Preparation and Testing of PAN Carbon/Epoxy Resin Composites

Abstract

Background:Due to light weight, high performance and excellent mechanical properties, carbon fibers are considered a key material in the 21 st century. These are extensively used in many industries for structural usages, such as aerospace, aeronautical, sporting goods applications, and automotive and medical devices, due to their desirable strength to weight properties. Now, these are globally accepted as a high performance and high-strength material. Most of the carbon fibers are derived from polyacrylonitrile fiber precursor. These materials have the potential for fire hazards caused due to heat, smoke, and electric short circuit. Objective:To prepare polyacrylonitrile carbon and epoxy resin laminates in multilayers by hand-lay-up method and testing by ASTM (American Society for Testing and Materials) standards. Method:Polyacrylonitrile carbon fiber/epoxy resin composites are prepared using the hand-lay-up method. For the non-destructive testing, the ultrasonic type is used. For the destructive testing, a universal testing machine is used to test the tensile test, the flexural test and the inter-laminar shear stress test, as per the ASTM standard. Subsequently, the physical properties, such as the density test and the fiber content, the resin content and the void content tests of the laminate are carried out. Results:The experimental results show that the matrix laminates have good mechanical and physical properties. Conclusion:Preparation and testing of polyacrylonitrile carbon/epoxy resin composites are carried out and the prepared laminates exhibit good mechanical and physical properties. Hence, the laminates can be used in many industrial and commercial applications, as a composite material.

The effect of nano-silica on the mechanical properties of composite polyester / carbon fibers

“…A number of samples of tensile tests were prepared from polyester resin reinforced with carbon fiber and nano silica using the sample dimensions of the standard (ASTM D3039) [29] to determine the mechanical properties of the composite materials. The composite materials were prepared from the polyester Siropol-8341, plain weave carbon fiber, and nano silica powder.…”

Recent Development in the Processing, Properties, and Applications of Epoxy-Based Natural Fiber Polymer Biocomposites

“…The processing and fabrication of epoxy-based natural fibers are paramount as the properties of composites are conditioned on the constituent elements of the composites, production technology, and the techniques employed in organizing the fibers [ 4 , 41 , 42 , 43 , 44 ]. In addition to high strength and stiffness at a low density, composite materials exhibit interesting high corrosion and chemical resistance combined with low cost [ 25 ].…”
