“…6 The influence of functionalized MWCNTs into grafted Glass fibre fabric epoxy composites improve the interlaminar shear, tensile and bending strengths and interfacial adhesion was enhanced because of restriction of the mobility of epoxy molecules around the fibres and repair of interface defects and by opposing the interface debonding. 7 When MWCNTs were chemically grafted onto surfaces of the amino silane treated Glass fabric/epoxy composites, it resulted in a decrease (11%) in ultimate tensile strength while toughness of the multi-scale composite laminates was increased up to 57%. Bending test shows that Grafted MWCNT into Glass fabrics provides better recovery after initial fall of load.…”

In this present study, the mechanical properties of Glass/Carbon hybrid composite reinforced with epoxy resin with and without multi-walled carbon nanotubes (MWCNT) were investigated. The composite under Experimental analysis were fabricated by using both Hand layup and Vacuum bag moulding processes. The main purpose of including MWCNT as a reinforcement material with epoxy is to reduce the existence of voids or cavities and to enhance the mechanical properties of Glass/Carbon hybrid composites. Because of their extraordinary mechanical properties and high aspect ratio, MWCNTs are considered to be ideal candidates for polymer reinforcement. The percentages of MWCNT selected for the study are 2%, 3% and 4% with the hybrid composites. The effect of MWCNT on mechanical properties such as tensile strength, compressive strength, flexural strength, impact strength, hardness and percentage of water absorption of the hybrid composites were determined as per American Society for Testing and Materials (ASTM) standards. The result from the study shows that the mechanical properties of hybrid composites were improved with the addition of small amount of MWCNT than without MWCNT. The fractured specimen from Tensile test is examined by using Energy Dispersive X-Ray Analysis (EDX)to study the alignment of the fibres, fibre-matrix adhesion, voids and filler agglomeration. This investigation provides proper guidelines to designers on enhancing mechanical properties of Glass/Carbon composite structures through MWCNT reinforcement for Aircraft structural components.

“…For the epoxyamine curing system, the surface of CNTs with amino, hydroxyl, or epoxy groups is more conducive to improving the fiber/matrix interfacial interaction. 20 Zeng et al 21 modified GF fabrics by using three types of functionalized multi-walled carbon nanotubes (MWCNTs) (with carboxyl, hydroxyl, and amino groups) and found that the hydroxyl-functionalized CNTs could effectively promote the interfacial properties of resultant composites. Li et al 22 reported that amine-functionalized CNTs were more effective in enhancing fiber/matrix interfacial adhesion, resulting in a 23.6% increase in ILSS of the composite.…”

To improve the interfacial adhesion of glass fiber (GF)/epoxy composites, the GF surface was treated by dispersing aliphatic diamine-functionalized multi-walled carbon nanotubes (MWCNTs). Carboxyl MWCNTs were first modified by aliphatic diamine with different alkyl chain lengths and then deposited on the surface of GF. The effect of aliphatic diamine chain lengths on the MWCNTs’ dispersion and interfacial properties of resultant composites was investigated in detail. The results showed that uniform dispersion of MWCNTs and strong fiber/matrix interfacial adhesion could be achieved, based on the grafting of 1,8-octanediamine onto MWCNTs. Compared with the control sample, the interlaminar shear, flexural, and tensile strengths of the treated composites increased by 41%, 29%, and 30%, respectively; the interlaminar fracture toughness and storage modulus in the glass region were significantly enhanced; and the glass transition temperature increased by more than 8°C. This work demonstrates that the carbon nanotubes functionalized by appropriate chain lengths of amine modifier can improve the fiber/matrix interfacial interactions and thus enhance the strength, toughness, and stiffness of fiber-reinforced composites.
