WPTO held its second webinar in the WPTO R&D Deep Dive Webinar Series. Professor David Miller gives a summary of marine hydrokinetic energy composites testing at Montana State University (MSU).
The primary structure of MHK energy devices have difficult and challenging environments for which fiber reinforced plastics are often considered. For cost benefits, glass fiber reinforced plastics (GFRP) are the most prevalent system under consideration. MSU and Sandia National Laboratory have performed research into the moisture effects on the stiffness, strength, and damage of GFRPs for many years. This talk presents a summary of a portion of this effort and also provides references to the thesis and conferences that contain the detailed information. The results include models of moisture absorption, effects of stress on moisture uptake, effects of moisture on damage modes and development, laminate stacking order effects, and culminates with moisture uptake effects on a large sample of industry collected coupons.
