1. Introduction
Carbon fiber reinforced polymer composites have been extensively used in a wide range of applications such as aerospace, automotive, wind energy, marine turbine blades and sports sector because of their superior strength to weight, high thermal stability and excellent corrosion resistance [1,2]. Their low fabrication cost, ease of handling and fatigue damage resistance owe to metal counterpart in various applications [3e5]. In the composites, fiber plays an important role as load bearing component and polymer matrix provides back support to fiber by maintaining its orientation into the composites. The fiber volume content is essentially dominated the mechanical properties of unidirectional carbon fiber polymer matrix composite. In the laminated composites, carbon fiber is mainly responsible for high in-plane mechanical properties, whereas polymer matrix is mainly for out of plane properties. The carbon fiber laminated composites are extremely capable to crack initiation and propagation through various modes of failure [6,7]. The delamination is one of the major crack growth mode, which causes critical depression in in-plane strength and stiffness [8,9]. Another problem is the surface inertness of carbon fiber which exhibits poor interfacial interactions with polymer matrix [10]. All above drawbacks are potentially led to catastrophic failure of the whole composite structure. In this direction several techniques have been introduced to improve mechanical properties (inplane and out of plane) such as Z pinning [11], stitching of fiber [12], designing 3D fabric design [13], fiber surface modification [14e16] and matrix modifications [17e19] etc. These modification methods have been reported with improved inter-laminar mechanical properties at high complexity and cost. Traditionally, matrixmodification is relatively easy and cost effective procedure without compromising other mechanical and structural properties of composite. It is reported that improvement in mechanical properties of composites using matrix modification depends largely on the interface to volume ratio and filler size [20,21]. So in this direction nanofillers are playing important role for the modification in polymer matrix. Some of the work has been already reported on the modifications of composite interface by reinforcing mechanism. The modification combines effect was explained from a variety of interface theories such as chemical bonding [22], wetting, mechanical interlock [23] and local stiffness of polymer matrix [24]. In this area, enhancement in mechanical properties of composites has been reported by incorporating nanoscale fillers such as CNT [25e27], fullerenes [28,29] and nanoclay [30,31]. Ogasawara et al. has reported 60% enhancement in interleminar fracture toughness by incorporating fullerene (0.1e1 wt%) in the matrix resin [28]. On the other hand Vaganov et al. examined the enhancement of 40% in fracture toughness by incorporating 1.0 wt% CNT in epoxy/carbon fiber composites [32]. Also, Xua et al. [31] have reported significant improvement of flexural properties using clay-reinforced epoxy/ carbon fiber composite.
