Carbon‐fiber‐reinforced acrylonitrile–styrene–acrylate composites: Mechanical and rheological properties and electrical resistivity

Abstract

The aim of this study was to improve the mechanical properties of an acrylonitrile-styrene-acrylate copolymer (ASA) with the help of carbon fibers (CFs). Additionally, the effects of the CFs on the morphology, rheological properties, dynamical mechanical properties, electrical resistivity, and heat resistance of the ASA composites were studied with scanning electron microscopy, rotational rheometry, and dynamic thermomechanical analysis (DMA). The mechanical properties of the ASA composites were enhanced largely by the CFs. The maximum tensile strength of the ASA/CF composites reached 107.2 MPa. The flexural strength and flexural modulus also reached 162.7 MPa and 12.4 GPa, respectively. These findings were better than those of neat ASA; this was attributed to the excellent interfacial adhesion between the CFs and ASA resin. Rheological experiments proved that the viscosity and storage modulus (G 0 ) values of the ASA/CF composites did not increase until the CF content reached 20%. The DMA outcomes confirmed that the glass-transition temperature of the ASA composites was elevated from 120.6 to 1258C. Importantly, the G 0 values of the composites with 20 and 30% CFs showed a large increase during heating. In addition, the ASA/CF composites exhibited excellent conductivity and heat resistance.

Basalt Fiber Composites with Reduced Thermal Expansion for Additive Manufacturing

“…The incorporation of fibers restrains the mobility of the polymer chains [ 43 , 54 ], justifying the reduction CTE in the composites. In the XY specimens, the fibers are preferentially oriented along the printed bead [ 7 ], accounting for the greater CTE reduction in this direction than XZ, where fibers contribute to a lesser extent to these mechanisms.…”

“…In the XZ configuration, the BFs are not so interconnected to each other, so they are not able to prevent in the same amount the deformation in this direction than in XY. The incorporation of fibers restrains the mobility of the polymer chains [43,54], justifying the reduction CTE in the composites. In the XY specimens, the fibers are preferentially oriented along the printed bead [7], accounting for the greater CTE reduction in this direction than XZ, where fibers contribute to a lesser extent to these mechanisms.…”

“…The substitution of the butadiene rubber by an acrylate elastomer improves the weathering shown by ABS [21]. The mechanical performance of ASA can be further improved by combining it with other polymers or fibres [22].…”

Thermal aging properties and electric heating behaviors of carbon fiber paper-based electric heating wood floors

“…Endowing wood floors with electric heating functionality raises the value of wood floor products, saves energy, and reduces environmental pollution (Kollmann et al 1967;Armstrong 1978;Lin et al 2005;Song et al 2015a). Another merit of electric heating wood floor is the cost effectiveness due to the reduction of electric energy consumption (Zhang et al 2016). This electric heating technology developed rapidly in China and relevant products have appeared on the market.…”

“…This electric heating technology developed rapidly in China and relevant products have appeared on the market. Recently, carbon fiber paperbased electric heating membrane has been used in electric heating wood floors due to its good thermal stability, low cost, and adjustable electrical conductivity (Shi and Wang 2014;Yuan and Fu 2014;Zhang et al 2016). Furthermore, carbon fiber paper can emit an infrared ray of 8 μm to 15 μm during use that is beneficial to the human body (Yuan and Fu 2014).…”
