The use of a tough thermoset polydicyclopentadiene (PDCPD) as a matrix material for composites was explored. A PDCPD-glass fibre composite and an equivalent epoxy composite were compared.Fibre-matrix adhesion quality was assessed by transverse bending tests. The materials were subjected to compression tests, impact tests, static tensile tests and tensile fatigue tests. The results indicate that the tough behaviour of the PDCPD matrix markedly influences the composite damage resistance. The size of the impact damage in the PDCPD composite was half of that in the epoxy composite. The tensile tests indicated no significant difference in tensile strength, but the damage before failure was found to be much more severe in the epoxy samples. The fatigue results showed a much lower variation in fatigue life for the PDCPD material than for the epoxy material, as well as clear differences in damage development for the two materials.

“…Most of them report a remarkable improvement of the fatigue behaviour of CNT and silica modified carbon and glass fibre reinforced polymers (GFRP) [17][18][19][20]. Also for graphene-modified CFRP, there are first results showing a significant enhancement of mechanical properties and fatigue performance [21][22][23].…”

“…Fatigue life improvements of 150-670% were observed in fully compressive, tensile and tensile-dominated loadings. The addition of silica nanoparticles into an epoxy matrix has been shown to enhance the fatigue properties of GFRP composites [15,22]. Incorporation of nanoclay into an epoxy matrix has also been shown to improve the fatigue behavior of FRP composites [23].…”

Two types of glass fiber reinforced plastic (GFRP) composites were fabricated viz., GFRP with neat epoxy matrix (GFRP-neat) and GFRP with hybrid modified epoxy matrix (GFRP-hybrid) containing 9 wt. % of rubber microparticles and 10 wt. % of silica nanoparticles. Fatigue tests were conducted on both the composites under the WISPERX load sequence. The fatigue life of the GFRP-hybrid composite was about 4-5 times higher than that of the GFRP-neat composite. The underlying mechanisms for improved fatigue performance are discussed. A reasonably good correlation was observed between the experimental fatigue life and the fatigue life predicted under the spectrum loads.Keywords: glass fiber composite, silica nanoparticle, rubber particle, spectrum fatigue. * Corresponding author: Tel. +91-80-2508 6310; Fax: +91-80-2508 6301 E-mail address: manjucm@nal.res.in (CM Manjunatha) 2 INTRODUCTIONDue mainly to their high specific strength and stiffness, continuous fiber reinforced plastic (FRP) composites are widely used in various structural applications such as airframes, wind turbines, ship hulls, etc. Such composite structural components experience variable amplitude or spectrum fatigue loads in service. Hence, the fatiguedurability of the composite materials under spectrum loads is an important requirement in these applications.Engineering polymer matrix composite materials generally consist of continuous glass or carbon fibers embedded in a thermosetting epoxy polymer. The epoxy polymer, being an amorphous and highly cross-linked material, is relatively brittle and exhibits a relatively poor resistance to crack initiation and growth, thus affecting the overall mechanical properties, including the fatigue and fracture behavior of FRP composites.One of the ways to improve the mechanical properties of FRPs is to add a second phase of fillers into the epoxy matrix.Incorporation of various types of micro-and nano-sized spherical, fibrous and layered fillers into the epoxy has been shown to improve the mechanical properties of composites [1][2][3]. Considerable improvements in the strength and stiffness [4], and dramatic improvements in the fracture toughness [3][4][5] EXPERIMENTAL Materials and ProcessingThe materials used and the processing employed to manufacture GFRP composites are briefly explained in this section. However, a detailed description of the materials and processing can be found in [24]. The epoxy resin used was LY556 from Huntsman, which is a diglycidyl ether of bisphenol A (DGEBA) resin. The silica (SiO 2 )nanoparticles were obtained as a colloidal silica sol with a concentration of 40 wt.% in LY556 from Nanoresins. The reactive liquid rubber was a carboxyl-terminated butadiene-acrylonitrile (CTBN) rubber, obtained from Nanoresins as a 40 wt.% CTBN-LY556 epoxy adduct. The curing agent was an accelerated methylhexahydrophthalic acid anhydride, HE600 from Nanoresins. The E-glass fiber cloth was a non-crimp-fabric (NCF) with an areal weight of 450 g/m 2 .The required quantity of the neat epoxy resin, th...
