Abstract
The invention discloses a layer structure composite material bumper with a panel composite function and a production method thereof. The bumper comprises a panel and a fiber reinforcement composite layer plate, wherein the panel is bonded with the fiber reinforcement composite layer plate; the fiber reinforcement composite layer plate consists of a plurality of fiber reinforcement composite material layers and a plurality of layers of resin matrixes; the fiber reinforcement composite material layers are obtained by laminating layers; and fibers in the fiber reinforcement composite material layers are coated with the resin matrixes. According to the bumper disclosed by the invention, the volume percent of the fiber reinforcement composite material layers is 20-80 percent. According to the production method disclosed by the invention, the bumper is produced by adopting a laminating and gluing process and a pressing and forming process. According to the bumper disclosed by the invention, the designability of the fiber reinforcement composite material and the decoration and impact resistance of the panel are fully utilized, the weight of the bumper is reduced, the appearance of the bumper is improved, the collision safety of various automobiles is improved and passersby and passengers are protected.
Description
Technical field
The present invention relates to the bumper/spoiler that a kind of auto trade is used, more particularly say, be meant a kind of compound layer structural composite material bumper/spoiler of panel that has.The preparation bumper/spoiler has adopted shop layer coating technique-extrusion forming technology.
Background technology
Auto trade is to bumper/spoiler safety, energy-conservation and environmental protection requirement is increasingly high; And composite material has advantages such as high specific stiffness, high specific strength, high tenacity, shock-resistant, processibility, high fatigue performance, high damage tolerance performance, withstanding corrosion; Both the vehicle safety performance requirement can be satisfied, the automobile lightweight requirements can be satisfied again.
Summary of the invention
The purpose of this invention is to provide a kind of compound layer structural composite material bumper/spoiler of panel that has; This bumper/spoiler utilizes the outstanding designability of fiber reinforced composite; Collision performance to different automobile types requires, cost requirement; Can make the bumper/spoiler of dissimilar high-impact complex fiber materials, improve crash survivability, protection pedestrian and the passenger of various vehicles.
A kind of compound layer structural composite material bumper/spoiler of panel that has of the present invention, this bumper/spoiler comprises panel and fiber-reinforced composite laminate, panel and fiber-reinforced composite laminate are bonding.The fiber-reinforced composite laminate places the top of panel.The fiber-reinforced composite laminate places the below of panel.The fiber-reinforced composite laminate place two panels between.
A kind of compound layer structural composite material bumper/spoiler of panel that has of the present invention; Said fiber-reinforced composite laminate is made up of multi-layer fiber layers of reinforcement and multi-layer resinous matrix; Said multi-layer fiber layers of reinforcement is shop layer gained, and said resin matrix is on the fiber that is coated in the said fibre reinforced materials layer;
This bumper/spoiler includes upper layer fibre reinforced materials layer (10) particularly; Following surface layer fibre reinforced materials layer (20); And be first resin matrix (201) to arranging in order between the surface layer fibre reinforced materials layer 20 down from upper layer fibre reinforced materials layer (10); The first fibre reinforced materials layer (101); Second resin matrix (202); The second fibre reinforced materials layer (102); The 3rd resin matrix (203); The 3rd fibre reinforced materials layer (103); The 4th resin matrix (204); The 4th fibre reinforced materials layer (104) and the 5th resin matrix (205).
