Theoretical Analysis on the Thermal and Electrical Properties of Fiber Reinforced Laminates Modified with CNTs

In the present study, the effect of the multi-walled carbon nanotubes (MWCNTs) fillers weight fraction on the mechanical, electrical, and thermal properties of the epoxy was calculated analytically. The results were then compared and it was found out that the MWCNTS has a significant effect on the electrical conductivity of the epoxy. The MWCNT modified epoxy composites were considered as the matrix material to design quasi-isotropic carbon fibre/epoxy composite. The change of the weight fraction of the MWCNTs on the mechanical, electrical, and thermal properties of the carbon fibre/epoxy laminates was also calculated. Finally, the hygrothermal load and the bending load response of the laminated composites were researched. MWCNTs fix the mismatch between the hygrothermal properties of the epoxy matrix and the carbon fiber.

Bu çalışmada, çoğul duvarlı karbon nanotüplerin (MWCNT) epoksinin mekanik, elektrik ve ısıl özellikleri üzerindeki etkisi analitik olarak hesaplanmıştır. MWCNT’nin epoksinin elektriksel iletkenliği üzerinde önemli bir etkiye sahip olduğu bulunmuştur. MWCNT modifiyeli epoksi malzeme ile karbon fiber/epoksi tabakalı kompozit malzemeler tasarlanmıştır. MWCNT’lerin ağırlıkça katkısının karbon fiber/epoksi kompozitlerin mekanik, elektriksel ve termal özellikleri üzerindeki etkisi de hesaplanmıştır. Son olarak, MWCNT takviyeli tabakalı kompozitlerin higrotermal yük ve eğilme yükü altındaki tepkileri araştırılmıştır. MWCNT’lerin, epoksi matris ve karbon fiberin ısı ve neme bağlı özellikleri arasındaki uyumsuzluğu azalttığı sonucuna varılmıştır.
