Abstract
The study was reflection of the impact of the widespread use of polymer Novolak composite reinforced Glass fiber and Asbestos fiber once again with weight fraction 60% on the physical properties, which included (Hardness, Compressive deformation, compressive modulus of elasticity, Flexural modulus of elasticity, Resilience modulus, the maximum of Flexural strength, Flexural strain energy and Shear strength inner layers); it is known how much important the media as a source of bacterial contamination, which contributes directly or indirectly in the process of aging of these materials. These Novolak composite reinforced, prepared by weight fraction of (10%) and (14%) of the Hexamethylene-tetraamine (HMTA) hardener material. It showed the results of the comparison, the composite prepared to offer bacterial media, negatively effect on Hardness, Compressive strengths, Flexural strength and Flexural strain stored energy The research also concluded clear results, which is that there is the possibility to delay the aging process of the presence of bacterial circles, using glass fibers in the polymer Novolak composite reinforced, more than it is the use of asbestos fiber. And increase the weight fraction of hardener material to be 14%, coefficient of resilience reversal less than it is in the rest of the models, which leads to raise the value of the work done at the end of proportionality.
