Embodiment approach

[0052] Clause 1. A method of manufacturing a composite structure, the method comprising:

[0053] molding a thermoplastic resin first part reinforced with discontinuous fibers;

[0054] laying down a second part of thermoplastic resin reinforced by substantially continuous fibers; and

[0055] The thermoplastic resin first member and the thermoplastic resin second member are co-welded.

[0056] Clause 2. The method of clause 1, wherein molding the thermoplastic resin first part is performed by compression molding a flowable mixture of thermoplastic resin and discontinuous, randomly oriented fibers.

[0057] Clause 3. The method of clause 2, wherein said compression molding comprises:

[0058] placing a certain load of thermoplastic prepreg in the mold;

[0059] forming a flowable mixture of resin and fibers by melting a thermoplastic resin in the prepreg; and

[0060] The flowable mixture within the mold is compressed.

Abstract

The invention relates to a composite structure, a method for manufacturing the composite structure and a hybrid composite structure. The hybrid composite structure includes a molded thermoplastic composite component and a laminate thermoplastic composite component co-welded together. The molded component is reinforced with discontinuous fibers, and the laminate component is reinforced with continuous fibers.

Description

[0001] This application is a divisional application of an invention patent application with an application date of December 1, 2014, an application number of 201410718019.X, and an invention title of "composite structure, method for manufacturing the composite structure, and hybrid composite structure". technical field [0002] The present invention relates to composite structures, methods of making the same, and hybrid composite structures. Background technique [0003] In aircraft and other industries, composite structures such as beams and spars are constructed using the thermoset prepreg tapelayup technique and autoclaved steam curing. Wide strips of prepreg tape or tow are laid side by side to form a multilayer laminate that is vacuum bagged and cured with high pressure steam. In some applications where the structure needs to be joined at the load input location, custom metal fittings are machined separately and then fastened to the laminate structure. Laminate structu...
