multilayer coating - Opis:
- The article presents the results of impact composite coatings on the thermoplastic matrix with varying amounts of aramid fabrics. To prepare composite coatings applied thermoplastic copolymer of SBS (styrenebutadiene- styrene) with a linear chain, trade name Kraton. To reinforcement selected aramid fabric (Twaron 1210 fiber), a plain weave and a weight of 175 g / m2. As the base polymer coatings used steel sheet with a thickness of 1.0 mm marked with DC01 according to EN 10027-1: 2007. It is a quality steel alloy designed for cold-rolled products. Steel substrate were washed in a solution of water and detergent, and then degreased with acetone. First step was compressed at 180 ° C for 3 minutes without load, and then three minutes with a load of 2 MPa. SBS copolymer film having a thickness of 800 μm. The films again were compressed with fabrics on steel substrate, using the same compression parameters as in the case of a single film. Obtained four reinforced with fabric layers differing in number of layers of fabric and two SBS copolymer coating with different thickness. Impact resistance test consisted of placing the sample of 100 x 100 mm in the base device, and then leaving from the height of 1 meter, a weight of 2 kg terminated spherical indenter having a diameter of 20 mm. All samples from a single impact energy of 19.62 J were subjected to microscopic analysis. The first step was to determine the number of impact, after which the steel substrate coating has been without a break. Then carried out research on coatings by measuring the amount of impact, which was interrupted after the structure of the coating and the steel substrate. As a result of the study, there was no linear relationship between the thickness of coatings and their impact resistance. A significant influence on the resulting damage after an impact is the amount of fabric coating.
