Abstract

The invention discloses an automatic laying device for composite materials applied to curved surfaces, which includes a feeding device for conveying dry fiber filaments and resin films, and a hot press for heating the resin film and making it together with dry fiber filaments to form a semi-preg Roller unit, Tension and speed measuring unit for semi-preg tension and conveying speed, Spraying unit for spraying phenoxy powder, Shear torsion combination for clamping semi-preg Clamping device for deformation, cutting device for cutting semi-preg, winding device for recycling backing paper and compacting device for compacting semi-preg. The present invention utilizes the degree of freedom of torsion of the clamping device and the degree of freedom of movement of the compacting device along the belt width direction to cause shearing and torsion deformation of the semi-preg, thereby improving its ability to turn and lay on curved surfaces, avoiding its surface Defects caused by inner bending deformation.

Description

technical field [0001] The invention relates to the technical field of laying composite materials, in particular to an automatic laying device for composite materials applied to curved surfaces. Background technique [0002] Composite materials have the advantages of high specific strength, large specific modulus, fatigue resistance, and corrosion resistance. They are also suitable for the manufacture of large-scale and complex components, reducing the number of parts and the use of connectors, thereby reducing the quality of finished products. It improves the energy utilization rate and is widely used in aerospace, automobile and ship and other fields. Composite material automatic placement technology can improve production efficiency and ensure product performance, and is widely used in the manufacturing process of composite material parts. [0003] The automatic laying technology of composite materials can be divided into automatic tape laying technology and automatic wi...
