Kevlar (with a capital K as it is a trade name, the fiber itself is an aramid fiber) has an interesting feature: it is TRES resistant to breakage and Section. Le problème correspondant, is that it is very difficult to cut cleanly with scissors fabric not impregnated. If you try, ça va […]

When using the composite, we are led to evaluate in what sense the forces of extension and compression will be exercised. Indeed, unlike metals, composites have a strength "anisotropic", that is to say, it depends on the direction of fibers embedded in resin. Although qu'isotropes, that is to say equally strong in all directions, les métaux […] A fairly comprehensive document while remaining (almost) easy to read on polymers and composites. It includes explanations on how to place the fibers on different forms. Polymers and composites La pompe à vide est utilisée pour plaquer une paroi souple sur un moule, crushing the layers of a composite plate against a flat surface or complex. It uses suction to flush the fibers of any air bubbles, and the pressure for pressing against each other. On obtient ainsi […] |
