Abstract

The invention discloses a PET (polyethylene terephthalate) waste fiber / bamboo fiber reinforced unsaturated polyester composite material and a preparation method thereof. The method comprises the following steps: modifying the surface of a PET fiber felt and the surface of a bamboo fiber felt by using a plasma technique, and performing hot-press molding on the modified PET fiber felt, the modified bamboo fiber felt, unsaturated polyester resin, a cross-linking agent, an accelerant and an initiator so as to obtain the modified PET waste fiber / bamboo fiber reinforced unsaturated polyester composite material. The prepared PET waste fiber / bamboo fiber reinforced unsaturated polyester composite material and a modified PET waste fiber / bamboo fiber reinforced unsaturated polyester composite material disclosed by the invention are both high in tensile strength, bending strength and bending modulus.

Description

technical field [0001] The invention belongs to the technical field of fiber-reinforced resin composite materials, and in particular relates to PET waste fiber / bamboo fiber reinforced unsaturated polyester composite materials and a preparation method thereof. Background technique [0002] With the increasing sales of PET (polyethylene terephthalate), the amount of discarded PET fibers has increased sharply, resulting in waste of resources and environmental pollution, especially PET scraps and wastes used in the manufacture of high-temperature filter materials. Because the surface of the fiber is modified by inorganic substances, the discarded PET fiber cannot be melted and recycled, and can only be discarded as a landfill. PET waste fiber is chemically inert and is not easily degraded in a short period of time when exposed to nature, occupying a lot of space. Therefore, its recycling is increasingly subject to people's attention. PET fiber has good tensile strength and tou...
