to form a skin on the outer surface of the inner grid; Step five: product curing; step six: processing the outer surface; step seven: demoulding and trimming. The fiber-reinforced resin-based composite material shading cover formed by the method of the invention has the advantages of high precision, high production efficiency and low cost.

Description

technical field [0001] The invention relates to a forming method of a composite material shading cover with an inner grid. Background technique [0002] The fiber-reinforced resin-based composite material hood with inner grid is used for the hood on the telescope. The structure and function of the hood are divided into three parts: the inner layer, the inner grid and the skin, and each part has its special requirements. The inner layer is required to have the function of anti-wear and anti-cracking, so its use requirements must be considered in material selection and molding process. The inner grid requires high dimensional accuracy and structural rigidity. For the inner grid of resin-based composite materials, it is necessary to combine the special structural characteristics of the grid with the composite material molding technology, regardless of the material or the molding process. There are no relevant data reports and practical applications at home and abroad, so a se...
