Fiberglass material Properties

11/01/2007 4:43 AM

Im new to working with fiberglass, I have some info on the mechanical properties of 3 materials that go into a fiberglass balsa composite, 2 are structural cloths and one layer is for the surface finish.

I have the followin info about these materials.

youngs modulus.

shear modulus

tensile strength

compressive strength

and shear strength.

Unfortunately i dont have a density or poissons ratio for analysis purposes.

I cannot ask the supplier for these properties but I have names of the materials (im not sure if there is enough info in these names to fully sedcribe them).

1: Plane weave 7500, woven glass (for surface finish)

2 : Rov mat ep778A structural cloth 6 layers

3:: FabMt structural cloth one layer.

Im sure that there are hundreds of different types of Fiberglass cloths/ Fiberglass Mats in use? I just cannot seem to find info online about the whole topic. If anyone has any advice it would be much appreciated

Are the moduli you have for the finished, cured product or for the glass used in the cloth? There shold be information available somewhere relating to the proportion of fibre to matrix you end up with. And of course in orthogonal directions.
