To simulate the effect of different tensions of fiber on the final products, such as glass epoxy pipes, using CAE ABAQUS, you can consider the following steps:

1. Define Material Properties: Start by defining the material properties of the glass epoxy composite in ABAQUS. This includes specifying the mechanical properties of the fibers (e.g., modulus, strength) and the epoxy matrix.

1. Create a Finite Element Model: Build a finite element model of the filament winding process and the resulting composite pipe in ABAQUS. This involves creating the geometry, meshing the model, and defining the boundary conditions.

1. Apply Fiber Tensions: Define the different tensions of the fibers during the filament winding process. This can be achieved by applying appropriate loads or constraints to the model. You can specify different tension values for different regions or layers of the filament winding.

1. Material Orientation: Consider the orientation of the fibers in the composite pipe. Filament winding typically involves fibers wrapped at different angles and orientations. Ensure that the model reflects the correct fiber orientations to capture their effect on the final product.

1. Simulate Filament Winding Process: Run the simulation in ABAQUS to simulate the filament winding process. This will allow you to observe the behavior of the composite pipe and its response to the applied fiber tensions. You can analyze various mechanical properties, such as stresses, strains, and deformations.

1. Evaluate Results: After the simulation, analyze the results to understand the effect of different fiber tensions on the final product. You can assess the structural integrity, strength, and other performance criteria of the glass epoxy pipe under different tension conditions.

It is important to note that simulating filament winding processes and the behavior of composite materials can be complex. It may require expertise in finite element analysis (FEA) and a good understanding of material behavior. Additionally, it is recommended to validate the simulation results with experimental data to ensure accuracy.

If you encounter specific difficulties or have more detailed questions about using ABAQUS for simulating the filament winding process, it would be beneficial to consult with experts in the field of composite materials and numerical simulations, or to refer to the ABAQUS documentation and user forums for specific guidance.
