Abstract: |
|||
| A method for manufacturing composite safety helmet includes such steps as making a blanking with needed shape from crude rubber, cutting fabric tape, immersing in a binder, sticking it on the surface of the said blank, positioning on a shaping die, inflating while heating for shaping, hardening and releasing pressure. Its advantages are high productivity and high quality. | |||
