The concept of “high-content-adhesive surface treatment” was raised to improve boards’ performance, rather than increasing adhesive absorption of every layer’s porous unit. That is, some BBVs experienced an extra “dipping & drying” to absorb more resin (named “HBBV”). The effect of the amount of knitting threads was also discussed for influencing BBV’s quality. Results indicated that light transmittance of BBVs decreased as the amount of threads added from 3 to 8, while mechanical stiffness increased. Adding two skin layers of HBBVs symmetrically was helpful to enhance 24-hour underwater and 28-hour “boil-dry-boil” dimensional stability for boards with BSVs as core, while more than two pairs of HBBVs were needed to improve 28-hour “boil-dry-boil” dimensional stability of boards with BBVs as core. Two symmetrical surface layers of BBVs/HBBVs provided BSV-boards/BBV-boards with greater bending resistance, while such “surface treatment” would not raise shearing strength of BSV-boards upon 28-hour “boil-dry-boil” treatment. Besides, the data obtained from drop-hammer impact test indicated that more than two pair of surface BBVs or HBBVs were required for significant improvement in anti-impact property.}, DOI = {10.32604/jrm.2021.015461} }
