Due to the low density, natural fiber such as kenaf fiber provides comparatively good mechanical properties.
Due to their low density and their cellular structure, natural fibre posses very good acoustic and thermal insulation properties and demonstrate many advantageous properties over glass or rockwool fibre example handling and disposal [2].
In summary, a comparative study of mechanical properties of kenaf fibre reinforced composites and other natural fibre are collected together.
Most of them are based study on the mechanical properties of composites reinforced with short and non-woven fibres [12, 13].

An SII TG/DTA6300 differential thermal analyzer was used to determine the heat storage properties of these alloys.
After integrating a series of factors, Al-12Si-2Mg-15Cu alloy was selected as the heat storage alloy.
An obvious feature of solar radiation is that it is affected by weather factors such as the circadian variation, cloud and rain, etc.
According to these results, Al-12Si-2Mg-15Cu alloy and Al-12Si-5Mg-5Cu alloy had better thermal physical properties.

The effects of the AlN content on microstructure, thermal conductivity and thermal expansion properties of composites were investigated.
When ceramic particles are added into a polymer matrix to form a composite, they play an important role in improving mechanical, dielectric insulation and thermal properties of the composites.[6] AlN is a kind of perfect insulation ceramic with high thermal conductivity (320 W/m·K) and low CTE (4.5ppm/°C).[7] In this context, we chose AlN as the filler to improve the thermal conductivity and thermal expansion properties.
We investigated the effect of particle content on themal conductivity and thermal expansion properties.
We could not use higher amounts of AlN than 25% volume fraction due to very low tack and peel properties.
