Tensile and compressive properties of interlayer intralayer hybrid composites were investigated in this paper. The tensile modulus compression are the same under mixed ratio, strength is much superior to strength, while increase along with carbon fiber content, values change slightly. influence stacking structures on strengths opposite ratio T/C (tensile/compression) for composites, glass sandwiching can reach maximum value, minimum. For fiber, or asymmetric structures, at a low value....
Finite element analysis and experimental studies are presented on in-plane tensile compressive properties under quasi-static loading for two types of hybrid composites made by using unidirectional T620S carbon E-glass fabrics in a common matrix, epoxy resin. Results also generated plain carbon/epoxy E-glass/epoxy composite laminates. Quantitative data presented. It is observed that composites, placing glass fiber parts alternately every layer (intralayer configuration) gives higher...
The flexural progressive failure modes of carbon fiber and glass (C/G) interlayer intralayer hybrid composites were investigated in this work. Results showed that the bending for are determined by layup structure. Besides, is characterized compression upper layer, when tends to distribute composite fails early, force a multi-stage slightly fluctuating decline fracture area exhibits diamond shape. While distributes middle or bottom time starts late, process one stage sharp force/stress drop,...
The effects of hybridization on the flexural properties interlayer and intralayer Carbon/Glass (C/G) composites were explored in this work. First, theoretical analysis stress distribution hybrid was discussed. experimental results showed that layer structure is critical factor affecting for composites, mixed ratio has no obvious impact. Since carbon fiber distributed at top or bottom surface, can obtain maximum modulus. Some structures even achieve same modulus as pure an excellent strength...
The compression properties and mechanisms of interlayer intralayer Carbon/Glass (C/G) hybrid composites were investigated in this work. As revealed from the experimental results, modulus increases linearly with increase carbon fiber content, following rule mixtures (ROM). C/G ratio is regarded as decisive factor for composites. positive mixing effect exists on strength composites, whereas values are above theoretical calculation values. compressive taking various structures differs largely...
In this study, investigation has been made on the impact response of twill weave carbon fabric/epoxy foam sandwich composites by subjecting two types stacking sequences a composite structure, SC1 and SC2 to quasi-static indentation low velocity loading. had sequence [0/90, ±45, Core, 0/90, ±45], 0/90], respectively. This work was done use material testing system an instrumented Drop-Weight Machine (CEAST 9350 drop tower). Foam structures are mainly used in making Engine Hood. The analysis...
Composite is prepared by filling acrylonitrile–butadiene–styrene copolymer with stainless steel fiber. Its physical properties and electromagnetic shielding effectiveness are tested. When the mass percent of fiber 15%, composite 21–59 dB in frequency band 15 MHz to 3 GHz cylindrical shell made it. Experiments under radiation X-band high power microwave ultra-wideband pulse conducted anechoic chamber while magnetic fuzes connected electrical fire head placed at center shell. Results show good...
As an important basis for the laser processing industry, essence of irradiation process on metal materials is interaction between and materials, involving multidisciplinary cross-coupling optics, thermals mechanics. Due to great influence thermal effect study modern technology generally believed that energy mainly converted into heat. Based finite element software ANSYS, effects such as temperature field distribution rise under can be numerically simulated. In this paper, target plate taken...
Abstract When using the finite element software ANSYS to numerically simulate thermal effect of laser irradiation, calculation results will show some differences with different ways meshing. The model under meshing modes when loaded in form heat flux is studied, which based on process irradiation metal circular plates. effects size ratio and mesh density simulation result are analysed. By comparing theoretical analytical solutions conditions, overall scheme determined first, then influence...
