The general computer-aided design (CAD) software cannot meet the mould design requirement of the autoclave process for composites, because many parameters such as temperature and pressure should be considered in the mould design process, in addition to the material and geometry of the part. A framed-mould computer-aided design system (FMCAD) used in the autoclave moulding process is proposed in this paper. A function model of the software is presented, in which influence factors such as part structure, mould structure, and process parameters are considered; a design model of the software is established using object oriented (O-O) technology to integrate the stiffness calculation, temperature field calculation, and deformation field calculation of mould in the design, and in the design model, a hybrid model of mould based on calculation feature and form feature is presented to support those calculations. A prototype system is developed, in which a mould design process wizard is built to integrate the input information, calculation, analysis, data storage, display, and design results of mould design. Finally, three design examples are used to verify the prototype.

“…Most of these papers concentrated on specific types of manufacturing processes such as milling, machining, injection-molding processes and only a few dealt with polymer composite processes. Nagahanumaiah et al [2] provided a rule-based method to provide process selection and manufacturability evaluation for rapid tooling process. Ong et al [3] developed a fuzzy set-based manufacturability evaluation algorithm for the machining process, which generate relative manufacturability indices utilizing the method of analytic hierarchy process (AHP).…”

It is widely acknowledged that decisions made in the early design stages have a greater influence on the final product than those made in the later stages. In a conventional design process, composite products are designed without sufficient consideration being given to limitations of composite manufacturing process. Quite often some of composite designs cannot be produced with special performance requirement or cannot be produced at a reasonable cost. To resolve this drawback and achieve the competitive designs for composite product, an integrated knowledge framework that supports the quantitative manufacturability evaluation of composite design proposals was introduced. The essential concept of the composite manufacturability was defined through an in-depth analysis of composite manufacturing process. The evaluation flow was acquired according to the hierarchical indices. A stage-based quality assessment model for the composite multistage process was mainly studies. It relies on the consideration that the final quality of a composite product is mainly determined by some critical stages during a production cycle. Finally, the method is illustrated through a case focusing on the quality issue of void formation in autoclave process.

-Using Additive Manufacturing (AM) to produce inserts for injection molding of parts used for rapid quote can drastically reduce costs and time frame. Prototype injection molding currently can take weeks and thousands of dollars to develop and manufacture, making AM as a very viable option. Functional prototypes of mold inserts were developed and analyzed with CAD software, then printed on a 3D printer, and tested using industrial plastic injection molding equipment. Calculations for cooling and mold compression were used to develop guidelines for future parts. Measurements were taken on the molded parts in order to validate calculations and dimensions. This methodology is beneficial to industry because a company can rapidly and efficiently produce functional parts for quoting for prospective clients.
