Due to the high interest in use of glass/epoxy laminates aerospace applications, aviation, and as cryogenic tanks, it is crucial understand behavior composites under challenging environmental conditions. Polymer are exposed low temperatures, including which can lead initiation microdamage. This paper investigates damage initiation/accumulation its influence on properties cross-ply woven glass fiber epoxy at temperatures compared room temperature To evaluate a low-temperature environment...

National Road Safety Program 2013-2020 assumes to reduce fatalities by half and seriously injured 40% from 2010 2020. It means that no more than 2,000 people per year should die on Polish roads 6,900 suffer serious injuries in traffic accidents. The experience of other European Union countries with improving road safety gives hope these goals are still realistic, but there is a need intensify the activities carried out this area. In Poland, institutions taking part process safety: state...
