Cyanate resin/ carbon fiber composite material and its preparing process

Abstract

The invention discloses a making method of cyanate resin / carbon fiber composite material, which comprises the following steps: 1) heating and fusing cyanate resin to form transparent pattern under 80-100 deg.c; insulating 1-3h; adding 1-3% carbon nanometer pipe; insulating under 80-150 deg.c for 2-4h; cooling to indoor temperature; obtaining resin base; 2) adding acetone in the resin base with bulk rate at 1:0.8-1:1.2; allocating glue solution; immersing carbon fiber or carbon fiber cloth in the glue solution; drying; doing hot pressing to mould after the quantity of volatile substance is less than 1%; obtaining the product.

Description

technical field

[0001] The invention relates to a composition of thermosetting resin and carbon fiber and a preparation method thereof, in particular to a cyanate resin / carbon fiber composite material. Background technique

[0002] Cyanate ester resin (Cyanate Ester, CE) is a high-performance thermosetting resin matrix developed in recent years. It has outstanding dielectric properties in a wide frequency range, and has extremely low water absorption, excellent heat resistance and The combination of mechanical properties and excellent processability, these attractive properties make it show great potential in the preparation of structure / function integrated resin matrix composites.

[0003] In order to enhance the strength of the resin, reinforcing materials are usually added to the resin matrix to form a composite material. The commonly used reinforcing material is carbon fiber, which can be added directly or carbon fiber cloth. The performance of composite materials is no...
