Abstract

The invention discloses a preparation method of a fiber reinforced thermoplastic resin based composite automobile hub. The composite automobile hub comprises a spoke and a rim, wherein the rim adopts pultrusion thermoplastic composite prepreg, and the spoke adopts a hot-pressing molding blank. The preparation method comprises the following steps: firstly, preparing the pultrusion thermoplastic composite prepreg; adopting the pultrusion thermoplastic composite prepreg for the preparation of the hot-pressing molding blank, pre-cutting the hot-pressing molding blank into a rim structure, then placing the hot-pressing molding blank with the rim structure between an inner mould and an outer mould with rim-shaped structures, performing hot-pressing to obtain a rim hot-pressed blank, winding the pultrusion thermoplastic composite prepreg onto the rim hot-pressed blank and the inner mould with the rim-shaped structure, closing the outer mould and the inner mould, heating, cooling, opening mould, and trimming, so as to obtain the automobile hub. According to the preparation method provided by the invention, the mass production of the complex automobile hub can be implemented, the production cost is reduced, and the application of a composite in the automobile lightweighting is greatly facilitated.

Description

technical field [0001] The invention belongs to the technical field of composite materials, in particular to a method for preparing a fiber-reinforced thermoplastic resin-based composite automobile wheel hub. Background technique [0002] Composite materials have the characteristics of high specific strength, high rigidity, and strong designability. Using composite materials to prepare automobile hubs can greatly reduce weight while making the wheel hubs have good shock absorption performance and toughness, and improve the strength and strength of the wheels. Safety, in order to achieve the purpose of energy saving and emission reduction. [0003] In 2008, the concept car launched by Japan's Weds Sports used carbon fiber wheels for the first time. But still at the concept stage. [0004] In 2009, Australia's Carbon Revolution developed the CR9 "one-piece" all-carbon fiber composite wheel, which is 40%-50% lighter than aluminum alloy wheels, and it was first applied to the ...
