Embodiment Construction

[0024] Such as figure 1 , figure 2 As shown, a continuous fiber thermoplastic composite plastic seat frame, the seat frame is composed of a door-shaped channel frame and a support groove in the door-shaped channel frame, and the door-shaped channel frame and the support grooves in the door-shaped channel frame are connected to each other to form Grooves 11 that communicate with each other as a whole. Such as image 3 As shown, support ribs 31 are provided in the interconnected grooves as a whole; Figure 4 As shown, the inner surface 41 of the integrally interconnected grooves is made of long-fiber thermoplastic composite plastic, the supporting rib is made of long-fiber thermoplastic composite plastic, and the material of the seat frame is continuous fiber thermoplastic composite plastic. Long fiber reinforced thermoplastics are obtained by impregnating long fibers with special resins, and then cut into required lengths, generally 20-30cm; continuous fiber reinforced ther...

Abstract

The invention discloses a continuous fiber thermoplastic composite plastic seat framework and a preparation method thereof. The seat framework is composed of a door-shaped groove rack and a support groove in the door-shaped groove rack, and the door-shaped groove rack is communicated with the support groove in the door-shaped groove rack to form a communicated groove. The preparation method includes that manufacturing an expanded view of the seat framework groove, and cutting a continuous fiber thermoplastic composite plastic sheet according to the expanded view shape; heating the sheared sheet; using at least one layer of heated sheet to cover a female die of the seat framework, wherein a groove of the female die is placed at the middle of the sheet; using a male die of the seat framework to press the sheet into the female die, and demoulding. The seat surface of the seat uses continuous fiber and long fiber, by means of the set, the arrangement and orientation of the fiber supplement each other, and the specific strength, specific modulus and impact resistance of the seat surface are greatly improved. A reinforcing rib uses long fiber, and the phenomenon that fiber is easy to break in the compression moulding process is avoided.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a continuous fiber thermoplastic composite plastic seat frame and a preparation method thereof. Background technique [0002] With the lightweight requirements of products in the automotive industry, customers have also put forward stricter requirements on the weight of products. Most of the backrest frames used in passenger car seats on the market are metal backrests, the processing procedures are complicated, and more man-hours are spent. In terms of energy consumption, the production of plastic raw materials can save more energy than the production of metal raw materials. The cost of reuse is small, and it hardly causes pollution to the environment. It has the advantages of small density, small linear expansion coefficient of thermoplastic composite materials, and can reduce the shrinkage rate in the process of product molding (can improve the precision of product size)...
