Title: On compression and damage evolution in PTFE and PEEK

Abstract

The well-known Taylor cylinder impact test, that follows the impact of a flat-ended cylindrical rod onto a rigid stationary anvil, is conducted over a range of impact speeds for two polymers, PTFE and PEEK. In previous work experiments and a model were developed to capture the deformation behavior of the rod after impact. A distinctive feature of these works was that a region in which both spatial and temporal variation of both longitudinal and radial deformation showed evidence of changes in phase within the material. This region is X-ray imaged in a range of impacted targets at the I13 Imaging and Coherence beam line at the Diamond synchrotron. Further techniques were fielded to resolve compressed regions within the recovered polymer cylinders that showed a fracture zone in the impact region. In conclusion, this shows the transit of damage from ductile to brittle failure results from previously undetected internal failure.

Shock Compression and Strain Rate Effect in Composites and Polymers

Conference Brown, Eric

Polymers are increasingly being utilized as monolithic materials and composite matrices for structural applications historically reserved for metals. High strain and high strain-rate applications in aerospace, defense, and automotive industries have lead to interest in utilizing the ability of many polymers to withstand extensions to failure of several hundred percent, often without localization or necking and their strong rate dependence. A broad range of characterization techniques will be presented for semi-crystalline polymers and composites including elastic-plastic fracture, split Hopkinson pressure bar (SHPB), plate impact including soft-recovery and lateral gage measurements and Taylor Impact. Gas-launched, plate impact experiments have been performedmore »« less

Equation of State and Damage in Polyethylene

Technical Report Coe, Joshua Damon ; Brown, Eric ; Cady, Carl Mcelhinney ; ...

The dynamic response of polymers differs significantly from those of metals, upon which many of the National Laboratories' deformation, damage, and failure models are based. Their moduli, yield strength, and damage characteristics are highly strain rate-, temperature-, and phase-dependent, requiring models that encompass a wide range of phenomena including some not in equilibrium. Recently, Los Alamos developed the Glassy Amorphous Polymer (GAP)¹ model [1] to address limitations in existing models of polymer deformation. GAP captures both volumetric (equation of state) and deviatoric (shear) response, including a non-equilibrium component to the former (a feature determined to be crucial in capturing themore »« less

Effect of PTFE addition on the transfer film, wear and friction of PEEK-CuO composite

Book Vande Voort, J ; Bahadur, S

This work was done in part as a follow-up of an earlier study which had showed that CuO was effective in reducing the wear of PEEK, but the coefficient of friction of PEEK increased with the addition of CuO. In order to reduce the coefficient of friction, the organic filler PTFE was added to the CUO-PEEK composite so as to increase its appeal for practical applications. Initially, the optimum volume fraction of CuO in PEEK was determined for minimum wear by varying the proportion of the inorganic filler. With this composition as the basis for total filler content, PTFE wasmore »« less
Influence of necking propensity on the dynamic-tensile-extrusion response of fluoropolymers

Conference Brown, Eric N ; Gray Ill, George T ; Trujillo, Carl P

The quasi-static and dynamic responses of two fluoropolymers - polytetrafluoroethylene (PTFE) and polychlorotrifluoroethylene (PCTFE) - have been extensively characterized. Here we investigate the influence of the propensity to neck or not between PCTFE and PTFE on their responses under Dynamic-Tensile-Extrusion (Dyn-TenExt). The Dyn-Ten-Ext technique was originally developed for metals and applied to copper and tantalum spheres by Gray, et al. as a tensile corollary to compressive Taylor Cylinder Impact Testing. Under Taylor Cylinder loading both PTFE and PCTFE exhibit a classic three-diameter ductile deformation pattern. The ductile-to-brittle transition in PTFE occurs at 131 m s{sup -1} with a very tightmore »« less
