Screw Withdrawal Strength of WPC Reinforced with Woven Fiber Fabric Note: Values in the parentheses are standard deviations According to the multivariate analysis of variance test the effects of fiber type wood flour coupling agent and plastic type which are the main factors on the screw withdrawal strength were statistically significant ... 【Get Price】

the withdrawal strength of screws in the test samples with dimensions of 50 mm × 50 mm × 4 mm. The pilot hole diameter for each screw was 2.7 mm. The screw diameter of 4.2 mm and length of 38 mm was used in this study. The thread pitch of screw was 1.4 mm. The screws were hand-driven 15 ± 0.5 mm into the test samples. Nine samples for each 【Get Price】

Highlights Withdrawal resistance (WR) of screws in the commercial WPC panels was investigated. The effect of pilot hole diameter on WR of screws in WPC panels were investigated. WR of various screws including sheet metal drywall and wood screws were compared. WR of the WPC panels were compared with those of conventional MDF and particleboard. 【Get Price】

The results of withdrawal strengths of fasteners (screws and nails) for WPC samples are shown in Fig. 2a and b. The fastener withdrawal strengths are reduced by increasing MDF dust content as observed for all samples. A similar result was observed for WPCs by Chavooshi and Madhoushi and Madhoushi et al. . The greatest increase in the fastener ... 【Get Price】

Flexural strength screw and nail withdrawal resistance and impact strength of wood plastic composites declined with the increase in fiber content from 60 to 80%. This was attributed to the lack ... 【Get Price】
