Abstract

Recently, CFRP composites have become widely used as lightweight materials have excellent mechanical properties and can be used in various fields. In general, thermosetting resins are used for CFRP. However, in recent years, studies using thermoplastic resins have been actively carried out to overcome the disadvantages of thermosetting resins. LFT-D system is a molding method in which a fiber is directly cut to a desired length while being impregnated with a thermoplastic resin to produce a compound and press-molding the product.

 In this paper, before the production of the trailing arm, the compression molding analysis was carried out in order to grasp the problems that may occur during production. Through compression molding analysis was calculate of minimum press pressure and to compare and analysise molding conditions characteristic for forming the trailing arm.

Keywords: Compression Molding Analysis, LFT-D System
