“…Because adhesive wear caused by relative motion, direct contact, and plastic deformation creates wear debris and material transfer from one surface to another, the sliding of the steel ball on the PU surface under a high normal load results in the adhesive wear of the PU by promoting material transfer (Eiss and McCann (29)). In addition, the cyclic loading of the steel ball on the PU surface under the high normal load may initiate subsurface cracks and allow the subsurface cracks to propagate in parallel to a free surface to a certain extent (Lee,et al (26); Nak-Ho and Suh (30)). When the propagated subsurface cracks reach a critical size, the materials are removed from the regions bounded by the free surface and lateral subsurface cracks as platelets (Khun,et al (31)).…”

Polyurethane (PU) samples were immersed in a 1 M HCl solution for different durations from 0 to 90 days to investigate the influence of immersion time on the tribological performance of the samples. The effects of thermal, mechanical, and surface properties of the PU on its tribological performance were also investigated with respect to immersion time. It was found that the friction coefficient of the PU measured against a steel ball significantly decreased with increased immersion time due to the lubricating and cooling effects of absorbed water in the PU during the immersion. The decreased friction of the PU led to the improved wear resistance of the polymer, though the mechanical strength of the PU was reduced by the prolonged immersion due to the increased plasticization of the polymer. The experimental results clearly indicated that the immersion of the PU in the acidic solution for a certain period significantly influenced the tribological performance of the polymer.

“…Generally speaking, the fibers from the protuberances of the original composite surface can bear load effectively in the wear process. And thus, the fibers supporting and resin rich areas are easy to be worn and the cyclic load induces the debonding between the fibers and the matrix [44] due to the plowing of asperities in the counterbody surface, especially for Composite B (initial weak fiber-matrix bonding). Meanwhile, the counterbody surface is also worn out, as shown in Fig.…”

“…The relative heights for the three positions were similar for 0°< θ < 90°. However, since the frictional coefficient is expected to increase from 0°to 90° [50], a greater frictional heating and a higher temperature should be expected for θ ∼ 90°. This explains the shift of the high temperature region to θ ∼90°in P-III to P-IV for UD CFRP under friction dominated heating.…”

A B S T R A C TThis paper presents a comprehensive study on the complex drill-exit temperature characteristics in the drilling of unidirectional (UD) and multidirectional (MD) CFRPs using a state-of-art microscopy infrared imaging system. For the first time, temperature variation and distribution at drill exit have been revealed in full detail, associated with the CFRP material properties and drilling conditions. Results suggest that the actual drill/CFRP interactions have critical but similar effects on the drill-exit temperatures for UD and MD CFRPs. Specifically, three distinct cutting regions with varying temperature characteristics are evident when the main cutting edge is acting on the drill exit material. In all cases, the temperature distribution features elliptical shape, of which the eccentricity depends on the lay-up sequence and the drilling depth. In addition, the real-time temperature profiles and 2D/3D maximum temperature distribution maps are created with high visualization. With the aid of those findings, the relationships between drilling temperature maxima, their locations and drilling depths have been discovered and temperature effects on drill-exit damages have been elucidated for the first time. MD CFRP is proven more difficult to achieve high drilling qualities at certain fiber cutting angles than UD CFRP due to the associated temperature effects. Such important knowledge enables the identification of the heat affected zones and subsequently informs strategies for reducing the negative temperature effects.
