This paper investigates the damage behavior of thermoset and thermoplastic fiber-reinforced composites. The specimens were subjected to low-velocity impacts (LVI) to produce barely visible impact damages (BVID). To compare the dependency of the matrix system and the laminate lay-up on the impact damage, four test series were set up. Therefore, lami...

Filament winding is a well-established process for the production of high-end fully wrapped composite circular structures like pressure vessels for gas fuels in automotive and other lightweight applications. Caused by the fact that thermoset matrix systems are easier to process due to their low viscosities compared to thermoplastic matrix systems,...

The effect of process variables such as shear rate and temperature on the viscosity of polypropylene during the processing of thermoplastic based composites was investigated in this study. The melt impregnation is used in the process of continuous glass fibre reinforced thermoplastic composites. To develop a mathematical model for roving impregnati...

The high melt viscosity and a low heat conduction of thermoplastic materials are the technical reasons, why the production of reinforced thermoplastics is so challenging. A solution is the pin assisted melt impregnation, whose constructive elaboration is illustrated in this poster.The main aim is to create a mathematical model, which is able to giv...
