The influence of the temperature on the ultimate tensile strength of the composite materials at constant fiber volume fraction

الملخص EN

The aim of this work is to study the influence of the temperature on the ultimate tensile strength (UTS) of composite material which is manufactured from polyester and E-glass (woven roving, chopped strand mat) as a laminate with a constant fiber volume fraction (VF) of 33%.

The results showed a little effect of temperature on tensile strength in the range of room temperature (RT) to 50 o C for laminates reinforced with E-glass (woven roving) [0/90, ±45,0/90], [0/90] 3, and [0/90, CSM, 0/90], but for laminates reinforced with E-glass chopped strand mat (CSM), as [CSM] 3 and [CSM, 0/90, CSM], a continuous reduction in strength was observed with increasing temperature from (RT) to 60 o C.

The highest percentage reduction in strength was 23% at 60 o Cas compared with (RT) for [CSM]3 laminate.
