Abstract

The invention discloses a reinforcing sheet designing and a reinforcing method for a thermoplastic fiber composite material tapping component. Specifically, a matched reinforcing sheet with a radial fiber track layer and an annular fiber track layer is designed according to the shape and the size of the tapping component; and then the reinforcing sheet is used for reinforcing the thermoplastic fiber composite material tapping component. The reinforcing sheet has the advantages of simplicity and convenience in design, excellent reinforcing effect, no cutting, mass production and the like. When the reinforcing sheet performs a reinforcing action, the molding process is simple and flexible, and the reinforcing efficiency is greatly improved, so that the reinforcing sheet has a very wide application prospect.

Description

technical field [0001] The invention relates to the technical field of thermoplastic composite materials, in particular to a method for manufacturing a reinforcing sheet at an opening part for improving the performance of a thermoplastic composite material with openings, and a method for reinforcing the opening part with the reinforcing sheet. Background technique [0002] Fiber-reinforced thermoplastic composites have high specific strength, high specific modulus, fatigue resistance, corrosion resistance, strong designability, high toughness, no storage time limit, short manufacturing cycle, low moisture absorption, weldable, repeatable processing, etc. The series of excellent performance are widely used in aerospace, navigation, national defense, transportation, civil engineering, energy, chemical machinery, sports and entertainment and other fields. In practical applications, thermoplastic composite laminates often need to open holes for reasons such as component connecti...
