Abstract EN
These works study the characterization of thermal and acoustic insulation behavior of Polymer Blend/Recycled Natural Fibers.
Acoustic insulation is an important property in design criterion in buildings and used to avoid the damage caused by the sounds of the explosion of rockets and bombs.
This work is done through reinforcing 80% epoxy resin EP with 20% polycarbonate PC with two different recycled natural fiber RNF (hemp fiber H.F., cornhusk fiber C.H.F) at various weight fractions of (2,4,6) %, the samples, were formed by hand lay-up then the acoustic and thermal insulation tests carried out.
The results show that altering both kinds of RNF can improve acoustic insulation.
Also, it could be noticed that sound insulation efficiency can improve with increasing RNF weight fraction.
Finally, the optimum results got at 6% hemp composite that shows better acoustic insulation than cornhusk composites.
The thermal conductivity improved by increasing the fiber weight fraction.
The maximum value of thermal conductivity for composite samples with (H.F., C.H.F) fibers at (6% wt) equal to (0.71609W/m.
Kº) and (0.73686W/m.
Kº), respectively.
The composite samples with C.H.F.
fibers have slightly higher thermal conductivity value than composite samples with H.F
