Purpose Composites 3D printing has the potential to replace conventional manufacturing processes for engineering applications because it allows of complex shapes with possibility reducing cost. This paper aims analyse performance printed fibre reinforced polymer composites investigate energy absorption capabilities and residual properties before after impact. Design/methodology/approach Various...
kevlar is one of the fbers which is used in heavy industrial productions such as, shipping, military and weaving for reinforcement of composites. initial polymer of kevlar or poly(para-phenylene terephthalamide) is an oriented liquid crystal polymer. existence of aromatic group in the main chain leads to formation of rigid-rod molecules in the polymer, high strength and high modulus in it is fb...
