Embodiment Construction

[0018] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements. The embodiments are described below in order to explain the present invention by referring to the figures.

[0019] Such as figure 1 As shown, it is an object of the present invention to provide a method for manufacturing a plastic rear seat panel by integral injection molding of long glass fiber reinforced thermoplastic polypropylene (PP-LFT), compared to conventional rear seat panels manufactured by welding processed steel.

[0020] As a material forming the rear seat panel according to the present invention, a composite material (PP-LFT) including a polypropylene sheet reinforced with 30% long glass fibers was used instead of steel. The density of steel is 7.80g / cm 3 , while the density of high-strength plastic is 1.10g / cm 3 .

[0021] figure 2 A is a s...

Abstract

The present invention provides a method for manufacturing a plastic rear seat pan for a vehicle by integrally injection molding long-glass-fiber reinforced thermoplastic polypropylene (PP-LFT), which is a high-strength plastic material, to achieve reduction in vehicle weight and production costs. The method includes providing a composite material comprising a polypropylene sheet reinforced with 30% long glass fiber; and integrally injection molding the composite material in a desired shape to obtain an integrally formed plastic rear seat pan.

Description

technical field [0001] The present invention relates to a method of making a plastic rear seat panel of a vehicle. More specifically, the present invention relates to a method of manufacturing a vehicle plastic rear seat panel by integral injection molding of long glass fiber reinforced thermoplastic polypropylene (PP-LFT), which is a high-strength plastic material, thereby reducing vehicle weight and manufacturing cost. Background technique [0002] Due to the increasing demand for fuel efficiency, extensive research has been done on reducing the weight of vehicles. Hitherto, rear seat cushion frames for vehicles have been manufactured from steel using a welding process. [0003] The reason for providing a relatively heavy seat weight is to satisfy the user's desire for comfort and convenience and to actively respond to safety regulations that become stricter year by year. However, the increase in seat weight is a serious obstacle to reducing vehicle weight, which puts p...
