| 摘要 |
he invention relates to a combination of two different materials, more precisely of polymer materials used in the rotational casting method, with metal nettings, or perforated plates, or other metal elements for the manufacture of products of enhanced resistance. The advantages of the composite materials and the application of the rotational casting method permit the placement of a continuous metal framework into polymer thermoplastic polyethylene or polypropylene materials; the metal framework is made of lamellae, or a metal netting, or a metal frame being of any form and made of a perforated plates. |
