Abstract

This invention is related to the interface modified method of aromatic fiber reinforced poly phthalazinone ehter sulfone ketone (PPESK) compound, using low-temperature plasma technology. The processed conditions are as follows: the atmosphere is oxygen, nitrogen, air, free ammonia or argon, the power is 10-400W, the time is 1-30 minutes, and the atmospheric pressure in the processing cavity is low pressure of 1-100Pa, normal pressure or high pressure of 1.01*105-106Pa. Etching the surface of Armoc aromatic fiber and modifying it by grafting, impregnating the modified Aromc aromatic fiber and the PPESK emulsion of 5-50% part by weight to prepare the prepreg of one-way fiber reinforced PPESK compound, and then preparing the said compound by using hot-pressed molding technology. The modified Aromc aromatic and the PPESK base can form a good interface layer, furthest realize the integrated performance of the compound, which is capable to meet the operating requirements of heat resistance and implement commercial processes in batch, continuity and large scale.

Description

technical field

[0001] The invention belongs to the scientific and technical field of advanced composite materials, in particular to a method for improving the interfacial properties of aramid fiber reinforced polyarylether sulfone ketone resin-based composite materials through low-temperature plasma technology. Background technique

[0002] The fiber-reinforced thermoplastic resin matrix composite material is composed of two parts, the reinforcing fiber and the thermoplastic resin matrix, and the interface is formed between the two parts. The composition, properties, bonding mode and bonding strength of the interface have an important influence on the mechanical properties of composite materials. The stress transfer between the fiber and the matrix in the composite mainly depends on the shear stress of the interface, and the ability to transfer the stress depends on the performance of the interface. Form an effective interfacial bond between them. The interface is an extr...
