How to Get Involved
Students engage with NWI by partnering with faculty from the degree program of their choice. Research projects are developed by faculty and selected by NWI member companies. Students are selected based on their academic performance and capability within the industry-selected research programs. Proposal selection is a competitive process, and NWI does support the submission and selection of research proposals from faculty at other universities.
NWI supports students from a number of NC State academic programs including Fiber and Polymer Science, Chemical and Biomolecular Engineering, Mechanical and Aerospace Engineering, Materials Science and Engineering, Forest Biomaterials, and Biomedical Engineering, as well as students in various engineering programs at partner institutions in the United States and globally.
Our students will graduate with a degree in the discipline to which they are admitted, but their research will be focused on a topic of relevance to nonwovens.
Process for NWI Assistantship:
The Industrial Advisory Board
The Industrial Advisory Board (IAB) is responsible for the governance of the NWI Consortium, which is comprised of our Members, participating Faculty and Principal Investigators (PIs), and the Students who are engaged in NWI research projects.
The IAB meets semi-annually in the Spring (May) and Fall (November). The first half-day and full second day of the IAB meeting are designed for Core Research Presentations and Reviews. The morning of the third day is for the Members’ Business Meeting, where the Core Research Presentations will be discussed and evaluated by NWI membership.
For the Core Research Presentations & Reviews portion of the IAB meeting, students engaged in the NWI program must prepare:
- A written semi-annual research report
- A one-page description of their research
- A PowerPoint presentation on their research
- A research poster
During the first IAB meeting after initiating a project, the PI and student are responsible for submitting a poster, a one-pager and report; and thereafter, it is mandatory that the PI and the student submit a report, a one-pager, a presentation and a poster.
Student presentations at the IAB meeting should cover the following:
- Project goals
- Project relevance to the industry
- Status at last report
- Overview of the presentation
The presentation must follow the template provided by NWI (see below). The presentation should be planned for the time duration shown on the agenda, including approximately five minutes for questions.
Please make sure that you meet the deadlines for the submission of reports and presentations. Reports and Presentations received after the deadline will not be distributed to the member companies. No exceptions will be made.
