A stochastic morphological modelling framework has been established to predict the tensile behaviour of Randomly Oriented Strands made ultra-thin Carbon Fibre Reinforced Thermoplastic prepreg tapes. The tape properties from their distributions are generated in a Monte Carlo simulation. Young’s modulus laminate is accurately predicted using classical theory. Fibre-dominant failure also Thermopla...

the idea of combining low weight and good mechanical properties has led to efforts to develop a new light fiber/metal laminate (fml) in the last decade. fmls are hybrid composites consisting of alternating thin layers of metal sheets and fiber-reinforced epoxy prepregs. in this study, the effect of fiber orientation on tensile properties of this material is investigated both analytically and ex...

This study aims to examine the phenomena that occur due projectile penetration on fiber metal laminate. Ballistic testing was carried out experimentally according National Institute of Justice standards (NIJ Standard 0101.06 level III-A) using a 9 mm full-metal jacket with normal angle attack (90° target). The results showed laminate could withstand rate by penetrating first layer (aluminum pla...

background: this in vitro study investigated the marginal fit of two porcelain laminate veneers to help the selection of more accurate veneers in discolored teeth. materials and methods: thirty impressions of metal master die created from the prepared labial surface of an acrylic maxillary central incisor were made and poured with type iv stone. the dies were distributed into test groups (n = 1...

In the realm of aerospace design and performance, there are few boundaries in the never-ending drive for increased performance. This thirst for ever-increased performance of aerospace equipment has driven the aerospace and defense industries into developing exotic, extremely highperformance composites that are pushing the envelope in terms of strength-to-weight ratios, durability, and several o...

GLARE (GLAss REinforced) belongs to a family of fibre-metal laminates currently being used as a skin material for the upper and side shells in the forward and rear fuselage body of A380. This composite material consists of thin layers of aluminium sheets and unidirectional prepreg layers of glass fibres embedded into an epoxy based matrix. GLARE demonstrates excellent resistance to fatigue crac...

Abstract Polystyrene nanofibres reinforced with cellulose nanocrystals have been produced by electrospinning. Two different orientations of the were produced, namely aligned and random, these nanofibrous interleaves investigated both as-spun after thermal treatment. Aligned exhibited a 2500% increase in their Young’s modulus compared to randomly orientated materials, while ultimate tensile stre...

The behaviour of fibre-reinforced composites greatly depends on their layup structures. Through a full-field optimization study based multiple parameters, this paper investigates how different properties change with the layup. aim was to maximize extension-twist coupling performance while ensuring adequate bending stiffness and low thermal warpage make laminate suitable for shape-adaptive helic...
