POLYMER COMPOSITE EXPERIMENT
USED GLUE AND THREAD PUT STRIPS OF GLUE THEN ADDED STRANDS OF THREAD ALLOWED TO DRY DID 3 DIFFERENT STRIPS AND LAYED THREAD PARALLEL AND PERPENDICULAR ON ONE
1. I DON'T KNOW WHY THE STRIS THE LONG WAY SEEM STRONGER OR SHOULD THEY HAVE?
2. WHAT IF I PULLED FROM SHORT SIDES WHAT WOULD HAPPEN? WHY?
3. WHAT IS THE BULK PHASE IN THE COMPOSITE THE THREAD OR GLUE AND WHY?
CAN SOMEONE HELP ME UNDERSTAND THIS??????
1. The strips that are laid the long way might appear stronger because the strands of thread are aligned in the same direction as the applied force. When a force is applied parallel to the long way of the strips, it has a better chance of transferring the load directly along the length of the strands, which can enhance their overall strength.
2. If you were to pull from the short sides of the strips, it is possible that the strips may not be as strong because the force would be applied in a direction perpendicular to the aligned threads. This could potentially cause the threads to separate or slip past each other, leading to a weaker overall structure.
3. In a composite material, such as the one you created with glue and thread, the bulk phase refers to the component that makes up the majority of the material. In this case, the bulk phase would be the glue, as it holds the threads together and provides the overall structure and stability to the composite. The threads, on the other hand, act as reinforcement within the composite, adding strength and resilience to the glue matrix.
Remember, these explanations are based on typical behavior and assumptions regarding the materials used. It's always a good idea to conduct experiments and testing to verify and understand the specific properties of the materials and composites you are working with.
Sure, I'd be happy to help you understand your polymer composite experiment! Let's go through each of your questions one by one:
1. You mentioned that the strips with thread laid parallel to them seemed stronger. The strength of a composite material depends on various factors such as the properties of the constituents (glue and thread in this case), their alignment, and the bonding between them. In your experiment, laying the thread parallel to the strips of glue creates a stronger bond between the thread and the glue. This increased bonding between the glue and thread can enhance the overall strength of the composite strip compared to the strip where the thread is perpendicular to the strips of glue.
2. If you were to pull from the short sides of the composite strip, the behavior could depend on the orientation of the threads and the strength of the adhesive bond between the thread and the glue. If the adhesive bond is weak, pulling from the short sides might cause the thread to slide or detach from the glue, reducing the overall strength of the composite. On the other hand, if the adhesive bond is strong and the thread orientation is parallel to the pulling direction, the composite strip might be able to withstand a greater force before breaking. To understand what would happen in your specific experiment, it would be helpful to try pulling from the short sides and observe the behavior.
3. In a composite material, there are typically two phases: the matrix and the reinforcement. The matrix is the bulk phase that surrounds and holds the reinforcement in place. In your experiment, the glue acts as the matrix, while the thread acts as the reinforcement. The glue binds the strands of thread together and provides structural support to the composite. Therefore, the glue is considered to be the bulk phase in this composite.
I hope this helps you understand your experiment better! If you have any further questions or need more clarification, feel free to ask.
