Embodiment Construction

[0028] see figure 1 and figure 2 , The present invention relates to a glass fiber reinforced polyurethane / paper honeycomb sandwich composite car sleeper board, comprising a sleeper frame 1, the sleeper frame 1 is an iron frame, which is composed of C-shaped steel plates and L-shaped steel plates spliced ​​together. The C-shaped steel plate is embedded with bamboo slats 2 to improve the strength of the sleeper frame 1, and the sleeper frame 1 is embedded with honeycomb paper 3, and the outer layer of the sleeper frame 1 is provided with a mixed layer of PU and glass fiber, so as to The role of curing sleeper boards.

[0029] The preparation process of this glass fiber reinforced polyurethane / paper honeycomb sandwich composite car sleeper board is as follows:

[0030] 1. Stretch forming: Use a honeycomb paper stretching machine, set the temperature at 120°C, stretch the honeycomb paper to a size of 2100mm*680mm, and the honeycomb holes are regular hexagons.

[0031] 2. Cutti...

Abstract

The invention relates to a glass fiber reinforced polyurethane / paper honeycomb sandwich composite sleeper plate for a vehicle. The glass fiber reinforced polyurethane / paper honeycomb sandwich composite sleeper plate for the vehicle is characterized in that the sleeper plate comprises a sleeper framework (1), the sleeper framework (1) is an iron frame, honeycomb paper (3) is embedded into the sleeper framework (1), and a PU and glass fiber mixing layer (4) is arranged on the outer layer of the sleeper framework (1). The glass fiber reinforced polyurethane / paper honeycomb sandwich composite sleeper plate for the vehicle is light in weight, has a vibration resistance function, a thermal insulation function and the like, and is little in material consumption, high in strength, not prone to deformation and warping, moderate in price and cost, degradable and recyclable, and compared with a sleeper plate with a traditional structure, the sleeper plate has the advantages that the weight can be reduced by more than 30%.

Description

technical field [0001] The invention relates to a glass fiber-reinforced polyurethane / paper honeycomb sandwich composite car sleeper board and a preparation process for the sleeper board, belonging to the technical field of automobile decorations. Background technique [0002] In order to meet the needs of commercial vehicle users to rest during long-distance transportation, sleepers are usually installed in the cockpit of commercial vehicles for people to use. According to the configuration of the cab, there are two types of sleeping berths: single berth and double berth. Due to the higher load-bearing and safety requirements, the double-bed upper sleeper generally adopts a steel-wood frame structure; the lower sleeper usually adopts a simple steel-wood structure or a non-metallic sleeper board because of the support of the ground seat. [0003] In my country, the development and application of automotive interior sleeper boards lag behind. At first, sleeper boards assembl...
