บทคัดย่อ

This work manufactured sandwich composites from glass fiber/poly(vinyl chloride) (GF/PVC) and wood/PVC layers, and their mechanical and morphological properties of the composites in three GF orientation angles were assessed. The effects of K value (or viscosity index) of PVC and Dioctyl phthalate (DOP) loading were of our interests. The GF/PVC was used as core layer whereas wood/ PVC was the cover layers. The experimental results indicated that PVC with low K value was recommended for the GF/ PVC core layer for fabrication of GF/WPVC sandwich composites. The improvement of PVC diffusion at the interface between the GF and the PVC core layer was obtained when using PVC with K value of 58. This was because it could prevent de-lamination between composite layers which would lead to higher mechanical properties of the sandwich composites, except for the tensile modulus. The sandwich composites with 0- GF orientation possessed relatively much higher mechanical properties as compared with those with 45- and 90- GF orientations, especially for the impact strength. Low mechanical properties of the sandwich composites with 45- and 90- GF orientation angles could be overcome by incorporation of DOP plasticizer into the GF/PVC core layer with the recommended DOP loadings of 5-10 parts per hundred by weight of PVC components. ฉ 2010 Wiley Periodicals, Inc.
