Název v původním jazyce

An evaluation of mechanical properties and failure modes of multi-layer glass reinforced polypropylene thermoformed composite material to be used in automotive industry

Popis výsledku v původním jazyce

A comprehensive experimental programme was performed with the aim to evaluate strength and E-modulus of the material under different types of loading, static tension, compression and flexure. Tests were performed in three most important directions, warp, weft and +-45 deg. In addition, effects of modified test conditions, like gauge length during compression tests, on final mechanical properties and failure modes were investigated. The experimental programme was completed by evaluation of failure modes at different loading including microscopic and microstructure scale. The most important results are as follows: (i) Flexural strength in both warp and weft directions was similar, the strength in weft direction is slightly higher. (ii) In warp and weft directions, flexural strength was almost comparable with tensile strength, being mostly between 200 and 300 MPa. On the contrary, in 45 deg direction, flexural strength was quite comparable with flexural strength in warp and weft directions unlike tensile tests, where strength in 45 deg direction was considerably lower in comparison with warp and weft directions, more than twice. Further details of the experimental programme and results are discussed in the contribution.
