Embodiment 1

[0031] Embodiment 1 Select each raw material according to the following weight ratio: 50 kg of o-phthalic unsaturated polyester resin, 30 kg of thick bamboo fiber, 18 kg of light calcium carbonate additive, and 2 kg of cobalt naphthenate as a curing agent. The rough bamboo fiber is obtained by mechanically extruding and screening bamboo materials.

[0032] The o-phthalic unsaturated polyester resin is formulated into a solution, mixed evenly with thick bamboo fiber and light calcium carbonate, and put into a mold together, and the temperature is slowly raised to polymerize and solidify the polyester resin under the action of a curing agent. Then, the mold is demoulded, and the cutting process is carried out to obtain the structural part of the bamboo fiber glass fiber reinforced plastic material. The structural part has the properties of light weight, corrosion resistance and high strength, and can be used as an automobile instrument panel and a civil anticorrosion engineering...

Abstract

The invention relates to plant fiber compound glass steel materials including unsaturated polyester resin. The invention is characterized in that the weight percentage for the raw materials of the plant fiber compound glass steel materials is as follows: 30 to 80 percent of unsaturated polyester resin, 5 to 64.8 percent of plant fiber, 5 to 45 percent of additive, and 0.2 to 5 percent of curing agent. The plant fiber compound glass steel material uses abundant plant fiber to replace glass fiber to be a matrix and ode type material of the glass steel material, thereby effectively reducing the raw material cost, and synchronously the glass fiber has the good performance of the glass fiber reinforced glass steel material. The matrix of the wasted glass steel materials is easy to be corrupted, thereby effectively reducing the pollution to environment by glass steel wastes. The plant fiber compound glass steel materials can be widely used for the components manufacturing of the bumper, the switch board, the engine cover, the baggage cabin, the lamp frame, the car door and the car shell of a car, and the manufacturing of ship components, civil work anticorrosion projects, construction and road administration facilities as well as sporting goods.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular designs a composite material which uses plant fibers instead of glass fibers to make FRP and a preparation process thereof. Background technique [0002] As a composite material with superior performance, FRP material has been widely used in many fields. It is not limited by the properties of specific materials, so different component materials can be selected to design composite materials with functions such as light weight, high strength, anti-corrosion, insulation, wear resistance, and fire prevention. Commonly used FRP composite materials use glass fiber as the reinforcing material of the unsaturated polyester resin matrix. It has the advantages of corrosion resistance and high strength, and can be used to replace metal and other composite materials for the manufacture of pipes, structural parts, containers, etc. [0003] Although the glass fiber reinforced plastic mater...
