... with considerably improved weather resistance, for example. Weathering Test A weathering method that permits the simulation of natural weathering was used here throughout the entire test cycle. The equipment employed was a Suntest CPS/CPS+ of the Atlas company. The aim of this test is to simulate several years' exposure to light "outdoors" in central Europe. In line with the prevailing conditions in this region, the samples are exposed to wavelengths of some 300 nm and above. The ...

Engineering Plastics. A Clear Thing? Korinna Brammer, Anne Ramlow. UV Protective Coatings. Transparent polymers, such as polycarbonates, must be protected in the open against UV light – for example, by UV protective coatings based on polysiloxanes. Because there are no standardised test procedures, estimating the lifetime of these coatings with the aid of special weathering tests requires a great deal of experience. The development of a new, economical monophase UV protective coating shows th...

It is not for nothing that the new Suntest system XLS+ from Atlas [6] allows the temperature of the flooding water to be regulated between 30 and 50°C. However, there is a requirement to exclude temperatures from 35 to 42°C as at these temperatures bacteria introduced by humans can multiply in t...

A plain weave has the maximum number of crossings and therefore the highest degree of waviness. An atlas fabric only has one crossing per three to four rovings, which reduces the waviness, increases the maximum shear angle and thus the drapability. But regardless of the type of fabric it is a matter of fact that carbon fibers are not plastically d...
