The purpose of this research is to examine how the size and quantity of water hyacinth (WH) fibers impact their reinforcement of bio-based epoxy resin, with a specific focus on how these factors influence mechanical properties.
However, the main problems of bio-composites are the poor mechanical properties, limited barrier capabilities and thermal stability [8,9]. [8], [9].
In addition to modifying the surface of the fibers, it is essential to consider factors related to particle size.
Photographs of the specimen in each different composition Mechanical properties test.
Overall, it becomes evident that the size of the WH fiber does not affect hardness; conversely, the quantity of WH fiber directly influences the hardness properties. [18] Table 2.

Consideration of Moisture Factor During Material Selection in Plastic Product Design Burak KUKCU1,a,*, Buse DASDEMIR1,b 1Mesan Lock Inc., Silivri, Istanbul, Turkey aburakkukcu@essentra.com, bbusedasdemir@essentra.com Keywords: PA66 GF, Moisture analyze, Product Design, Mechanical properties Abstract.
Humidity is a crucial environmental parameter that can profoundly influence the properties and performance of plastic materials.
For this reason it is important to evaluate the moisture absorption properties of plastic materials.
Its impacts also affect the items' mechanical, thermal, and chemical properties, rather than just their aesthetic or visual elements [5].

It was shown that the rolling of the alloy leads to strong anisotropy in mechanical properties.
The effect of the deformation structure on the mechanical properties and their anisotropy is discussed.
As a result, the work hardened Al-Mg-Sc-Zr alloy may exhibit anisotropy of mechanical properties, which affects the formability of [6].

Strengthening fibers were applied in PC to improve its mechanical properties, and the material obtained is called fiber reinforced polymer concrete (FRPC).
How strengthening fibers affect vibration alleviating properties of FRPC was studies basing on the experiment results. 1.
Relationship among the experimental factors and damping ratio of the specimens were analyzed.
All the factors mentioned above made damping ratio of FRPC decreases as fiber length increases to a certain degree.
Damping ratio testing results show that granite proportion is most important factor affecting damping ratio of the GFRPC specimens.

The pore size, strut thickness, and internal structure of the bone implant are vital factors affecting mechanical strength and Young's modulus.
The deviations can be caused by many factors, such as the inaccurate dimension of the actual printed sample and imperfect pore shape, which affect the mass, volume, and ultimately the actual sample's density.
Such deviations can cause a substantial reduction in the mechanical properties of the actual printed sample and affect the osseointegration of the implant [12].
The directional microstructures may cause anisotropic mechanical properties.
The difference in the pore size and overall size may also affect the actual mechanical properties.
