“…The immersion time increases from 7 to 14 days, then the load carrying capacity decreases due to the significant moisture absorption, sea water degradation and plasticization of the matrix inter deboning of the fiber matrix interface. Again the load carrying capacity increase, when immersion time from 14 to 21 days is mainly due to the secondary mechanism of sea water provides the foam permeability which increases the 4% of weight gain [18]. There is no much deflects in the line of immersion time; this indicates that the sea water treatment does not the abundant cause of composite material.…”

“…Load carrying capacity decreases with increasing the ratio. This is because of the crack length increases, then the critical stresses are decreased inters reduces the load withstanding capacity [18].

“…And also the load carrying capacity decreases initially and the increases small amount to an increase in immersion time. This is because of the structural degradation occurs within in laminates causes the rapture of blisters, and viscous acid is expelled with immersion [18]. Composite under wet condition showed an initial decrease in the load carrying capacity and again increases due to the plasticization of jute samples caused by moisture absorption.…”

The aim of this work is to evaluate the failure analysis of jute fabric reinforced composite using statistical technique for marine applications. A fracture mechanics approach is proposed to determine the failure load and fracture toughness of the composite. Jute fiber reinforced epoxy composites were fabricated by hand lay-up technique. The polymer composite is intended for marine applications as an alternative material, mainly in high moisture environments. Thus an investigation was conducted to evaluate the fracture mechanic parameter by immersing composite specimens in sea water. The statistical method of Taguchi was used for experimental design. Edge Notched Tension (ENT) and Single Edge Notched Bend (SENB) test were conducted according to the ASTM E1922 and ASTM D5045 respectively. Main effect graphs are obtained to study the effect of a/w (Crack length to width ratio), thickness and immersion time of composite on fracture mechanics parameters. The approach of calculating the percentage of contribution of control factors was established using by analysis of variance (ANOVA). The influence of fracture parameters of control factors can be analysed by using 3-D response surface graph (RSM). The Validation of experimental results for fracture parameters agreed well with the predicted values.

“…Micronisation of the WP to produce microfibres increases the available surface area for cellulosic fibre interaction. It also increases lignin matrix potential for binding on reaction with water [29], thus enhancing the mechanical properties of the composites in addition to the binder and additive activity. The micronisation steps, involving wetting and drying cycle hornify the fibres thus improving dimensional stability and reducing water retention capacity [30,31].…”

In this early study, new cement-bonded bi-composite fibreboard (FB) was made from water hyacinth (WaHy) and waste paper (WP). Ordinary Portland cement (PdCe) used as a binder was mixed with other two additives: gypsum plasters (GyPl) and wood ash (WdAh), in defined proportions to form bonding matrices. The WP and WaHy were pre-treated and a linked process was developed for the mixing and consolidation steps. The FBs produced were based on different proportions of composites, binder, and additives mixed. The FBs produced were made from different proportions of composites, binders, and additives. Improved tensile strength was observed for bi-composite FB from WaHy mixed with WP. In general, FBs having densities in the range of 0.50-0.57 g cm −3 were compared favourably with the ASTM and ANSI standards (95%), thus making the FBs a potential alternative for building and construction purposes. More elaborate research with advanced analytical techniques is hereby suggested.

“…The transition towards sustainable products is in tandem with one of the seventeen United Nation's Sustainable Development Goals that contribute towards a sustainable future. Lignocellulosic fibres possess an advantage over other natural fibres due to its massive annual production which reflected from substantial agriculture activities across the tropical continents especially in China, India and South East Asia [1][2][3]. These materials are favoured for their notable strength-to-density ratio and have been extensively utilised in the production of high-elasticresistance and weight-reduced components for automobiles, aircraft, marines and buildings [4][5][6][7][8][9][10][11].…”

The utilisation of bamboo has the potential of improving the properties of silicone. However, a thorough investigation has yet to be reported on the mechanical properties of bamboo silicone biocomposite. This study was carried out with the aim to quantify the tensile properties and assess the tensile behaviour of bamboo silicone biocomposite using Yeoh hyperelastic constitutive function. The specimens were prepared from the mix of bamboo particulate and pure silicone at various fibre composition ratio (0wt%, 1wt%, 3wt% and 5wt%) cured overnight at room temperature. A uniaxial tensile test was carried out by adopting the ASTM D412 testing standard. The Coefficient of Variation, CV, and the Coefficient of Determination, r 2 , were determined to assess the reliability of the experimental data and fitting model. The results of the determined Yeoh material constants for 5wt% specimen is found to be C 1 = 12.0603×10 -3 MPa, C 2 = 8.7353×10 -5 MPa and C 3 = -11.6165×10 -8 MPa, compared to pure silicone (0wt%) C 1 = 5.6087×10 -3 MPa, C 2 = 8.6639×10 -5 MPa and C 3 = -7.6510×10 -8 MPa. The results indicate that the bamboo fibre improves the stiffness of the silicone rubber by 115 percent. A low variance was exhibited by the experimental data with a CV value of less than 8 percent. The Yeoh Model demonstrated an excellent prediction of the elastic behaviour of bamboo silicone biocomposite with a fitting accuracy of more than 99.93 percent.
