Abstract

The invention belongs to the technical field of thermoplastic materials, and in particular relates to a preparation method for a melted connection joint of fiber reinforced PBT composite materials. The invention provides the preparation method for the melted connection joint of the fiber reinforced PBT composite materials by using the characteristic of very low melt viscosity of CBT, namely a new melting connection technology of heating a resin matrix in a surface to be connected of the composite materials to be partially melted and then cooled and consolidated is used to provide a connecting technology and method for preparing large components made of PBT composite materials. Compared with the traditional thermoplastic composite material connection technology, the preparation method for the melted connection joint of the fiber reinforced PBT composite materials is the process with high performances and low cost, and further can be used for producing lightweight, high-strength and large-sized connecting structures of thermoplastic composite materials.

Description

technical field

[0001] The invention belongs to the technical field of thermoplastic materials, and in particular relates to a preparation method of a fiber-reinforced PBT composite material fusion connection joint. Background technique

[0002] Thermoplastic composite materials have good toughness and impact resistance, and have the advantages of short molding cycle, low manufacturing cost, recyclable waste, and secondary processing of products. They have been widely used in various industrial fields in recent years. However, the high melt viscosity of traditional thermoplastic resins makes it difficult to fully impregnate reinforcing fibers and prepare high-strength composite materials with high fiber volume content, which has always been a shackle that limits its application in medium and large main load-bearing components. .

[0003] The new high-performance thermoplastic cyclic butylene terephthalate (CBT) composite material provides the possibility for the development...
