Description
Technical Field
The present invention generally relates to the field of thermoplastic composites. More particularly, the present invention relates to the assembly of thermoplastic composite sub-components by compression molding processes to produce fully functional or finished parts.
Background
Thermoforming is a manufacturing process that heats a thermoformable material to a sufficient temperature that allows the heated thermoformable material to be molded, such as by injection molding, and cooled to a final shape. The advantage of using thermoformable materials for manufacture is that they can be treated with heat.
The thermoformable composite is a combination of a fibrous reinforcement and a resin matrix. The resin matrix may be a thermoset material or a thermoplastic material. Thermoplastic composites are a combination of thermoplastic material (referred to as thermoplastic resin or thermoplastic resin matrix) and reinforcing material (such as individual fibers or fabrics made from fibers). Exemplary fibrous materials include, but are not limited to, carbon, glass, aramid, polyester, jute, cellulose, and cotton. An exemplary thermoplastic compound is Continuous Fiber Reinforced Thermoplastic (CFRT). After the material has been set, the thermoplastic material comprising the thermoplastic composite may be reshaped or reprocessed. Exemplary thermoplastic materials include, but are not limited to, Polycarbonate (PC), formable PET (polyethylene terephthalate), polyamide, polyphenylene sulfide, polyetherketone, and etherketone. A thermoset composite is a combination of a thermoset material (referred to as a thermoset resin or thermoset resin matrix) and a reinforcement material. Thermoset materials comprising thermoset composites cannot be set after curing, even after heating. Exemplary thermosets include, but are not limited to, polyesters and epoxies.
In many applications, it is desirable to manufacture a subassembly that is an assembly of a thermoformed composite part and another part. The assembly of such components may be achieved by adhesive bonding or mechanical joints. In the case of thermoset composites, once the thermoset composite part is formed, it is difficult to further process, such as bonding to another part. Thermoset composites can be used to make integral assembly features for mechanical joints because thermoset resins are low viscosity liquids that work well to wet the complex 3D fiber reinforcement necessary to form such mechanical joints in thermoset composite parts. Examples of such assembly features include, but are not limited to, studs, fasteners, or threaded inserts. While it is effective to integrally form component features on thermoset composite parts, thermoset materials have longer cycle times, fewer material choices, and higher costs than thermoplastic materials. As a result, thermoplastic and thermoset composite parts have become more popular. However, with thermoplastic materials, it is difficult to use the 3D fiber reinforcement necessary to form the integral assembly features on the thermoplastic composite part. In particular, it is difficult to manufacture integral assembly features, such as protruding studs, using normal compression molding processes used in the manufacture of thermoplastic composite parts. In order to make mechanical joining of a thermoplastic composite part with another part feasible, a threaded hole may be formed in the thermoplastic composite part, but sometimes the hole may break the surface continuity of the fiber reinforcement and also create a weak point in the thermoplastic composite part. To attach an assembly feature (such as a stud, fastener, or threaded insert) to a thermoplastic composite part, it is not as easy as simply drilling a hole. Methods have been developed to attach assembly features to thermoplastic composite components.
Since the thermoplastic composite may be reprocessed, such as overmolded, after the thermoplastic composite part is formed, assembly features may be added after the thermoplastic composite part is formed. For example, after forming the thermoplastic composite, an overmolding process may be performed to add component features. One conventional method for adding assembly features to an already formed thermoplastic composite part is to separately add each new assembly feature at each new assembly feature location using an injection molding process. A mold for each new assembly feature is positioned against the thermoplastic composite component at each of the assembly feature locations and injection molding a injection molding material into each mold that is bonded to the thermoplastic composite component. However, in applications where many new component features are to be added, this can be a very time consuming and inefficient process. Another conventional method for adding new assembly features to an already formed thermoplastic composite part is to place the formed thermoplastic composite part into a tool and then perform a back injection molding process to form any desired assembly features. A disadvantage of this back-injection molding process is that a large amount of wasted material is required to form the assembly features, which also adds weight to the thermoplastic composite part.
The back injection molding process is a form of injection molding. The thermoplastic composite component is formed with a back-injection molding input opening and a network of channels extending from the single input opening to each of the locations on the thermoplastic composite component in which the assembly features are to be formed. There is an output opening in the thermoplastic composite part at each assembly feature location. A large mold having a plurality of individual molds (one mold corresponding to each assembly feature and aligned with a respective output opening in the thermoplastic composite component) is positioned over the thermoplastic composite component. Injection molding material is injected into the input openings and distributed through the channels to each of the output openings where it is injected into each individual mold. The injection molding material injected into each individual mold forms one of the component features. However, the injection molding material present in the channel extending from the input opening to the output opening is a waste material. The further the assembly features are spaced from each other, the more waste injection molding material is wasted.
Other conventional methods for adding assembly features to thermoplastic composite components have been developed. EP 0903216a2 discloses the overmolding of a steel insert with claws, which can be anchored in a thermoplastic composite part. In US 6682675B 1, a co-moulding process of a thermoplastic material with a thermoplastic interlayer material is disclosed. The molded article can be easily attached to another article (e.g., a vehicle body). In US 8197624B 2, a welding process is disclosed. This process joins together thermoplastic polymers and thermoset polymer composite parts having a thermoplastic surface layer by using high frequency vibration. In US 9180681B 2, a cylindrical insert having a circumferential groove is molded in thermoplastic composite compression molding, the groove surrounded by the thermoplastic composite forming a mechanical interlock to retain the insert in the thermoplastic composite. In US 9302434B 2, a thermoplastic prepreg sheet is used to manufacture composite parts with molded inserts. In US 9586362B 2, a thermoplastic welding device is disclosed which uses an induction coil and at least one smart susceptor. In US 9610654B1, a method and apparatus for joining thermoplastic composite parts is disclosed that uses compliant induction coils embedded in a plurality of elastomeric sheets. In US 9770892B 2, an apparatus is disclosed for welding two thermoplastic composite parts together, which uses a double sided inductor and a field absorber.
Generally, conventional methods of manufacturing thermoplastic composite parts having assembly features first manufacture the thermoplastic composite part and then perform an overmolding process to add the assembly features. While there are many different ways to attach the different features of the assembly, there are no conventional methods for directly attaching nuts or screws using compression molding.

It will of course be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with application-and business-related constraints, which will vary from one implementation to another and from one developer to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for those of ordinary skill in the art having the benefit of this disclosure.
The thermoplastic composite component assembly includes one or more assembly features integrally formed with the thermoplastic composite component, although the one or more assembly features and the thermoplastic composite component are initially manufactured separately as discrete components. An assembly feature is a mounting feature that enables a thermoplastic composite component assembly to be assembled, mounted, connected, joined, attached, or similarly coupled (collectively "assembled") to another discrete component having a complementary assembly feature.
In a manufacturing process for manufacturing thermoplastic composite component assemblies, discrete assembly feature components are manufactured separately from the manufacture of the thermoplastic composite component. The separately manufactured assembly feature component is then integrally combined with the thermoplastic composite component using a compression molding process. FIG. 1 illustrates an exemplary manufacturing process for manufacturing a thermoplastic composite component assembly, according to some embodiments. Thermoplastic composite components may be manufactured using one or more discrete thermoplastic composite layers combined together. Each thermoplastic composite layer is a combination of a thermoplastic material and a reinforcing material of the type previously described. In the exemplary process shown in fig. 1, N thermoplastic composite layers are used. In some embodiments, each thermoplastic composite layer is made from a fabric-thermoplastic prepreg (a fiber reinforcement in the form of a fabric) or a unidirectional thermoplastic prepreg (a fiber reinforcement made from individual fibers aligned in a single direction).
In step 6, the N thermoplastic composite layers are laminated together by pre-consolidation to form a laminated thermoplastic composite layer 8. During the pre-consolidation process, all layers of the composite are not pressed together completely, they simply form a loosely attached preform for ease of handling during the compression process. In some embodiments, lamination is performed using heat and pressure to bond the N thermoplastic composite layers together. At step 10, a first compression molding process is performed on the laminated thermoplastic composite layers 8 using a first compression molding tool at a suitable pressure and temperature to form a thermoplastic composite component 12 having a molded shape. The pressure is controlled by the molding tool and associated machinery, and the temperature is a function of the composite properties. In some embodiments, the first compression molding tool is a different tool than the tool used for lamination performed in step 6. Discrete assembly feature components are manufactured separately from the thermoplastic composite part 12. In an exemplary embodiment, one or more of the assembly feature components are molded threaded inserts. The following description is based on such a molded threaded insert. It should be understood that alternative types of assembly feature components may be manufactured and used, such as studs, fasteners, or other types of threaded inserts. The molded threaded insert may be manufactured by first obtaining the threaded insert part 14 and then overmolding the threaded insert part 14 with the thermoplastic layer 18, such as by using an injection molding process at step 16. It should be understood that an alternative conventional overmolding process may be used to form the thermoplastic layer 18 over the threaded insert 14. The result is a molded threaded insert, shown as assembly feature component 20.
Fig. 2 shows a cut-away side view of the molded threaded insert 20. An overmolded thermoplastic layer 18 is embedded in the threaded insert 14. At one end of the thread, the bore of the threaded insert 14 is open, while at the other end there is additional thermoplastic material 32 forming a cap. The additional thermoplastic material 32 is the base of the molded threaded insert 20, where the base is positioned against an assembly feature on the thermoplastic composite component. In some embodiments, the thickness of the additional thermoplastic material is in the range of 0.5 to 2 mm. It should be understood that thicknesses less than 0.5mm and greater than 2mm may be used. To enhance the bond strength of the base to the underlying thermoplastic composite component 12, the base of the molded threaded insert may have a fillet or chamfer of a diameter greater than the body.
Returning to FIG. 1, at step 22, one or more of the manufactured assembly feature parts 20 are positioned on the respective assembly feature locations of the thermoplastic composite part 12. In some embodiments, a second compression tool is used to bond the assembly feature component 20 to the thermoplastic composite component 12. The discrete assembly feature components 20 are placed in a second compression tool with the formed thermoplastic composite component 12. The second compression tool is configured for positioning and aligning the formed thermoplastic composite part 12 in a particular first position and has a specifically positioned cavity corresponding to each assembly feature location. Each cavity is configured to receive a respective one of the discrete assembly feature components 20. At step 24, once the second compression tool is loaded with the formed thermoplastic composite part 12 in the first position and the discrete assembly feature parts 20 are loaded in the cavities, the second compression tool is heated to a particular temperature and compression is applied to compress each discrete feature part 20 to the thermoplastic composite part 12 at each assembly feature location. In connection with the exemplary molded threaded insert 20, additional thermoplastic material 32 is bonded to the thermoplastic composite component 12. FIG. 3 shows a cut-away side view of the molded threaded insert 20 bonded to the thermoplastic composite component 12. As shown in fig. 3, the base of molded threaded insert 20, formed of additional thermoplastic material 32, is bonded to thermoplastic composite component 12 at assembly feature location 34. At each assembly feature location, the thermoplastic material at the interface between each discrete assembly feature component and the thermoplastic composite material used to form the thermoplastic composite component melts or reflows, which upon cooling substantially "welds" each discrete assembly feature component to the thermoformed thermoplastic composite component. One aspect of this process is to manage the amount of thermoplastic material at each feature site interface to control the weld. Another aspect of this process is to precisely control the temperature applied to the assembly feature components 20 and the thermoplastic composite component 12 to enable each assembly feature component 20 to be bonded to the thermoplastic composite component 12 while maintaining the integrity of the thermoplastic composite component 12. To ensure the success of the bonding process, the thermoplastic layer of the molded threaded insert should be compatible with the thermoplastic resin matrix of the thermoplastic composite part. The interface area between the molded threaded insert and the composite also determines the bonding force. In an exemplary application, nine layers of carbon fiber thermoplastic prepreg are used, the thermoplastic resin matrix of the thermoplastic composite is polycarbonate, and the thermoplastic used to overmold the threaded insert is also polycarbonate. The molded threaded insert had a threaded insert size of ISOM4 × 0.7, an outer diameter of 6mm, and an overmolded thermoplastic layer surrounding the threaded insert was 10mm in diameter. The tested bond force between such molded threaded inserts and thermoplastic composite components is greater than 1000 newtons.
The present application has been described in terms of specific embodiments incorporating details to facilitate the understanding of the principles of construction and operation of thermoplastic composite component assemblies and methods of manufacture. Many of the components shown and described in the various figures can be interchanged to achieve the results necessary, and this description should also be read to encompass such interchange. Therefore, references herein to specific embodiments and details thereof are not intended to limit the scope of the claims appended hereto. It will be apparent to those skilled in the art that modifications may be made in the embodiment chosen for purposes of illustration without departing from the spirit and scope of the application.
