The paper outlines the method and the results of the experimental investigation of interlaminar strength of glass fibre reinforced polyester composites, with the aim of determining the influence that the structure, a reinforcement type and a sort of resin exert upon the interlaminar strength. The tested specimens were fabricated under different formation conditions, namely in eight composition patterns and with three sorts of resin used for polymerization.

Polyester Composites

Glass fibre reinforced polyester composites (GRP) and hybrid nanoclay and glass fibre reinforced polyester nanocomposites (CGRP) are fabricated by vacuum assisted resin infusion technique. The optimum mechanical properties are obtained for CGRP with 3 wt.% nanoclay. Three types of drills (carbide twist drill D 5407060, HSS twist drill BS-328, and HSS end mill (4 flutes “N”-type end mill RH-helical flute)) of 6 mm diameters are used to drill holes on GRP and CGRP. Three different speeds (600, 852, and 1260 rpm) and two different feeds (0.045, 0.1 mm/rev) are selected as process parameters. The effect of process parameter on thrust force and delamination during drilling CGRP is analyzed for optimizing the machining parameters. The delamination factor is low for the optimum process parameter (feed = 0.1 mm/rev and speed 852 rpm). Microstructural analysis confirms that at higher feeds, delamination is low for CGRP drilled with carbide tools. In order to analyze the effect of nanoclay in CGRP on tool wear, 200 holes were drilled on CGRP samples with 3 wt.% nanoclay, and the tool wear is analyzed under optimized parametric condition. Tool wear is high in HSS twist drill compared with carbide drill. The presence of nanoclay also accelerates the tool wear.

The Difference

In this study, the effect of the gel coat composition on tensile strength of glass fibre reinforced polyester (GFRP) composites was evaluated. The experiments were conducted on various gel coat composition and time. Samples were immersed in sea and river water for 6 months to investigate the differences in tensile strength. Optical observation using SEM on the composites surface and comparative analysis in terms of tensile strength were used before and after immersing. As results, the most excellent tensile strength was the gel coat composition consisting of 0.3 kg of reolosil QS-102 with 10 kg of resin SHCP 268BQTN with a value of 51.9 MPa. Tensile strength reduced about 33.4 % compared to other sample where reduced to 46.3401 %. The difference in the composite surface as a result of immersion process on each sample was also discussed in this paper.

The Impact

Varieties in tractable and sway properties of Roselle fiber strengthened polyester composites brought about by the expansion of glass fiber have been investigated. Roselle fiber in mix with glass is magnificent for making economically savvy composite materials. The impact of the plan of glass and Roselle fiber in the readiness of composites have likewise been examined. Direct increment in rigidity is noted because of the expansion of glass. Be that as it may, when lower volume portion of glass is utilized, a cozy blend of Roselle fiber and glass demonstrates the most elevated rigidity. The effect quality demonstrates the most noteworthy worth when a glass volume part of 0.12 is utilized

The Impact

Light curing of fibre composites was studied to explore its usefulness as a cost-effective production technique without unacceptable sacrifices of mechanical properties. Knitted continuous glass fibre reinforced polyester composites were cured by ultraviolet light and vacuum bag resin infusion (VBRI). A maximum thickness of 13 mm could be achieved with this technique. The compressive strength was shown to be independent of laminate thickness; but both the flexural strength and modulus were reduced with increasing thickness of laminate. The impact damage was also studied using drop-weight impact tests. For the same impact energy imposed on the laminates, the delamination areas decreased with laminate thickness.
