Abstract

Fibre-reinforced composite (FRP) rna;teriaJ are found widely used nowadays in various industries such as offshore, aerospace, medical science and also in construction industries. The application of fibre-reintorced composite material have overcome the use of conventional materials such as steel, timber and concrete due to the composite material characteristics which are high in stiffuess, toughness. strength with low density that could contribute in reducing manufacturing and transportation cost. However, the environmental effect on the FRP followed by several failure of FRP when overload stress provides interests to study different performance of fracture surface of FRP as fracture mode of FRP could be only one mode or even more than one mode depends on the force act on it and also surrounding that may change the mechanical properties of the advanced material. This paper is an attempt to study the fracture surface of FRP composite and uncover the failure mechanism that may occur in the composite due to high load applied on it by visual and microscopic technique. The cause of the failure, the performance and propagation of the surface fracture may be determined by careful and thorough observation. Visual inspection of the fractured surface of FRP composite is to determine the most critical fracture part that can be seen with our naked eyes as before using any other microscopic instrument, the first step in fracture inspection is visually observe any fracture that can be seen visually. Digital Microscopic image analyser is used to observe the fractured surfaces of glass and epoxy composite in further detail to reveal the failure modes of the FRP such as delamination, fibre breakage. de-bonding between fibre and matrix and fibre pullout region that may weaken the performance of the composite. The tensile test results shows the predictable pattern of brittle FR P pipe material resulting the objectives of this project have been achieved as several mode of failure on the surface of FRP pipe composite were revealed due to tensile load act on it.
