DYNAMIC STRAIN MONITORING OF COMPOSITE LAMINATES DURING DRILLING USING FIBER BRAGG GRATING AND STRAIN GAUGE SENSORS
Zhu Pingyu (Guangzhou University) Zhichao Yang (Guangzhou University) Yongjing Li (Guangzhou University) Wei Shi (Guangzhou University)
The stress concentrated response zones relative to cutting force on laminated composites are obtained under drilling loads. The location and occurrence of delamination can be identified by strain energy distribution of frequency variations.
ANALYSIS OF FIBER ORIENTATION, MICROSTRUCTURE AND MECHANICAL PROPERTIES OF SPECIMENS MADE FROM FIBER-REINFORCED ABS MANUFACTURED BY FUSED FILAMENT FABRICATION (FFF)
Kay Weidenmann (Karlsruhe Institute of Technology) Sascha Baumann (Fraunhofer ICT) Pascal Pinter (Karlsruhe Institute of Technology) Peter Elsner (Fraunhofer ICT)
This contribution aims on the systematic, quantitative analysis of the fiber orientation using X-ray computed tomography in specimens manufactured from fiber-reinforced ABS by fused filament fabrication and its impact on the mechanical properties.
PROCESS AND MOLD DEVELOPMENT OF DIRECT LONG FIBER REINFORCED FOAM INJECTION MOLDING ON THE EXAMPLE OF POLYCARBONATE AND GLASFIBERS
Christoph Lohr (Karlsruhe Institute of Technology) Andreas Menrath (Fraunhofer ICT) Peter Elsner (Fraunhofer ICT) Kay Weidenmann (Karlsruhe Institute of Technology)
Fiber reinforced polycarbonate (sandwich) blanks were manufactured in a combined foam injection molding and compounding process using a special developed and designed mold. the specimen were investigated on their mechanical properties.
HYBRID RESIN IMPROVES POSITION AND ALIGNMENT OF CONTINUOUSLY REINFORCED PREPREG DURING COMPRESSION COMOLDING WITH SHEET MOLDING COMPOUND
David Bücheler (Fraunhofer ICT) Frank Henning (Karlsruhe Institute of Technology)
Till now, there was no approved procedure for the reliable co-molding of prepreg material with SMC. Introducing a hybrid resin system will enable to manufacture composite parts of complex shape with continuous reinforcements at high quality.
IMPROVEMENT OF COMPOSITE DRAPE FORMING QUALITY BY ENHANCING INTERPLY SLIP
Wei-Ting Wang (University of Bristol) HaNa Yu (University of Bristol) Kevin Potter (University of Bristol) Byung Chul Kim (University of Bristol)
Interply friction is an important factor affecting composite drape forming quality. In this work, the effect of the interleaving materials on the interply friction as well as the interlaminar fracture toughness after curing were investigated.
LASER HOLE CUTTING IN F-12 ARAMID COMPOSITES
Dongbing Geng (Aerospace Research Institute of Materials & Processing Technology) Yi Zhang (Aerospace Research Institute of Materials & Processing Technology) Kai Yi (Aerospace Research Institute of Materials & Processing Technology)
In the present study, laser holes cutting into F-12 laminates with different processing parameters of laser machining and composites properties are carried out by application of the CO2 laser.
MECHANICAL PROPERTIES OF UNIDIRECTIONAL CONTINUOUS CARBON FIBER REINFORCED SHEET MOLDING COMPOUNDS (SMC)
Anna Trauth (Karlsruhe Institute of Technology) David Bücheler (Fraunhofer ICT) Frank Henning (Karlsruhe Institute of Technology) Kay Weidenmann (Karlsruhe Institute of Technology)
Compression molding of unidirectional carbon fiber SMC, based on a hybrid resin system, offers a novel approach to process carbon fiber prepregs with mechanical properties comparable to epoxy based prepreg materials in a more economic way.
