Hi,

I found out that Kevlar is a crystalline structured polymer, and this is one of the factors about why its so strong. Could someone explain to me why crystallinity affects strenght?

Thanks.

Crystals have incredible intermolecular strength, the crystal like structure of the polymer would allow high intermolecular forces which can distribute the force of an impact over this network of the polymer and the network of crystalline strand interactions to absorb the energy instead of having it stay in a zone of the material and possibly breaking the polymer bonds and hence the material.
