Composite Ribbon Laying Apparatus and Method Using Laser

Abstract

The invention relates to a composite material ribbon laying device using laser, which has a tape unwinding roll, a glue roller, a guide unit and a pressure roller, wherein a laser device is also included, which is arranged to be able to face the processed member and the composite material ribbon The bonding part of the laser beam is used to scan point-by-point the bonding surface of the composite material ribbon laid on the processed member by using the laser beam, so that the thin layer on the surface of the scanned area undergoes a photopolymerization reaction and reaches a cured state. According to the present invention, the continuous laser curing process is used to scan the surface of the ribbon of the composite material point by point during the laying process of the composite material to make it reach a solidified state, and then press it with a pressure roller to form the profile of the product.

Description

technical field [0001] The invention relates to a composite material ribbon laying device using laser and a method thereof, which are used in the field of aviation manufacturing to use a laser device to assist in laying composite material ribbons for aircraft, and belong to the application field of laser technology.

Problems solved by technology

However, electron beam curing technology uses electron beams as a heat source and requires a high-vacuum environment to prevent electron scattering. A vacuum chamber with a specified space must be installed on the processing table, which greatly affects the flexibility of processing. In addition, The required vacuum time also seriously reduces the production efficiency

[0005] In addition, in order to ensure better adhesion between the prepreg yarn bundle (or narrow tape) and the original layer on the mold, and to prevent air bubbles and ensure product quality , Special process equipment is required to make prepreg yarn bundles (or narrow tapes), so the manufacturing process is complicated and the manufacturing cost is increased
