Processing And Testing Commodity And Engineering Cfrtp Composites, Delia M. Derner, Kristine Osorio
Research & Creative Achievement Day
Commodity thermoplastic polymers provide good load transfer to and protection of the reinforcing fibers. However, their mechanical properties are inferior to high-performance thermoplastic polymer composites. Findings of preliminary research conducted at WSU showed that continuous fiber reinforced (CFR) commodity polymers such as PETG and PP have better Izod impact resistance than their high-performance CFR counterparts. Further investigation of these findings is conducted in this research project. Quasi-isotropic laminates of GF/PETG and GF/PET-am are fabricated and tested in drop weight impact. The results will be compared with previously determined results of high-performance CF/PPS, CF/PA12 and GF/PPS. The samples are fabricated using …
Low-Velocity Drop Weight Impact And Compression After Impact Properties Of Symmetric Quasi-Isotropic Cfrtp Composites, Youyi Zhou, Kyungbin Min
Low-Velocity Drop Weight Impact And Compression After Impact Properties Of Symmetric Quasi-Isotropic Cfrtp Composites, Youyi Zhou, Kyungbin Min
Research & Creative Achievement Day
Low-velocity impact properties and residual compression strength after impact performance are used to evaluate composite materials for many applications. In this research, low-velocity drop-weight impact and compression after impact performance of four continuous fiber reinforcement thermoplastic (CFRTP) composites are investigated. Quasi-isotropic samples of GF/PP, CF-PA12, CF-PA6, GF-PA6 were fabricated and tested according to ASTM standards. Three energy levels of 10, 15, and 20 J/mm, were employed in this research. Results indicate that GF/PP exhibits the highest damage resistance and rebound-ability, evidenced by its minimal indentation and damage area, the highest significant damage threshold force, and the highest ratio of impact …

The goal of the Ergo Carbon Workspace is to create a monitor stand that is both lightweight and easily transportable, catering to the needs of modern workspaces. Constructed from carbon fiber, epoxy resin, and a honeycomb core, this design emphasizes portability without sacrificing durability. Incorporating aerospace-grade honeycomb core as well as braided carbon fiber epoxy struts bolsters structural integrity while maintaining a lightweight part. The Ergo Carbon Workspace design facilitates effortless assembly and disassembly, simplifying transportation and packaging. Through the utilization of composite materials, the stand achieves an optimal balance of strength and portability. Ergo Carbon Workspace will also incorporate …

The purpose of this design project is to create a durable lightweight yard game for players of all skill levels. Carbon Cornhole is a composite improvement on the already popular yard game, cornhole, with a new twist. The final product is based on valued feedback from customers. The board is manufactured of carbon fiber/epoxy sandwich panels with a closed cell foam core. The composite design provides a lightweight product. The panels are specifically manufactured to retain their mechanical properties when exposed to outdoor elements such as water and UV radiation. The addition of inlayed LED lights and two new "skill …

3D printed parts offer the ability to generate dimensioned, complex objects with minimal machining touch time and skill, but they are typically very weak and limited in size. Strong and light composite parts require tooling to be created for the fabric to lay on while the resin is curing, but tooling can be quite expensive during the prototyping phase or for low part quantity runs. This study examined the techniques required to weld smaller 3D printed parts together to form large 3D printed tools that could be used as a sacrificial tool for a composite part. In this method, the …
Flexural Creep Comparison To Tts Creep For Pp And Pp-Gf30, Max R. Kauphusman, Regan G. Harvey
Flexural Creep Comparison To Tts Creep For Pp And Pp-Gf30, Max R. Kauphusman, Regan G. Harvey
Research & Creative Achievement Day
Creep testing is one of the most expensive datasets to acquire in both cost ($10k+) and time (2+ months). Dynamic Mechanical Analysis offers a unique opportunity to characterize creep properties of polymers using a technique called Time Temperature Super Positioning (TTSP) in a relatively short period of time. TTSP works by holding either frequency or loading constant at set temperatures for a constant period of time. WLF equations are then used to combine multiple curves from different temperatures into a master curve that can be used to extrapolate out creep performance at designated reference temperatures and save a considerable amount …
