“…The effect of catalyst concentration upon solid content, gel time and adhesive strength is given in Table II. From this table, it can be regarded that: solid content and adhesive strength increased with increasing catalyst concentration and reached their maximum values at 10 per cent, after this concentration, solid content decreased sharply and this can be attributed to the following: when the concentration of catalyst (sodium hydroxide) increased up to 10 per cent, the catalyst accelerates the reaction involving dimethylene ether bridges or hydroxyl methyl groups due to the increase in the pH of the basic medium (Usmani and Salyer, 1981) resulting in increase in the water content and this leads to large drop in solid content value. Adhesive strength also decreased after 10 per cent of catalyst concentration and this can be due to reduction in the number of hydroxyl groups in the resin.…”

PurposeThe purpose of this paper is to examine the preparation of adhesive by incorporation of kraft lignin as an agricultural waste into phenol formaldehyde (PF) resin structure and to evaluate the mechanical properties of lignin phenol formaldehyde (LPF) as wood adhesive.Design/methodology/approachPF resin (resole) was prepared using sodium hydroxide as a catalyst. Different concentrations of lignin were incorporated into PF resin structure. The effect of lignin concentration, formaldehyde to phenol molar ratio, catalyst concentration, temperature and time upon solid content, adhesive strength and gel time was studied. The kraft lignin, PF and LPF resins were characterised using FT‐IR and thermal analysis.FindingsThe incorporation of lignin into PF resin (resole) increases adhesive strength and decreases gel time. The highest adhesive strength and the lowest gel time were achieved at 90 per cent of kraft lignin, formaldehyde to phenol molar ratio, 7.2 and 10 per cent of catalyst, after 4 h and at 80°C.Research limitations/implicationsThe effect of different concentrations of kraft lignin, formaldehyde/phenol molar ratio, catalyst concentration, temperatures and time upon solid content, gel time and adhesive strength was studied.Practical implicationsIncorporation of kraft lignin into resole leads to adhesive with improved mechanical properties.Originality/valueIt was found that LPF resin is better than PF resin from the economical point of view and has the better mechanical properties.

“…In recent years, greater emphasis has been rendered in the development of fiber‐filled composites based on natural fibers5–12 with a view to replace glass fibers either solely or in part for various applications. The scope for using jute fiber in place of the traditional glass fibers stems from the lower specific gravity and workable specific modulus of the jute fiber (1.45 and 19 GPa, respectively) compared to those of glass (2.56 and 29 GPa, respectively).…”

Cyanoethylation of jute fibers in the form of nonwoven fabric was studied, and these chemically modified fibers were used to make jute-polyester composites. The dynamic mechanical thermal properties of unsaturated polyester resin (cured) and composites of unmodified and chemically modified jute-polyester were studied by using a dynamic mechanical analyzer over a wide temperature range. The data suggest that the storage modulus and thermal transition temperature of the composites increased enormously due to cyanoethylation of fiber. An increase of the storage modulus of composites, prepared from chemically modified fiber, indicates its higher stiffness as compared to a composite prepared from unmodified fiber. It is also observed that incorporation of jute fiber (both unmodified and modified) with the unsaturated resin reduced the tan ␦ peak height remarkably. Composites prepared from cyanoethylated jute show better creep resistance at comparatively lower temperatures. On the contrary, a reversed phenomenon is observed at higher temperatures (120°C and above). Scanning electron micrographs of tensile fracture surfaces of unmodified and modified jute-polyester composites clearly demonstrate better fiber-matrix bonding in the case of the latter.

“…The following conclusions are drawn from the present work.The 4 layered jute glass jute glass specimen is more stiffer than 3 layered jute glass jute specimen because the percentage reduction in deflection is 37.5%, and also it is 3.2% more hard enough than 3 layered one ( Figures 5 and 6) [6][7][8][9][10]. The interlinear shear stresses are 81.23% more in 3 layered one than the 4 layered one.…”

A composite is a heterogeneous material created by the synthetic assembly of two or more components constituting reinforcing matrix and a compatible matrix to obtain specific characteristics and properties. In this project we selected jute fiber, E-Glass and it is embedded in a biopolymer matrix system (epoxy), the task of which is to hold the fibers together, this provides and stabilizes the shape of the composite structure, transmits the shear forces between the mechanically high-quality fibers, and protects them against radiation and other aggressive media and the specimen is prepared. The component is conditioned and prepared for testing and subjected to tensile, compression, hardness and bending test calculating the element results with ansys by using the test results. The main aim of this project is to reduce the impact on the environment, by preparing specimen using recyclable natural fibers.
