Fiber angles

This paper proposes an optimization procedure for maximization of the biaxial buckling load of laminated composite plates using the gradient-based interior-point optimization algorithm. The fiber orientation angle and the thickness of each lamina are considered as continuous design variables of the problem.

In this study, the air-plasma generated by radio-frequency was used to treat bamboo fiber. The treatment parameters were studied to find the suitable condition. The testing on tensile strength, tensile modulus, module Weibull and elongation to break of the fiber, the measurement of contact angles and the SEM analysis showed that at the high frequency of 12 kHz, power 50 W and treatment time of 5 minutes, after air-plasma treatment the tensile strength and tensile modulus of bamboo fiber increased more than double (101.1% and 101.

The chemical modification of bamboo fiber using acetic anhydride has been investigated. Three characterisation technique, namely FTIR, SEM, and contact angle, were used to elucidate the effect of the chemical treatment on the fibers. Modified bamboo fiber has been used as reinforcement for polypropylene (PP) and maleic anhydride grafted polypropylene resins.
