Abstract

The invention discloses a fiber-reinforced composite material and a preparation method thereof, belongs to the field of composite materials, and solves the technical problems that an existing ACM composite material has the poor impact resistance and is easily damaged, and the intensity of the ACM material is low due to distortion and deviation in a spot. The fiber-reinforced composite material is in a multi-layer structure, a base layer is made of glassfiber reinforced plastics, and the outer surface of the base layer is sequentially provided with a gel coat resin layer, a transparent paint layer and a film layer from inside to outside. The glassfiber reinforced plastics is prepared from a fiber-reinforced phase, polyester resin and a curing agent by utilizing a resin transfer molding process. The fiber-reinforced composite material can be manufactured to modular products such as corporate logos, oil price labels, beautiful logos of commodity of convenience stores, and the like.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to fiber-reinforced composite materials and a preparation method thereof. Background technique [0002] At present, in the design and construction of domestic refueling station projects, in addition to the design of station buildings (convenience stores, financial offices, offices), refueling process equipment and facilities, it also includes canopies, oil price signs, lighting fixtures, and facilities for convenience stores. Decoration and other designs. The overall design of the refueling station is sturdy and durable, the exterior decoration is bright and colorful, and the business atmosphere is strong, which often plays a role in attracting customers. Therefore, it is a new requirement put forward by many entrusted builders of refueling stations. [0003] The traditional canopy design mainly uses aluminum composite material (Aluminum Composite Matera for short ACM) board as t...
