I am modelling a specimen that involves a peelable fiberglass shim using finite element analysis but I cant find the needed values to model it anywhere not even from the company that manufactured it.I have attached a picture of the peelable fiberglass for guidance sake.Thanks y'all.
Dear Cephas Yaw Attahu,
The Young's modulus and poissons' ratio of a composite material can be approximately calculated with reasonable accuracy by the rule of mixtures, it states that the modulus of the Composite material is the Modulus of the constituent materials times their proportion in the composite . More details are available in book on Mechanics of Composites ( R M Jones / A K Kaw / R E Gibson ).
Yc = Vf*Yf + Vm*Ym
Y is youngs modulus
V is volume fraction
c= composite
m=matrix.
Hello Pramod Vadavkar,I know about the equations you had suggested but I dont have the necessary data to help in the calculation.All that I know is that,the material is a peelable fiberglass shim. By way,Thanks.
Dear Cephas,
You can approximate the properties of the constituent materials to any reputed manufacturers data Sheet. Could you specify what the shim is made of, one component is glass fiber the other one is ------------, any third component etc.
Hi Pramod Vadavkar,I really dont know anything else other than what I had given.The manufacturing company that made the product and the entity that gave me the material are all reluctant in sharing any more information. Thats the more reason I attached a picture of the product for clarification and identification purposes.
In such a case i think that the fiber may be E glass or S glass and the matrix may be a elastomer or a thermoplastic. You may have to try different combinations to arrive at the properties which give you exact response of the system to the stimulus (load / heat / etc)
