Challenges and Prospects of the Use of Horizontal Directional Drilling Techniques for Laying Oil and Gas Pipelines in Nigeria
Abstract: Nigeria pipelines, especially the petroleum and petroleum product pipelines are always vandalized by the sabotage. Huge amount of money is expended to put the damaged pipeline in good shape; and petroleum and petroleum product transfer is sometimes hampered due to leakages and damages caused by the oil thieves. Also huge money is being budgeted yearly to secure the pipelines. To combat this problem, horizontal directional drilling (HDD) is being proposed. …

Experimental Investigation on Hybrid Laminated Composites Reinforced with Basalt-Pineapple-Bamboo Fibers
Abstract: In the majority of technological applications, particularly in automotive and building materials, natural fibre-reinforced composites are now more common. Natural fibre developments have seen a tremendous rise in demand recently. As a filler material, Snail Shell Powder was utilized in the current work to evaluate the mechanical and thermal characteristics of hybrid reinforced composites constructed from natural fibres such as basalt, pineapple, and bamboo. Snail shell powder weighed six grams …

A Study of Nacl Alkali Treated Muntingia calabura fibre Reinforced Composites
Abstract: Natural fibre reinforced composites are more commonly used in various applications due to their biodegradability, low cost, available in nature and less harmful to the environment than synthetic fibres. In the present study, NaCl alkali treated MuntingiaCalaburafibres(MCF) reinforced composites are developed using hand layup technique and evaluated the mechanical properties of the composites. The increase of the NaCl content (up to 20 percent) and the fibre weight is maintained constant …

Effect of machining parameters on the tool wear in drilling of 3D PF C/C composite
Abstract: Carbon–carbon (C/C) composites are broadly used in aerospace, defence, shipbuilding, chemical, and nuclear industries owing to their high strength-to-weight and stiffness-to-weight ratios. However, they are brittle, anisotropic and non-homogeneous in nature, making them difficult to machine. Incorrect machining parameters can cause defects such as burrs, delamination, and fibre bundles pullout. This paper aims to study the hole surface and tool wear during drilling of 3D pierced fabric (PF) carbon-carbon (C/C) …

Effect of Length and Tenor of the Introduction of Sansevieria cylindrica Fibers on the Mechanical Performance of Natural Fiber Composites
Abstract: The substitution of synthetic fillers, such as carbon black, with biobased ones in natural rubber (NR) is a trend of interest in view of increased sustainability and exploitation of agroforest waste in the materials sector. In this work, NR was filled with short fibers extracted from Sansevieria cylindrica (SC) leaves of various length (10, 20, 30, or 40 mm) and in different amounts (3, 6, or 10 g per 100 …
