Reinforcement of Laminated Veneer Lumber with Ramie Fibre
Abstract
This paper describes a preliminary investigation on the use of ramie fibre/ phenol formaldehyde (PF) composite to reinforce laminated veneer lumber (LVL). This research was conducted in two phases. Phase 1 the ramie fibre was treated with KH-550 silane coupling agent. Phase 2 different numbers of sheets ramie fibre/PF were added in different location of LVL to reinforce. The reinforced LVL was hot pressed at one time. A control group of unreinforced LVL was also manufactured. The results showed that the improvement in level shear properties of reinforced LVL was obvious no matter what loading direction was perpendicular or parallel. The improvement in modulus of elasticity (MOE) and modulus of rupture (MOR) of partial reinforced LVL was obvious too. Preliminary results showed that using ramie fibre composite to reinforce LVL was possible. This research will further broaden the application field of natural fibres, and provide a new improvement way for wood based composite.
