Natural fibres are preferred compared to synthetic fibres because of several advantages such as biodegradable, lightweight, low cost and good mechanical properties.
Tensile properties of roselle fibre were performed to study the tensile properties.
Other advantages include low cost, good mechanical properties, abundantly available, material renewability, biodegradability and abrasive in nature for ease of recycling[1]–[3].
Several significant mechanical properties can be obtained from tensile test such as Young’s modulus, tensile stress, maximum elongation, tensile strain and yield stress.
Increased concentration of NaOH solution affects the tensile properties of roselle fibre.

Zhang et.al. [2] investigated the mechanical properties of nuclear pressure vessel steel and its welded joints by using the micro shear test method.
Olcay Ersel Canyurt [6] has developed the GA based Welding Strength Estimation Model (GAWSEM) to estimate the mechanical properties of the welded joint for the brass materials.
The chemical composition (wt %) of base plate and electrode wire, 3.15 mm diameter (AWS A/S 5.17: EH 14) is shown in table (1) and the mechanical properties of the test plates are given in table 2.
Based on the pilot study results, current, traverse speed and stickout are identified as the control factors and the levels of the factors are decided.

The voids due to the effect of conversion do affect the mechanical properties of concrete.
The factors affect the bond between the deformed bar and concrete are chemical adhesion, friction forces and mechanical anchorage of the ribs against the concrete surface.
These factors may be implicated in three major subject headings: structural characteristics, bar properties, and concrete properties.
In addition, the concrete cylinders were cast for each batch of concrete to determine the fundamental mechanical properties.
The fundamental mechanical properties of concrete are showed in Table 2.

Adding crumb rubber increases crack and frost resistance, but it may decrease the mechanical properties of concrete [8].
Chemical and physical properties of cementitious materials.
To determine the physical and mechanical properties, beam samples of 40×40×160 mm were made.
Thus, 15% of crumb rubber and 10% asbestos-cement powder being added, the optimum mechanical properties of the modified concrete are achieved.
All these factors contribute to the compaction of the matrix structure, the reduction in the number and size of pores.

Gupta's work also highlighted how rheological properties are affected by factors like molecular weight and filler concentration [4].
For an effective binder system, several factors come into play, including favorable flow properties, cost-effectiveness, compatibility with metal powders, efficient debinding, easy disposal, and environmental safety [6].
The different types of polymers and Cu-Polymer compositions can affect the mechanical properties by increasing the weight percent (wt%) polymer, the hardness, compressive strength and density decrease.
The best results were only shown for Cu-PS, which had maximum mechanical properties and low porosity.
Therefore, selecting a polymer with the right chain structure and manipulating factors like processing temperature can help achieve a balance between good flow for molding and desired final properties in the composite.
