Effect of Processing Parameters on Reliability of VARTM/SCRIMP Composite Panels - Phase 1
Abstract
Reliability based design and acceptance criteria are currently being developed by the U.S. Navy using Navy load and strength prediction methodologies. However, this work considers only traditional structural materials and systems and a limited range of structural-failure modes. Though limited, this effort represents a significant shift in composite design methodology and assessment of design acceptance and provides a framework used in this program. The structural risks associated with new FRP composite ship structures can be mitigated by characterizing the variability of composite material properties thus ensuring acceptable levels of safety. The objectives for work outlined in this report are as follows: 1) Identify apparent material variability resulting from ASTM test procedures; 2) Modify/recommend a series of coupon level test procedures that minimizes testing variability; 3) Develop a probabilistic finite element tool to predict material variability. Recommendations for material testing of marine grade woven roving fiberglass reinforced plastic materials have been presented.
