The new product development process (NPDP) is crucial for maintaining business up and running in manufacturing corporations worldwide. NPDP helps firms improve their profits, where stakeholder attention is mostly focused. NPDP Risk Assessment (NPDP-RA) is a vital activity to achieve a successful new product launch. However, managing different kinds of risks over the process presents enormous challenges; thus, risk assessment over NPDP still shows gaps, even when different tools are employed to identify, mitigate, and eliminate risks throughout the process. The identified gaps are mainly produced because the uncertainty added by the individuals assessing the risks, and the currently used tools are generally focused on a single phase of the NPDP, disregarding the stakeholders' project objectives. This paper presents the main NPDP risks for stakeholders through the NPDP phases; likewise, the integration of Pythagorean fuzzy dimensional analysisfailure mode and effect analysis and value stream mapping (PFDA-FMEA-VSM). This novel integrated method is intended to improve the manner to perform the NPDP-RA for stakeholders. A practical example is presented to demonstrate the proposed integration of PFDA-FMEA-VSM for stakeholders at NPDP of electronic devices project.
Additive manufacturing represents an alternative that offers great advantages in small-scale production, high level of customization and ease of building complex geometries. However, rapid prototyping parts present mechanical limitations that prevent their use in applications that require greater resistance.
In the present work an experimental analysis was carried out where the processes of Resin Infusion and Hand Lay-Up were compared, performing tests with specimens constructed according to the ASTM D790-17 standard, for laminated material of carbon fiber with plastic nuclei by prototyping fast and tested with two orientations of fibers "3k", (-45? +45? and 0? 90?).
The tests and the statistical analysis of the data were made based on a factorial design, generating results that offer acceptable levels of stiffness and deflection without causing delamination failures, obtaining a combination that allows the manufacture of a piece without the need for a mold. The material constructed by Hand Lay-Up offered the best performance, by not failing by delamination.
Key Words: additive manufacturing, composite materials, bending tests, fused deposition modeling, ABS, delamination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
