| Summary: | Wood–plastic composites (WPCs) have been proposed as an alternative to natural
wood due to their physical and mechanical properties. Development of these composites
from natural fibers is receiving widespread attention partly because of growing
environmental awareness. To dispose of produced waste from industry, low-value fiber
resources could be converted into high-value products. This research studies the
combination of polyvinyl chloride (PVC) to rubberwood (RBW) fiber, to palm oil trunk
fiber, and to palm oil shell (POS) fiber. Composite performance optimization, material
option comparison, basic engineering performance improvement, and durability of
WPCs have been investigated. A two-stage process consisting of compounding and
forming to produce WPCs using 40%–60% natural fiber reinforcements was carried out.
Physical and mechanical properties of the WPCs were studied. The results showed that
WPCs consisting of 60% RBW fiber and 40% PVC yielded the highest modulus of
elasticity and modulus of rupture, which are approximately 90,130 MPa and 433 MPa,
respectively. The ultimate compressive strength with a value of approximately 316 MPa
was achieved from 60% POS fiber and 40% PVC. Reinforcing 40% POS fiber in 60% PVC
exhibited the lowest water absorption rate. The overall result indicates an improvement
of engineering performance, making better use of industrial wastes and indirectly assists environmental conservation endeavor along the process. |
