Whilst the work here focused on self-reinforced PLA/BC in amorphous PLA asapplied to produce self-reinforced UD PLA composites with a higher performance using stereo-complex PLA as the matrix for the fibre/composite reinforcement phase. The melt point of stereo-complex PLA is significantly higher than PLLA or PDLA, depending on composition, at circa 230 C [35], giving a suitable processing window of circa 50 C for the production of self-reinforced PLA composites matrix, this technique could potentially be
