Abstract: Abstract The adverse effect of knit‐line formation on the mechanical properties of thermoplastics has been well documented for unfilled materials. A majority of these investigations concern amorphous polymers, whereas a number of engineering polymers are semicrystalline and also contain reinforcing fillers and fibers. The present investigation deals with the effect of knit‐lines on the mechanical behavior of unfilled and glass fiber‐reinforced semicrystalline polymers, such as polypropylene, poly(butylene ter…
