Abstract A suspension of carbon nanotubes in natural latex was obtained by liquid mixing and then used to prepare powder rubber composites modified with means spray drying process. The composite powders were round‐like fine, an average diameter less than about 5 μm. dispersion the matrix improved remarkably compared that mechanical method. By vulcanization tests, it found addition vulcanizing agent necessary for containing should be evidently greater prepared mixing, there existed reversions...
Abstract Curing high‐performance carbon fiber reinforced polymer (CFRP) structures with economical and energy‐efficient off‐oven techniques is important for the widespread application of composite. In this work, we reported a magnetic particle‐induced in situ heating method to controllably cure CFRP laminates stacking sequences [0] 8 , [0/90] 4s [0/45/90/−45] 2s . Results showed that all can undergo consistent, layup‐independent two‐staged protocol via regulating field intensity. Under same...
The study of the deformation and damage evolution behaviour surrounding rock under excavation unloading conditions is vital importance for a deep understanding mechanism roadway failure. In this study, testing using partially hollow thick-walled cylinder cement mortar specimen with dimensions 280 mm (height) × 200 (outer diameter) 60 (inner solid height at bottom was performed to investigate response failure characteristics rock. experimental results showed that higher deviatoric stress...
The essence of roadway excavation is a process unloading at the periphery, and influence paths on surrounding rock damage directly related to selection support design construction technology. real stress state often affected by different conditions in actual process. Therefore, testing system model was developed simulate arch under conditions. Small hollow cylindrical specimens used this experiment were made cement mortar. load inner cavity removed constant action external pressure axial...
The deformation and failure of the surrounding rock during roadway excavation often determine choice supporting methods. To study behavior modes after under unloading stress, structural model tests were carried out with a novel experimental device. present test using partial hollow thick-walled cylinder cement mortar specimen φ200 mm × 280 horizontal central circular hole 60 diameter height 160 was conducted to investigate deformation, characteristics, AE response whole testing process from...
The safety monitoring of coal roadways roof is the key to prevent accidents and ensure mines safety. However, blind zones caused by traditional methods one main reasons frequent accidents. To production, a novel method proposed in this paper, which based on distributed optical fiber sensing (DOFS) pre-stretched layout at fixed points (POFLF). research approach has been carried out through analysis DOFS strain POFLF theory, with help indoor experiment. Finally was applied field roadway roof....
Abstract Lithology and architecture of alluvial fans can become too complicated, influenced by rapid deposition sediments near the provenance. The paleo-environment oil sand be often better observed through drilling cores well loggings, rather than outcrops seismic attributes, for are usually covered modern not allowed to exploited while waves cannot detect layers shallow above 200m. Reservoirs mostly buried at extremely depths from 0 500m. Oil is found within a mixture carbonates....
