We investigated the properties of composite board formed using base sheets of aluminum foil-laminated and polyethylene (PE)
plastic-laminated liquid packaging paperboard (LP) as an alternative to recycling these items in wastepaper stream. Boards
of different specific gravities ranging from 0.55 to 0.75 were made by pressing shredded LP blended with urea resin having
resin content of 6%–10% at 180°C. Subsequently, we also prepared mixed particleboard [wood (WD) particles and LP mixed], three-layered
particleboard (LP as the middle layer, WD in the upper and lower layers), and wood particleboard all having resin content
of 10% and various specific gravities. Static bending and internal bonding strengths and thickness swelling of the specimens
were determined to examine their properties. At the same specific gravity, the properties of LP particleboards were affected
by their resin content. The modulus of rupture (MOR), modulus of elasticity (MOE), and internal bond strength of the LP particleboards
increased with increasing specific gravity of the boards at the same resin content, but thickness swelling of the LP particleboards
showed the reverse trend. The average MOR of the LP particleboards approximated that of the mixed particleboards and was greater
than those of the three-layered particleboards and wood particleboards. Internal bond strength and thickness swelling of the
LP particleboards were smaller than those of the other particleboards. Based on the above observations, we deemed that LP
can be made into composite boards with adequate properties either alone or mixed with wood particles. 相似文献

There is a growing desire to improve the properties and use of nonwood plant materials as supplements to wood materials for wood cement-bonded boards (WCBs). This study was conducted to determine the comparative properties of WCBs containing various amounts of discontinuous inorganic fiber materials, such as alkali-resistant glass fiber, normal glass fiber, mineral wool, and nonwood plant materials such as retted flax straw and wheat straw particles. Tested cement-bonded boards were made at wood/additive compositions of 100/0, 90/10, 80/20, 70/30, 60/40, and 50/50 (weight percentages). Seventy-eight laboratory-scale WCBs were produced. Various board properties, such as the modulus of rupture (MOR), internal bonding strength (IB), water absorption (WA), thickness swelling (TS), and linear expansion (LE), were studied. The test results showed that three types of discontinuous inorganic fiber used as reinforcing materials in composites significantly enhanced and modified the performance of WCBs. The mechanical properties and dimensional stability of cement-bonded board were significantly improved with increasing amounts of the additives. MOR and IB were increased; and WA, TS, and LE of boards were reduced by combination with the inorganic fiber materials. The results also indicated that combination with retted flax straw particles only slightly increased the MOR of boards, and wheat straw particles led to marked decreases in all the mechanical properties and the dimensional stability of WCBs.Part of this report was presented at the 50th Annual Meeting of the Japan Wood Research Society, Kyoto, April 2000 相似文献

Light-weight composite panels were manufactured using kenaf core particles as core material and kenaf bast fiber-woven sheets as top and bottom surfaces. Methylene diphenyldiisocyanate (MDI) resin was used as the adhesive with the resin content of 4% for core particles and 50 g/m^2 for bast fiberwoven sheets. The target board densities were set at 0.35.0.45 and 0.55 g/cm^3. The composite panels were evaluated With Japanese Industrial Standard for Particleboards (JIS A 5908- 2003).The results show that the composite panel has high modulus of rupture and internal bonding strength. The properties of 0.45 g/cm^3 density composite panel are: MOR 20.4 MPa. MOE 1.94 MPa, IB 0.36 MPa, WA142%, TS 21%. Kenaf is a good raw material for making light-weight composite panels. 相似文献
