Embodiment 1

[0024] Such as figure 1 As shown, a lightweight compartment panel includes a gel coat layer 1 , an outer skin layer 2 and an inner core layer 3 . The outer skin layer 2 is installed on both sides of the inner core layer 3 . The gel coat layer 1 is installed on both sides of the outer skin layer 2 . The outer skin layer 2 is made of fiberglass. The inner core layer 3 has a honeycomb structure. The inner core layer is made of PP material. The thickness of the outer skin layer is 1mm. The thickness of the inner core layer is 10mm.

[0025] A method for preparing a lightweight car panel, the steps are as follows:

[0026] S1. Take two flat molds, clean them, and then treat the clean two flat molds with a release material, then spray the gel coat evenly on the flat molds, and finally send the flat molds into the press for heating and curing. The heating and curing time of the flat mold is 30 minutes. Use masking paper to circle the area where the length and width of the pre...

Abstract

The invention discloses a lightweight carriage plate and a preparation method thereof. The lightweight carriage plate comprises gel coat layers, outer skin layers and an inner core layer. The outer skin layers are mounted on the two sides of the inner core layer; the gel coat layers are installed on the two sides of the outer skin layer. The outer skin layer is made of a glass fiber reinforced plastic material; the inner core layer is of a honeycomb plate body structure; all the layers are pressed and cured through a pressing machine. The lightweight carriage plate is light in weight, and thepreparation method is simple.

Description

technical field [0001] The invention relates to a lightweight carriage board and a preparation method thereof. Background technique [0002] A van is a type of compartment with an independent closed structure, or an integral closed structure compartment integrated with the driver's cab, which is mainly used for fully sealed transportation of various items. The compartment board of the van can be made of iron corrugated, color steel plate, aluminum flat plate, aluminum alloy corrugated or foamed insulation compartment material. [0003] Compared with the car body with metal skeleton structure, the glass fiber reinforced composite material car plate has the advantages of good manufacturability, low cost and light weight of the whole vehicle because it has no skeleton and no pre-embedding in the process of manufacturing. Through various comparisons, the compartment panels made of glass fiber reinforced composite materials and lightweight sandwich materials are not only in line...
