Hydrogen bonding between the carboxylic group of PLA and the silica bonded group affected the increment in mechanical properties of composites.
PLA is a biodegradable polyester material with good mechanical and thermal properties.
However, both silica nanoparticles and coconut fibers could be affected in order to increase the mechanical properties of composites [9, 10] by hydrogen bonding between the carboxylic group of PLA and the silica bonded group [11].
Another factor that helped to increase the compressive properties was the ability of attachment with the PLA matrix of silica nanoparticles and coconut fibers.

Introduction The results of coating binder migration in coating layer influence the structure and surface state of coated paper, finally affect the coated paper properties such as printing properties[1-3].
Coated paper printing performance is affected by many factors, such as pigment type and size, binder type and dosage, coating and printing production process and so on, coating binder and its migration is not the only factor influenced the printing properties.
This paper tried to use binder relative concentration in the coating surface and its distribution in z-direction and influence factors to illustrate effects of binder migration on coated paper printing properties.
Some factors such as pigment type, pigment particle size, coating binder types and dosage influence the coating structure, and they all impact the coated paper properties, so binder migration is not a single reflects.
Some factors impact K&N value such as coating surface properties, roughness, smoothness, specific surface area, etc.

Therefore, preheating can influence the properties and fracture behavior of the joint by affecting the IMCs thickness and wetting ability of the aluminum alloy layer on the steel surface.
Meanwhile, the mechanical properties of aluminum alloy 6061 and Mild Steel Q235 were shown in Table 1 and Table 2.
Table 1 Mechanical Properties of Aluminium Alloy 6061.
Because the melting point of aluminum is lower than the filler metals used in this research, during joining of aluminum to mild steel, several factors can affect the porosity formation, such as solubility of the gas in the molten metal, temperature, viscosity of the molten pool and solidification time of the molten pool.
