Effects of simple abrasive combing and pretreatments on properties of pineapple leaf fibers (PALF) and PALF-Vinyl ester composite adhesion

Despite being mechanically and environmentally sound, pineapple leaf fibers (PALF) are of little use in Malaysia and the least studied for composite applications. In this study effects of abrasive combing and simple pretreatments on PALF and their adhesion to vinyl ester were investigated. In pineap...
