Hole quality plays a crucial role in the production of close-tolerance holes utilized in aircraft assembly. Through drilling experiments of carbon fiber-reinforced plastic composites (CFRP), this study investigates the impact of varying drilling feed and speed conditions on fiber pull-out geometries and resulting hole quality parameters. For this study, hole quality parameters include hole size...

Joint lockup due to dowel misalignment significantly affects joint and concrete pavement performance by causing distresses. The current paper presents an experimental study assess the effectiveness of standard pull-out test in evaluation effect on Jointed Plain Concrete Pavement (JPCP). tests were conducted at two different ages ; 3 28 days. results showed that or individually pulling misaligne...

Abstract The bond between polymer fibers and the surrounding cementitious matrix is essential for development of concrete reinforcement. single fiber pull‐out test (SFPT) standard characterization technique testing strength. However, different phases debonding cannot be distinguished by SFPT. This study investigates from with a modified SFPT proposes methods to change setup generate more valuab...
