Self Healing Mat How Does It Work

1 a bullet hits the polymer gray blue and cuts a hole through it.

Self healing mat how does it work. The mats are made out of a rubber that expands slightly when cut which pushes the two sides of the cut closer together so you still have a mostly smooth surface. 2 some of the bullet s kinetic energy is converted into heat which raises the temperature of the polymer red. Make sure the water is cool. Generally materials will degrade over time due to fatigue environmental conditions or damage incurred during operation.

Whatever type of cutting implement you use on this mat the blade will go between these tiny pieces. How a self healing polymer works simplified. What can we use self healing materials for. They expand because the inside is compressed under pressure and the film surface material is holding them in that way so when they re damaged they get released a tiny bit but are still mostly held in place by the rest of the mat.

3 the hot polymer flows and seals up as the bullet passes through. Better yet if it was really self healing it would re grow the corner itself like a lizard can regrow its tail the actual self healing behaviour is the same as if you were to cut on a thick rubber mat the cut is still there but the material is soft enough that the cut becomes invisible if there s nothing prying it open. You mean to tell me you ve seen self healing polymers on the market. Self healing materials are artificial or synthetically created substances that have the built in ability to automatically repair damages to themselves without any external diagnosis of the problem or human intervention.

100 percent polypropylene mat can be recycled when it is used up after long term intensive use. To soak your mat place it in a bathtub or container that is large enough so your mat can lie flat. Warm or hot water can warp your mat. So i asked him in class.

Easy to read measuring grid on both sides offers double the usage and 30 45 and 60 degree bias lines make creating triangle and star shapes easy. When i was in graduate school i took a seminar class from a chemist whose work in developing self healing polymers was widely admired. He looked at me like i d grown a second head. This separates them rather than cutting into the entire unit of the surface.

Add a solution of cup white vinegar per gallon of cool water and let it soak for 15 to 20 minutes. Self healing cutting mats are made from independent tiny pieces pressed together to create a solid cutting surface. When you cut on the mat using a rotary cutter the blade actually goes between the tiny pieces separating them and not cutting into the surface as a whole unit. Self healing mat provides a cutting surface that lasts longer than others.
